                             Cortelco Systems, Inc.
 
Cortelco designs, develops and markets integrated enterprise communications
systems for routing and controlling the voice, video and data communications of
businesses and other organizations. Our solutions are primarily designed for
enterprises with complex communications needs and small and medium-sized
telephony installations, typically between 25 to 500 communications ports. We
serve a range of vertical markets such as education, retail, government
agencies, emergency-911 services and catalog sales. Some of our customers have
multiple installations networked together and are as large as national retail
chains or multi-location branches of the U.S. government. Our customers include
Circuit City, U-Haul, the Federal Aviation Administration ("FAA"), Bell
Atlantic and Budget Rent-A-Car. Our products are installed in over 7,100
locations worldwide. In addition to selling our products, we also resell
cellular airtime, cellular telephones and third-party voice communications
systems in Puerto Rico. Our products have won numerous awards, including "Best
of Show" awards at CT Expo in 1997 and 1998 and "Product of the Year" awards in
1997 and 1998 from Call Center magazine and in 1999 from Call Center Solutions
magazine.
 
Beginning in the second quarter of fiscal 1998, under the leadership of a new
president, we refocused our overall marketing strategy and began to target
markets for which our systems and product lines are particularly well-suited.
Product development programs have been directed to new software and other
initiatives to strengthen our systems and product lines and generally improve
gross margins. We also increased our sales staff and expanded our dealer and
value added reseller network. As a result of these initiatives, on a pro forma
basis, our revenues increased 36.9% from $17.7 million for the six months ended
January 31, 1998 to $24.2 million for the six months ended January 31, 1999.
 
Our communications systems are based on two platforms, the Millennium and the
DSP Series. Both platforms are based on flexible, modular hardware and software
architectures that are easy to configure. Our platforms support multi-site
networking and other advanced features such as dynamic call routing,
interactive voice response, voicemail and computer telephony integration. The
Millennium is a full-function routing and control system that primarily serves
customers averaging approximately 110 communications ports per installation and
addresses a broad range of voice, video and data communications requirements.
The Millennium also includes automatic call distribution features. The DSP
Series is primarily an advanced automatic call distribution system that also
includes a full-function routing and control system. The DSP Series is
typically used in installations requiring advanced computer telephony
integration applications such as those used in sophisticated call centers. Both
the Millennium and the DSP Series interface with a variety of popular third-
party products through standard protocols.
 
We provide integrated communications systems flexible enough to meet the
immediate needs of enterprises with small to medium-sized installations, yet
scalable enough to accommodate these businesses and organizations as they grow.
Key elements of our strategy include: (1) target enterprises with small to
medium-sized installations at one or more locations; (2) provide customers with
cost-effective, integrated solutions for their voice communications
requirements; (3) expand both our direct sales force and our dealer network to
more aggressively pursue our target markets; and (4) continue to enhance our
core product lines and develop new features and applications that leverage our
existing Millennium and DSP Series platforms. Current development efforts
address emerging market needs, such as unified messaging, voice-over-Internet
Protocol ("IP") and Web-based virtual call center capabilities.
 
In April 1999, Cortelco merged with Cortelco Systems Puerto Rico and acquired
BCS Technologies, Inc. ("BCS"). See "Company Background." We are a Delaware
corporation with executive offices located at 4119 Willow Lake Blvd., Memphis,

                                  Risk Factors
 
This offering involves a high degree of risk. You should carefully consider the
risks and uncertainties described below and the other information in this
prospectus before deciding whether to invest in shares of our common stock.
This prospectus also contains certain forward-looking statements that involve
risks and uncertainties. These statements relate to our future plans,
objectives, expectations and intentions. Our actual results could differ
materially from those discussed in these statements. Factors that could
contribute to these differences include those discussed below and elsewhere in
this prospectus.
 
Our Quarterly Operating Results May Fluctuate
 
Our operating results are likely to fluctuate significantly from quarter to
quarter in the future due to a number of factors, many of which are beyond our
control. As a result, our operating results will likely not meet expectations
in some future quarters, which could have a material adverse effect on the
market price of our common stock. Factors that could affect our quarterly
operating results include the following:
 
    . variations in the mix of products sold
 
    . variations in the timing or size of orders from our customers
 
    . delays or difficulties in introducing new products and/or in
      implementing common applications across both our Millennium and DSP
      Series platforms
 
    . price decreases and other actions by our competitors
 
Quarterly operating results are also likely to fluctuate due to seasonal
factors that affect customers in some of our vertical markets. For example,
U.S. government customers typically make substantial purchases during the
quarter ended October 31, the last quarter of the government's fiscal year, and
these purchases decline significantly in the next quarter. Customers in other
vertical markets such as education and retail have also exhibited seasonal
buying patterns and do not purchase substantial amounts of equipment during the
quarter ended January 31. As a result, revenues in the quarter ended January 31
are often lower than in the previous quarter.
 
The uncertainty of our sales cycle also makes the timing of sales difficult to
predict and may cause fluctuations in our quarterly operating results. The
purchase of our products may involve a significant commitment of our customers'
personnel, financial and other resources to conduct technical evaluations, to
support installation and training and to fund purchases. As a result, our sales
cycles vary from one to six months for Millennium systems, which range in price
from $22,000 to $36,000 depending on the system configuration, and from four to
twelve months for DSP Series systems, which range in price from $75,000 to
$230,000 depending on the system configuration. Additionally, our reliance on
authorized dealers and value added resellers to market our products makes it
even more difficult to predict the timing of sales because we have little
control over their selling efforts to end-user customers.
 
We generally recognize revenues on the date of shipment for Millennium systems,
but upon acceptance for DSP Series systems due to the customized nature of the
installation. Delays in shipment or acceptance due to late deliveries by our
contract manufacturers and other factors beyond our control could adversely
affect revenues in a quarter.
 
Our Recent Results Have Been Affected by One Large Customer
 
Our recent revenues have been significantly influenced by one large customer,
the FAA. In June 1998, we began installing DSP Series systems in approximately
61 FAA sites. The FAA contract accounted for $5.2 million in revenues, or 21.5%
of our pro forma revenues, for the six months ended January 31, 1999. The FAA
contract is expected to be completed in May 1999. We cannot guarantee that we
will be able to obtain sufficient additional customer contracts to avoid a
decline in revenues after the FAA contract is completed.
 
We Have a Limited Combined Operating History
 
We have a limited combined operating history because we only recently acquired
BCS and merged with Cortelco Systems Puerto Rico. Our operating results may be
adversely affected if we are not able to realize anticipated operating
efficiencies through the consolidation of certain administrative and corporate
functions and if we are not able to effectively integrate our corporate
cultures. See "Company Background."
 
                                       4

 
Our Industry Is Highly Competitive with Many Established Competitors
 
The market for our products is highly competitive and subject to rapid
technological change. We expect competition to increase significantly in the
future. Our principal competitors in the voice communications equipment market
include Lucent Technologies, Mitel, NEC, Nortel Networks and Siemens. We also
compete with Aspect Telecommunications and Rockwell Electronic Commerce in the
call center market. As voice and data communications networks converge, data
equipment vendors such as Cisco Systems and 3Com may also compete in our
market. In addition, alliances and mergers between telecommunications and
computer companies may strengthen our competitors' positions or result in new
entrants into our market.
 
Many of our current and potential competitors have significantly greater
financial, technical, marketing, customer services and other resources, greater
name recognition and a larger installed customer base than we do. As a result,
our competitors may be able to respond to new or emerging technologies and
changes faster than we can. They may also be able to devote greater resources
to the development, promotion and sale of their products. Actions by our
competitors could result in price reductions, reduced margins and loss of
market share, any of which would have a material adverse effect on our
financial condition. We cannot assure you that we can compete successfully
against our competitors or that competitive pressures would not have a material
adverse effect on our financial condition and operating results.
 
We Rely on Independent Dealers
 
We have a limited direct sales force and rely on our dealers and value added
resellers to market our products. Authorized dealers and value added resellers
accounted for approximately 30% of our pro forma revenues in fiscal 1998.
Generally, our authorized dealers and value added resellers have no obligation
to sell our products and in many cases also offer our competitors' products.
Our authorized dealers and value added resellers could discontinue selling our
products at any time in favor of our competitors' products or for any other
reason. A reduction or loss of orders from our dealers and value added
resellers could have a material adverse effect on our operating results and
financial condition.
 
We Need to Increase Our Sales Capability
 
In order to increase sales, both domestically and internationally, we will need
to add to our direct sales force, expand existing distribution channels and
establish new distribution channels for our products. A failure to increase
existing or establish new distribution channels or hire personnel necessary to
develop and enhance such distribution channels could have a material adverse
effect on our operating results and financial condition. We have increased our
sales force by approximately 48% since March 31, 1998. We cannot assure you
that new sales personnel, dealers and value added resellers will be effective
at increasing sales or will achieve the same levels of productivity as our
existing sales resources. In addition, as we expand our distribution channels,
our direct sales force, dealers and value added resellers may compete with each
other for the same customers.
 
We Must Keep Pace with Rapid Technological Change to Remain Competitive
 
The markets for our products are characterized by rapid technological change,
evolving industry standards, changes in end-user customer requirements and
frequent new product introductions and enhancements. Our future success will
depend upon our ability to enhance our existing products and to develop and
introduce new products that will achieve market acceptance. A key feature of
our product platforms is their ability to integrate with most standard
protocols and transmission systems, computer telephony integration and
automatic call distribution applications and protocols, operating systems and
databases. In the event that our product platforms cannot be readily integrated
with third-party technology or newly developed technological advances which we
may fail to predict, we could be required to redesign our core product
platforms. In addition, the introduction or market acceptance of products
incorporating superior technologies or the emergence of alternative
technologies and new industry standards could also render our existing
products, as well as products currently under development, obsolete and
unmarketable. Redesigning any of our products may require significant
resources, and any failure to release new products or to enhance or redesign
our existing products in a timely manner could have a material adverse effect
on our operating results and financial condition.
 
We Depend on a Single Source of Supply for Some Components
 
Our products are manufactured using components or subassemblies procured from
third-party suppliers. We receive some electronic components from a single
source. For example, we rely on Siemens to provide the digital signal
processors and associated chip sets for our Millennium and DSP Series products.
We rely on Natural Microsystems to supply the voice processors for our Cortelco
Voice Processing System and on CTP Systems to supply our Orbit Wireless
Communications handsets and base stations. Any interruption in the availability
of components from our key suppliers
 
                                       5

 
could adversely affect our ability to meet our scheduled product deliveries. We
also could experience difficulties in identifying alternative sources or
modifying product designs to use alternative components. Resulting delays or
reductions in product shipments could damage customer relationships and
adversely affect our operating results. Further, a significant increase in the
price of one or more third-party components or subassemblies would have a
material adverse effect on our gross profit and operating results.
 
We Depend on Third-Party Contract Electronic Manufacturers
 
We depend heavily upon the manufacturing capabilities of CMC Industries, Inc.
and Pensar Corporation, our primary contract electronic manufacturers. Our
ability to deliver products on a timely basis could be adversely affected by
any failure of CMC or Pensar to manufacture our products. In addition, we could
have difficulty finding other manufacturers to build our products. Resulting
delays in manufacturing or shipping or an inability to meet customer orders
could adversely affect our customer relationships and our operating results.
 
Our Failure to Manage Growth Could Adversely Affect Us
 
The growth of our business has placed, and may continue to place, a significant
strain on our limited personnel, management and other resources. Our current
management, personnel, systems, procedures and controls may be inadequate to
support our future operations. To manage future growth effectively, we will
need to attract, train, motivate, manage and retain employees successfully, to
integrate new employees into our overall operations and to continue to improve
our operations, financial and management systems. In addition, some of our
customers may require significant support for, and training on, our product
platforms, and we may not have sufficient resources to provide the levels of
service they require. Our failure to provide adequate service could have an
adverse impact on our relationship with our customers and could prevent us from
gaining new customers.
 
We Depend on Key Personnel and Need to Attract Qualified New Employees
 
We are dependent on the principal members of our management team and key
members of our engineering staff. If we lose any of these persons, our
business, financial condition and operating results may be adversely affected.
Due to the specialized nature of our business, we are highly dependent on the
continued service of, and on the ability to attract and retain, qualified
engineering, sales, marketing and senior management personnel. Highly skilled
employees with the education and training that we require, especially qualified
service technicians and employees with significant experience and expertise in
computer telephony integration applications, are in high demand. If we are
unable to hire additional qualified personnel as needed, we may not be able to
grow our business effectively, adequately manage and complete our existing
sales commitments or bid for and execute additional sales opportunities.
Failure to attract and retain the qualified personnel necessary for the
development of our business could have a material adverse effect on our
operating results and financial condition.
 
We Face Many Risks Associated with Expanding Our International Operations
 
Sales outside of the United States and Puerto Rico accounted for approximately
3% of our total pro forma revenues for the six months ended January 31, 1999
and were made primarily through our dealer network. We expect to increase sales
to customers outside of the United States as we establish our distribution
channels in the Caribbean and Latin America. However, foreign markets for our
products may develop more slowly than currently anticipated. We may not be able
to successfully establish international distribution channels, or we may not be
able to hire the additional personnel necessary to support such distribution
channels. In addition, payment cycles with customers located outside the United
States are generally longer than those within the United States.
 
Our Products May Have Undetected Errors Leading to Product Returns or Claims of
Liability
 
Our products, despite testing, may contain undetected errors or failures. The
occurrence of errors could result in product returns and other losses to us or
our customers. This occurrence also could result in the loss of, or delay in,
market acceptance of our products. In addition, any failure by our products to
properly perform could result in claims against us. Our purchase agreements
with our customers typically contain provisions designed to limit our exposure
to potential product liability claims. However, the limitation of liability
provisions contained in our purchase agreements may not be effective as a
result of federal, state or local laws or ordinances or unfavorable judicial
decisions in the United States or other countries. We maintain insurance to
protect against certain claims associated with the use of our products, but our
insurance coverage may not adequately cover all possible claims asserted
against us. In addition, even claims that ultimately are unsuccessful could
result in our expenditure of funds in litigation and management time and
resources.
 
                                       6

 
We May Be Subject to Intellectual Property Litigation
 
As we grow and gain brand recognition, our products are more likely to be
subjected to infringement litigation. Responding to, defending against, or
bringing claims related to our intellectual property rights could result in
substantial costs and diversion of management and technical resources which
could adversely affect our business, operating results and financial condition.
In addition, we rely on a combination of patent, trademark, copyright and trade
secret laws and contractual restrictions to establish and protect our
proprietary rights. These statutory and contractual arrangements may not
provide sufficient protection to prevent misappropriation of our technology or
to deter independent third-party development of similar technologies. Such
litigation could result in our expenditure of funds and management time and
resources.
 
Our Systems May Be Affected by Year 2000 Problems
 
We are heavily dependent upon the ability of our own computer or data-dependent
systems to correctly interpret century data. This includes, but is not limited
to, our systems in information, business, finance, operations and service. Any
failure or malfunctioning on the part of these or other systems could adversely
affect us in ways that are not currently known, discernible, quantifiable or
otherwise anticipated by us. We currently have only limited information on the
Year 2000 compliance of our key suppliers, manufacturers and customers. Our
business and operating results could experience material adverse effects if our
key suppliers or manufacturers were to experience Year 2000 issues that cause
them to delay production or shipment of key components or systems. In addition,
our operating results could experience material adverse effects if any of our
key customers encounter Year 2000 issues that cause them to delay or cancel
substantial purchase orders or delivery of our product. For a discussion of our
Year 2000 plans, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000 Compliance."
 
We Are Controlled by Our Principal Stockholders and Management
 
Upon completion of this offering, our executive officers, directors and
principal stockholders and their affiliates will own approximately     shares,
or   %, of the outstanding shares of common stock, or     shares, or   %, if
the underwriters' over-allotment option is exercised in full. As a result, they
will have the ability to effectively control us and direct our affairs,
including the election of directors and approval of significant corporate
transactions. This concentration of ownership also may have the effect of
delaying, deferring or preventing a change in control of our company and may
make some transactions more difficult or impossible without the support of
these stockholders. The interests of these stockholders may conflict with those
of other stockholders. We also have transactions with businesses in which our
principal stockholders maintain interests, such as CMC. We believe that these
transactions are conducted at an arm's length basis, but we cannot assure you
that these transactions would have the same terms if conducted with an
unrelated third-party.
 
Our Stock Previously Had No Active Public Market and Our Stock Price May Be
Volatile
 
Prior to this offering, there has been no public market for our common stock.
We have applied to list the common stock for trading on the Nasdaq National
Market. The initial public offering price will be determined by negotiations
among the underwriters, us and the selling stockholders and may not be
indicative of the market price for the common stock after this offering. We do
not know the extent to which investor interest will lead to the development of
a public market. Investors may not be able to resell the common stock at or
above the initial public offering price. Many factors could cause the market
price of the common stock after this offering to fluctuate substantially,
including future announcements concerning us or our competitors, variations in
operating results, loss of key customers, changes in pricing policies, or
changes in earnings estimates by analysts. General economic, political and
market conditions may also have a material adverse effect on the price of our
common stock.
 
Some Anti-Takeover Provisions May Affect Our Stock Price
 
The board of directors has the authority to issue up to 10,000,000 shares of
preferred stock and to determine the preferences, rights and privileges of
those shares without any further vote or action by the stockholders. The rights
of the holders of common stock may be adversely affected by the rights of the
holders of any preferred stock that may be issued in the future. Certain
provisions of our certificate of incorporation and bylaws may make it more
difficult for a third-party to acquire control of us without the consent of our
board of directors, even if such changes were favored by a majority of the
stockholders. These include provisions that provide for a staggered board of
directors, prohibit stockholders from taking action by written consent and
restrict the ability of stockholders to call special meetings.
 
                                       7

 
Significant Number of Shares Eligible for Future Sale May Decrease Our Stock
Price
 
Sales of substantial amounts of our common stock in the public market after
this offering, including shares issued upon the exercise of outstanding
options, or the perception that such sales could occur, could adversely affect
the market price of our common stock. These sales also might make it more
difficult for us to raise funds through future offerings of common stock.
 
Upon completion of this offering, we will have outstanding     shares of common
stock. All of the shares sold in this offering will be freely transferable
without restriction or further registration under the Securities Act of 1933,
except for shares purchased by our "affiliates," as defined in Rule 144 under
the Securities Act. The remaining          shares of common stock that will be
outstanding upon completion of this offering are "restricted securities" as
defined in Rule 144. These restricted securities may be sold in the future
without registration under the Securities Act to the extent permitted under
Rule 144, Rule 701, or another exemption under the Securities Act. Cortelco,
our officers, directors and      stockholders will agree not to, without the
prior written consent of J.P. Morgan Securities Inc., directly or indirectly,
sell, offer, contract to sell, transfer the economic risk of ownership in, make
any short sale, pledge or otherwise dispose of any shares of common stock or
any securities convertible into, or exchangeable, or exercisable for, or any
other rights to purchase or acquire shares of common stock owned by them during
the 180-day period commencing on the date of this prospectus.

                           Forward-Looking Statements
 
Statements contained in this prospectus may be forward-looking statements
concerning our operations, economic performance and financial condition.
Forward-looking statements are included, for example, in the discussions about:
the timing and availability of products under development; variations in
operating results; our strategy; Year 2000 issues; and the market for voice
communications equipment. Those forward-looking statements involve risks and
uncertainties and actual results may differ materially from those expressed or
implied in those statements. Factors that could cause differences include, but
are not limited to, those discussed under "Risk Factors" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
                               Company Background
 
We were incorporated on July 23, 1991 as one of several corporations related
through common ownership that were formed to hold various telecommunications
equipment and other businesses that had been acquired primarily from Alcatel,
N.V. in 1990. In August 1993, we became a subsidiary of Cortelco Systems
Holding Corporation, a corporation formed to act as the holding company for the
telecommunications equipment businesses, while CMC Industries, Inc., a contract
electronic manufacturer, became a separate company. See "Business--
Manufacturing." In March 1997, our subsidiary in the automatic call
distribution products business was spun off to the Cortelco Systems Holding
Corporation shareholders, merged with Business Communications Systems, Inc.,
and renamed "BCS Technologies, Inc."
 
In April 1999:
 
    . Cortelco Systems Holding Corporation distributed its shares of
      Cortelco common stock in a spin-off transaction
 
    . we merged with Cortelco Systems Puerto Rico, Inc., another subsidiary
      of Cortelco Systems Holding Corporation, in exchange for 553,880
      shares
 
    . we acquired BCS in exchange for 3,969,681 shares
 
BCS and Cortelco Systems Puerto Rico are now wholly-owned subsidiaries of
Cortelco.

                                Use of Proceeds
 
Our net proceeds from the sale of the     shares of common stock offered by us
are estimated to be approximately $     or approximately $     if the
underwriters exercise the over-allotment option in full, after deducting
underwriting discounts and commissions and estimated offering expenses payable
by us. We will not receive any proceeds from the sale of common stock by the
selling stockholders.
 
We currently intend to use our net proceeds from this offering:
 
    . to fully repay a $2.3 million long-term subordinated note with
      ChinaVest IV, L.P. that accrues interest at an 8.0% annual rate and
      matures on July 2002
 
    . to fully repay $2.0 million of senior debt under two credit facilities
      with Foothill Capital, one of which accrues interest at a rate equal
      to the prime rate plus .375% and matures in July 2001, and the other
      of which accrues interest at a rate equal to the prime rate plus 1.25%
      and matures on August 2001
 
    . for working capital and general corporate purposes
 
We may also use some of the proceeds to acquire other companies, technologies
or products that complement our business, although we have not yet developed
any plans regarding these transactions. Pending use of the net proceeds as
described above, we intend to invest the net proceeds from this offering in

                                Dividend Policy
 
We have declared cash dividends in the past in connection with intercompany
financing transactions with our parent company. See "Certain Transactions."
Cortelco currently anticipates that it will retain earnings to support
operations and finance the growth and development of its business and does not
anticipate declaring cash dividends for the foreseeable future. Future
dividends, if any, will be at the discretion of the board of directors, which
will base its decision on a number of factors, including our operating results
and financial requirements. The terms of our senior debt, which will be repaid
from the proceeds of this offering, prohibit the declaration and payment of
dividends without the approval of the lender.

                                    Dilution
 
Our pro forma net tangible book value at January 31, 1999 was approximately
$5.0 million, or $0.65 per share of common stock. Pro forma net tangible book
value per share represents the amount of total assets, less: (1) goodwill and
identifiable intangible assets, (2) total liabilities and (3) preferred stock,
divided by the number of outstanding shares of common stock. After giving
effect to the sale of     shares of common stock offered to new investors by
Cortelco at an assumed initial public offering price of $    per share, and
after deducting underwriting discounts and commissions and estimated offering
expenses, our pro forma net tangible book value at January 31, 1999 would have
been approximately $   , or $    per share. This represents an immediate
increase in pro forma net tangible book value of $    per share to existing
stockholders and an immediate dilution in net tangible book value of $    per
share to new investors. The following table illustrates the per share dilution:

                 Selected Pro Forma Consolidated Financial Data
 
The following pro forma consolidated statements of operations data for the year
ended July 31, 1998 and the six months ended January 31, 1998 and 1999
represent the unaudited pro forma operating results as if the acquisition of
BCS had occurred as of August 1, 1997. The pro forma financial data reflects
adjustments to our consolidated financial statements that (1) reflect the
purchase method of accounting for the acquisition of BCS and (2) eliminate the
results of operations and related assets and liabilities not acquired from the
merger with Cortelco Systems Puerto Rico.
 
The pro forma financial data does not purport to represent what our results of
operations actually would have been had the transactions occurred on the dates
indicated, or to project our results of operations at any future date or for
any future period. The following pro forma financial data should be read in
conjunction with Cortelco's consolidated financial statements and related
notes, BCS' consolidated financial statements and related notes and the
Unaudited Pro Forma Consolidated Financial Information and related notes, all
of which are included elsewhere in this prospectus, and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                      Selected Consolidated Financial Data
 
The selected consolidated financial data represent the results of Cortelco
Systems Puerto Rico and Cortelco and do not reflect the operating results of
BCS or the pro forma adjusting entries for the acquisition of BCS by Cortelco
in April 1999. The statement of operations data set forth below for each of the
fiscal years ended July 31, 1996, 1997 and 1998, and the selected balance sheet
data at July 31, 1997 and 1998, are derived from consolidated financial
statements audited by Deloitte & Touche LLP, independent auditors, whose
reports appear elsewhere in this prospectus. The consolidated balance sheet
data at July 31, 1996 is derived from audited financial statements not included
in this prospectus. The statement of operations data for the six months ended
January 31, 1998 and 1999 and the year ended July 31, 1995 and the balance
sheet data as of July 31, 1995 are derived from unaudited financial statements.
However, in the opinion of management, the selected financial data for such
periods include all adjustments, which include only normal recurring
adjustments, necessary for a fair presentation of the data. This data should be
read in conjunction with our consolidated financial statements and notes
thereto appearing elsewhere in this prospectus and "Management Discussion and
Analysis of Financial Condition and Results of Operations." The results of
operations for the six months ended January 31, 1999 are not necessarily
indicative of the results to be expected for the full year.

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations
 
The following discussion of our results of operations and financial condition
should be read in conjunction with the consolidated financial statements and
related notes and other financial information included elsewhere in this
prospectus. This discussion contains forward-looking statements that involve
risks and uncertainties. Our actual results may be materially different from
those anticipated in these forward-looking statements as a result of certain
factors, including, but not limited to, those set forth under "Risk Factors"
and elsewhere in this prospectus.
 
Overview
 
Cortelco designs, develops and markets integrated enterprise communications
systems for routing and controlling the voice, video and data communications of
businesses and other organizations. Our solutions are primarily designed for
small and medium-sized telephony installations in a range of vertical markets
such as education, retail, government agencies, emergency-911 services and
catalog sales. Our operations are conducted through three business units:
Systems Business Operations, ACD Business Operations and Caribbean and Latin
American Operations. The Systems Business Operations unit primarily focuses on
the Millennium product line. The ACD Business Operations unit primarily focuses
on the DSP Series product line. The Caribbean and Latin American Operations
unit currently distributes the Millennium and DSP Series systems and resells
cellular airtime, cellular telephones and third-party voice communications
systems in Puerto Rico.
 
In April 1999, Cortelco merged with its sister company, Cortelco Systems Puerto
Rico, which became the Caribbean and Latin American Operations unit, and
acquired BCS, which became the ACD Business Operations unit. Prior to April
1999, our three business units shared substantial common ownership and prior to
March 1997 had been part of the same corporate family. See "Company
Background." Cortelco and Cortelco Systems Puerto Rico had previously been
subsidiaries of Cortelco Systems Holding Corporation. As a result, the merger
of Cortelco and Cortelco Systems Puerto Rico has been recorded for all periods
presented at historical costs and the financial statements are presented on a
consolidated basis for all historical periods. BCS had previously been
partially owned by certain stockholders of Cortelco. As a result, the
acquisition of BCS has been accounted for using the purchase method of
accounting for the portion of BCS not owned through common ownership prior to
the acquisition and using historical costs for the portion of BCS that was
owned through common ownership prior to the acquisition. Goodwill in the amount
of $5.2 million was recorded in the BCS acquisition and is being amortized over
20 years.
 
Our revenues are primarily derived from our sale of Millennium and DSP Series
systems, related systems products and services and the resale of cellular
airtime, cellular telephones and third-party voice communications systems in
Puerto Rico. Revenue is recognized upon shipment of product to our dealers and
end-user customers for Millennium systems and third-party systems, and upon
acceptance for DSP Series systems due to the customized nature of each
installation. In addition, our Caribbean and Latin American Operations unit
generates revenue from the resale of cellular airtime and cellular telephones
in Puerto Rico and recognizes these revenues when earned. Typical selling
prices range from $22,000 to $36,000 for Millennium systems and $75,000 to
$230,000 for DSP Series systems, depending on the system configuration. For the
six months ended January 31, 1999, on a pro forma basis, we generated
approximately 46% of our revenue from the sale of Millennium products and
approximately 31% from the sale of DSP Series products. Pro forma revenues
increased 36.9% from $17.7 million for the six months ended January 31, 1998 to
$24.2 million for the six months ended January 31, 1999.
 
In the past several years, we have undergone some significant changes. In
fiscal 1994, we introduced a new digital platform, the Millennium, to replace
an older analog product, which was ultimately discontinued in fiscal 1998.
During fiscal 1996 and fiscal 1997, we sold a substantial number of Millennium
systems to a single customer for installations in Southeast Asia. This customer
ceased placing new orders with us in 1997 due to general economic instability
in Southeast Asia, which resulted in a $2.4 million decrease in purchases by
this customer in fiscal 1998 as compared to fiscal 1997. Moreover, in fiscal
1997, Cortelco Systems Puerto Rico redirected its marketing of cellular airtime
and cellular telephones to focus on higher quality customers, mainly
businesses, in order to minimize credit losses and increase margins. This
resulted in a reduction of Cortelco Systems Puerto Rico's revenues from the
resale of cellular airtime and cellular telephones from $9.8 million in fiscal
1997 to $6.7 million in fiscal 1998. Beginning in the second quarter of fiscal
1998, Cortelco, under the leadership of a new president, refocused its overall
marketing strategy and began to target markets for which the Millennium system
is particularly well-suited. Product development programs have been directed to
new software and other initiatives to strengthen the Millennium product line
and increase gross margins. We also increased our sales staff and expanded our
dealer and value added reseller network. As a result of these changes and
programs, Cortelco has become profitable and our operating results have
continued to improve in recent quarters.

Pro Forma Results of Operations
 
As a result of the recent acquisition of BCS, our historical financial
statements for past periods do not accurately reflect our current results of
operations. We have therefore included the results of operations on a pro forma
basis so that you can better understand our business. The following tables
present the pro forma results for the three months ended October 31, 1997 and
1998 and January 31, 1998 and 1999 as if the acquisition of BCS had occurred as
of August 1, 1997. We believe that all necessary adjustments, consisting of
only normal recurring adjustments, have been included in the amounts stated
below. The pro forma financial data are presented for illustrative purposes
only and do not purport to represent what our results of operations actually
would have been had the transactions occurred on the dates indicated, or to
project our results of operations for any future period. This data should be
read in conjunction with the Unaudited Pro Forma Consolidated Financial
Information and the related notes, our consolidated financial statements and
the related notes and BCS' financial statements and the related notes, all of
which are included elsewhere in this prospectus.

determination of shares used in computing basic and diluted pro forma net
income (loss) per share.
 
Quarterly results of operations, in particular the quarters ended October 31
and January 31, are likely to fluctuate due to a number of factors, including
seasonal factors that affect customers in some of our vertical markets. For
example, U.S. government customers typically make substantial purchases during
the quarter ended October 31, the last quarter of the government's fiscal year,
and these purchases decline significantly in the next quarter. Customers in
other vertical markets such as education and retail have also exhibited
seasonal buying patterns and do not purchase substantial amounts of equipment
during the quarter ended January 31. As a result, revenues in the quarter ended
January 31 are often lower than in the previous quarter. The uncertainty of our
sales cycle also makes the timing of sales difficult to predict and may cause
fluctuations in our quarterly results of operations. The purchase of our
products may involve a significant commitment of our customers' personnel,
financial and other resources to conduct technical evaluations, to support
installation and training and to fund purchases. As a result, our sales cycles
vary from one to six months for Millennium systems and from four to twelve
months for the DSP Series systems. See "Risk Factors--Our Quarterly Operating
Results May Fluctuate."
 
                                       16

 
Revenues. Our revenues are primarily derived from the sales of Millennium and
DSP Series systems, related systems products and services and the resale of
cellular airtime, cellular telephones and third-party voice communications
systems in Puerto Rico. Our pro forma quarterly revenues have increased over
the prior year for the quarters ended October 31, 1998 and January 31, 1999 due
primarily to the FAA contract, enhancements of our product line and expansion
of our sales force. Systems revenue from sales of third-party voice
communications systems in Puerto Rico generally account for approximately 5% to
10% of pro forma total revenues in each quarter. Our pro forma cellular airtime
and cellular telephone revenues have generally decreased as a percentage of
total revenues since the quarter ended October 1997, primarily due to our
limiting sales activities to higher quality customers, and were 10.5% of pro
forma revenues for the quarter ended January 31, 1999. Our pro forma revenues
for the quarters ended January 31, 1998 and 1999 have been influenced by
seasonal buying patterns in some of our vertical markets. Consequently, pro
forma revenues are lower in the quarters ended January 31 than in the quarters
ended October 31. Furthermore, our revenues were adversely affected in the
first half of 1998 due to a decrease in orders from our single largest customer
due to general economic instability in Southeast Asia and the unexpected loss
of a key sales executive. Pro forma revenues reflect purchases by the FAA of
$2.6 million and $2.6 million for the last two quarters ended January 31, 1999
under a contract scheduled to expire in April 1999. Although revenues from the
U.S. government are likely to decline after April 1999 due to the completion of
installations under the FAA contract, we expect U.S. government agencies to
continue to account for a significant portion of our systems revenue. See "Risk
Factors--Our Recent Results Have Been Affected by One Large Customer."
 
Pro forma revenues increased 36.9% from $17.7 million for the six months ended
January 31, 1998 to $24.2 million for the six months ended January 31, 1999.
The increase was primarily due to $5.2 million in purchases of DSP Series
systems by the FAA and an increase in Millennium revenues of $2.3 million,
partially offset by a decrease in cellular revenues of $0.7 million. Millennium
systems sales increased primarily due to the expansion of our sales force and
the introduction of new product features during the last year, while cellular
revenues decreased during the period due primarily to our decision to target
higher quality customers. For the six months ended January 31, 1999, the FAA
accounted for 21.5% of our total pro forma revenues.
 
Cost of Revenues and Gross Profit. Cost of revenues consists primarily of
purchases from our contract manufacturers and other suppliers. Lower pro forma
gross profit in the quarters ended January 31, 1998 and 1999 were due primarily
to seasonal declines in revenues caused by our customers' purchasing cycles.
Pro forma gross profit increased in year over year comparative quarters due
primarily to higher revenues and a change in product mix in favor of higher
margin products, primarily DSP Series systems.
 
Pro forma gross profit increased 55.8% from $7.7 million for the six months
ended January 31, 1998 to $12.1 million for the six months ended January 31,
1999. The increase was primarily due to an increase in DSP Series gross profit
from $1.6 million for the six months ended January 31, 1998 to $5.0 million for
the six months ended January 31, 1999. Millennium systems gross profit
increased from $4.6 million for the six months ended January 31, 1998 to $6.3
million for the six months ended January 31, 1999 due primarily to higher
revenues. Gross profit from the resale of cellular airtime and cellular
telephones decreased from $1.1 million for the six months ended January 31,
1998 to $0.9 million for the six months ended January 31, 1999 due primarily to
lower cellular revenues. Pro forma gross margin increased from 43.8% for the
six months ended January 31, 1998 to 49.8% for the six months ended January 31,
1999 due primarily to the increase in DSP Series revenues and an increase in
gross margin for the DSP Series from 62.0% of DSP Series revenues for the six
months ended January 31, 1998 to 65.0% of DSP Series revenues for the six
months ended January 31, 1999.
 
Selling, General and Administrative. Selling, general and administrative
expenses consist primarily of salaries and benefit costs, advertising and trade
show related costs, and facilities and other overhead expenses incurred to
support the growth of our business. Costs incurred for final assembly, quality
assurance and installation of our systems are included as selling, general and
administrative expenses instead of cost of revenues. Selling, general and
administrative expenses generally increased in connection with the growth of
our business. We expect selling, general and administrative expenses to
increase as we invest in new sales and service personnel, however, we
anticipate that these expenses will decrease as a percentage of revenues in
future periods.
 
Pro forma selling, general and administrative expenses increased from $6.7
million for the six months ended January 31, 1998 to $7.4 million for the six
months ended January 31, 1999. The increased expense was due primarily to the
growth of the business and the hiring of additional sales personnel. These
expenses as a percentage of pro forma revenues decreased from 38.0% for the six
months ended January 31, 1998 to 30.5% for the six months ended January 31,
1999.
 
                                       17

 
Research and Development. Research and development expenses consist primarily
of personnel and related expenses for our engineering staff and depreciation of
related equipment. Research and development expenses generally increased since
the quarter ended October 1997 due primarily to the hiring of additional
engineering personnel. We expect research and development expenses to continue
to increase in dollars and as a percentage of revenues in future periods as we
hire additional engineers to support our new product initiatives.
 
Pro forma research and development expenses increased from $1.0 million for the
six months ended January 31, 1998 to $1.6 million for the six months ended
January 31, 1999. The increased expense was due primarily to the hiring of
additional engineering personnel as well as additional equipment purchases.
These expenses as a percentage of pro forma revenues increased from 5.9% for
the six months ended January 31, 1998 to 6.5% for the six months ended January
31, 1999.
 
Amortization of Goodwill. Cortelco recorded $5.2 million of goodwill related to
the acquisition of BCS in April 1999 for the portion of BCS not previously
owned through common ownership. We are amortizing the goodwill over a 20-year
period from the date of acquisition and have reflected the amortization as
though the transaction was effective August 1, 1997 for purposes of our pro
forma presentation in the consolidated statement of operations data.
 
Management Fee. Management fee expense (income) consists primarily of
administrative expenses incurred by, or provided to, our former parent company
related to administrative services.
 
Minority Interest. Minority interest represents the minority stockholder's 45%
share of income in Longhai Telecommunications Equipment Co., Ltd. in China.
Cortelco acquired a 55% interest in Longhai in August 1997. Cortelco does not
currently anticipate investing in additional joint ventures in China. See note
9 to our consolidated financial statements.
 
Historical Results of Operations of Cortelco and Cortelco Systems Puerto Rico
 
Cortelco Systems Puerto Rico was merged with Cortelco in April 1999 and has
been recorded for all periods presented at historical costs and the financial
statements are presented on a consolidated basis for all historical periods. As
a result, the historical results of operations for the six months ended January
31, 1998 and 1999 and the fiscal years ended July 31, 1996, 1997 and 1998
represent the results of Cortelco Systems Puerto Rico and Cortelco and do not
reflect any of the operating results of BCS, or the pro forma adjusting entries
for the acquisition of BCS by Cortelco in April 1999.
 
Six Months Ended January 31, 1998 and 1999
 
Revenues. Total revenues increased 14.3% from $15.3 million for the six months
ended January 31, 1998 to $17.5 million for the six months ended January 31,
1999. The increase resulted primarily from increased sales of Millennium
systems to the U.S. government, increased sales of Cortelco Voice Processing
Systems and increased sales of third-party equipment in Puerto Rico. These
increases were partially offset by decreases in cellular airtime and cellular
telephone revenues in Puerto Rico in an effort to target higher quality
customers.
 
Cost of Revenues and Gross Profit. Gross profit increased 16.6% from $6.2
million for the six months ended January 31, 1998 to $7.2 million for the six
months ended January 31, 1999. The increase in gross profit was due primarily
to the growth in revenues. The gross margin was 40.2% for the six months ended
January 31, 1998 and 41.0% for the six months ended January 31, 1999.
 
Operating Expenses. Operating expenses increased 5.6% from $6.2 million for the
six months ended January 31, 1998 to $6.1 million for the six months ended
January 31, 1999. The increase was due primarily to the hiring of additional
engineering and sales personnel during the period. Operating expenses decreased
as a percentage of revenues from 38.1% for the six months ended January 31,
1998 to 35.0% for the six months ended January 31, 1999.
 
Years Ended July 31, 1996, 1997 and 1998
 
Revenues. Revenues were $38.5 million for the year ended July 31, 1996, $35.6
million for the year ended July 31, 1997 and $30.9 million for the year ended
July 31, 1998. The decrease from fiscal 1996 to fiscal 1997 resulted primarily
from phasing out our older analog product and decreases in cellular airtime and
cellular telephone revenues in Puerto Rico. The decrease from fiscal 1997 to
fiscal 1998 was due primarily to the decrease in cellular airtime and cellular
telephone revenues resulting from our decision to target higher quality
customers, the decrease in orders from our single largest customer due to
general economic instability in Southeast Asia, and the discontinuance of our
older analog product in fiscal 1998.

Cost of Revenues and Gross Profit. Gross profit was $11.8 million for the year
ended July 31, 1996, $11.5 million for the year ended July 31, 1997 and $12.4
million for the year ended July 31, 1998. The decrease in gross profit from
fiscal 1996 to fiscal 1997 was due primarily to the decrease in revenues. The
increase in gross profit from fiscal 1997 to fiscal 1998 was due primarily to
the increased sale of higher margin Millennium products such as the Cortelco
Voice Processing System. Gross margin was 30.6% for the year ended July 31,
1996, 32.2% for the year ended July 31, 1997, and 40.2% for the year ended July
31, 1998.
 
Operating Expenses. Operating expenses were $9.1 million for the year ended
July 31, 1996, $11.4 million for the year ended July 31, 1997 and $11.5 million
for the year ended July 31, 1998. Research and development expenses increased
during the periods due mainly to hiring of additional engineering personnel,
while selling, general and administrative expenses decreased during the year
ended July 31, 1998 due primarily to a decrease in administrative expenses
associated with the decreased cellular airtime and cellular telephone sales
during the year.
 
Discontinued Operations. Discontinued operations represent the results of
operations of a former subsidiary of Cortelco that was spun off in March 1997
to the stockholders of our former parent, merged with Business Communications
Systems, Inc. and renamed "BCS Technologies, Inc." At the time of spin-off, the
subsidiary had experienced substantial net losses and our former parent decided
to concentrate its focus on realizing the Millennium's business potential.
 
Liquidity and Capital Resources
 
We have funded our operations primarily through cash generated from operations,
periodic borrowings under our existing credit facilities, a $3.0 million
subordinated convertible note financing and acquisition financing provided by
Alcatel in connection with the purchase of our business from Alcatel in 1990.
 
Net cash provided by operating activities was $1.6 million for the year ended
July 31, 1996, $1.1 million for the year ended July 31, 1997, $1.1 million for
the year ended July 31, 1998, $1.3 million for the six months ended January 31,
1998 and $0.9 million for the six months ended January 31, 1999. Cash provided
by operating activities in fiscal 1997 and fiscal 1998 primarily resulted from
improved collection procedures implemented during these years. The decrease in
cash provided by operating activities for the six months ended January 31, 1999
was primarily attributable to increased accounts receivable, partially offset
by increased net income, decreased inventories and increased accounts payable.
 
Net cash used in investing activities was $0.5 million for the year ended July
31, 1996, $0.9 million for the year ended July 31, 1997, $0.2 million for the
year ended July 31, 1998, $0.2 million for the six months ended January 31,
1998 and $0.3 million for the six months ended January 31, 1999. In each year,
cash used in investing activities was primarily attributable to purchases of
equipment and, in fiscal 1997, to purchases of in-process technology. To the
extent that we continue to grow our research and development activities and
invest in new technologies in the future, we expect net cash used in investing
activities will increase.
 
Net cash used in financing activities was $1.1 million for the year ended July
31, 1996, $0.2 million for the year ended July 31, 1997, $1.1 million for the
year ended July 31, 1998, $1.3 million for the six months ended January 31,
1998 and $0.6 million for the six months ended January 31, 1999. Cash used in
financing activities in the year ended July 31, 1998 consisted primarily of a
decrease in outstanding checks, repayments under the revolving credit line and
partial repayment of a note to our former parent company, Cortelco Systems
Holding Corporation. The primary source of cash from financing activities in
the year ended July 31, 1997 was a $3.0 million subordinated convertible note
financing. See "Certain Transactions."
 
In July and August 1997, we entered into two credit facilities with Foothill
Capital which allows us to borrow up to an aggregate $9.0 million based on
accounts receivable and inventory levels. See note 11 to our consolidated
financial statements.
 
We believe that the proceeds from this offering, together with available funds,
anticipated cash flows from operations and our line of credit, will satisfy our
projected working capital and capital expenditure requirements for the
foreseeable future. To the extent that we grow more rapidly than expected in
the future, we may need additional cash to finance our operating and investing
activities.

Year 2000 Compliance
 
The Year 2000 issue is the result of computer programs written using two
digits rather than four to define the applicable year (the "Year 2000 Issue").
Computer programs that have such date-sensitive software may recognize a date
using "00" as the Year 1900 rather than the Year 2000. This could result in a
system failure or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process transactions,
send invoices or engage in similar normal business activities.
 
We are heavily dependent upon the proper functioning of our own computer or
data-dependent systems. This includes, but is not limited to, our systems in
information, business, finance, operations and service. Any failure or
malfunctioning on the part of these or other systems could adversely affect us
in ways that are not currently known, discernible, quantifiable or otherwise
anticipated by us.
 
Our operations are also dependent on the Year 2000 readiness of third parties
that do business with us. We are dependent on third-party suppliers of
infrastructure elements such as electric power and banking facilities. We do
not depend to any significant degree upon electronic transaction processing
with individual vendors for merchandise purchases, however, many of our
customers pay their invoices via electronic payment.
 
We have begun to evaluate those areas of our business that may be affected by
the Year 2000 Issue and have devised a plan to become Year 2000 compliant in a
timely manner which includes:
 
    . assessment of our own computer systems and the products we sell
 
    . communications with all our key suppliers, manufacturers and customers
      to determine the extent to which we are vulnerable to their failure to
      remedy their own Year 2000 Issues
 
    . correction, upgrade, replacement or retirement of our computer systems
      which are affected by the Year 2000 Issue
 
    . testing for and validation of our Year 2000 compliance
 
    . development of contingency plans to address situations that may result
      if we are unable to achieve Year 2000 compliance of our critical
      operations
 
Based on our assessment to date, we have determined that we will be required
to upgrade a portion of our software so that our computer systems will
function properly with respect to dates in the Year 2000 and thereafter. We
estimate that our information systems will be Year 2000 compliant by July
1999. We estimate that costs associated with the upgrade of existing computer
software will be less than $75,000. Costs incurred and expensed in the six
months ended January 31, 1999 were less than $25,000. These costs related
entirely to modifications of existing software and represented approximately
10% of our information systems budget for information technology in the
period. Of the remaining portion of our estimated Year 2000 costs,
approximately $30,000 of the costs will be incurred in the fiscal quarter
ending July 31, 1999. We may address non-critical Year 2000 Issues beyond the
Year 2000. There is no assurance that total costs will not exceed our
estimates.
 
We are in communications with key suppliers, manufacturers and customers to
determine the extent to which we will be vulnerable to such parties' failure
to remedy their own Year 2000 Issues. We currently have only limited
information on the Year 2000 compliance of our key suppliers, manufacturers
and customers. Our business and results of operations could experience
material adverse effects if our key suppliers or manufacturers were to
experience Year 2000 Issues that caused them to delay production or shipment
of key components or systems. In addition, our results of operations could be
materially adversely affected if any of our key customers encounter Year 2000
Issues that cause them to delay or cancel substantial purchase orders or
delivery of our product.
 
There can be no assurance that we will be able to upgrade any or all of our
major systems in accordance with our plan to address the Year 2000 Issue. In
addition, there can be no assurance that any such upgrades will effectively
address the Year 2000 Issue. If required upgrades are not completed or are
unsuccessful, there would be a material adverse impact on our operations.
Furthermore, there can be no guarantee that the systems of other companies on
which our own systems rely will be timely converted, or that a failure to
convert by another company, or a conversion that is incompatible with our
systems, would not have a material adverse effect on us. We intend to, but
have not yet established a contingency plan detailing actions that will be
taken in the event that the assessment of the Year 2000 Issue is not
successfully completed on a timely basis. We believe that the worst case Year
2000 scenario would involve disruption in utilities, transportation, and
banking facilities.

                                    Business
 
Cortelco designs, develops and markets integrated enterprise communications
systems for routing and controlling the voice, video and data communications of
businesses and other organizations. Our solutions are primarily designed for
enterprises with complex communications needs and small and medium-sized
telephony installations, typically between 25 to 500 communications ports. We
serve a range of vertical markets such as education, retail, government
agencies, emergency-911 services and catalog sales. Some of our customers have
multiple installations networked together and are as large as national retail
chains or multi-location branches of the U.S. government. Our customers include
Circuit City, U-Haul, the FAA, Bell Atlantic and Budget Rent-A-Car. Our
products are installed in over 7,100 locations worldwide. In addition to
selling our products, we also resell cellular airtime, cellular telephones and
third-party voice communications systems in Puerto Rico. Our products have won
numerous awards, including "Best of Show" awards at CT Expo in 1997 and 1998
and "Product of the Year" awards in 1997 and 1998 from Call Center magazine and
in 1999 from Call Center Solutions magazine. On a pro forma basis, our revenues
increased 36.9% from $17.7 million for the six months ended January 31, 1998 to
$24.2 million for the six months ended January 31, 1999.
 
Our communications systems are based on two platforms, the Millennium and the
DSP Series. Both platforms are based on flexible, modular hardware and software
architectures that are easy to configure. Our platforms support multi-site
networking and other advanced features such as dynamic call routing,
interactive voice response, voicemail and computer telephony integration. The
Millennium is a full-function routing and control system that primarily serves
customers averaging approximately 110 communications ports per installation and
addresses a broad range of voice, video and data communications requirements.
The Millennium also includes automatic call distribution features. The DSP
Series is primarily an advanced automatic call distribution system that also
includes a full-function routing and control system. The DSP Series is
typically used in installations requiring advanced computer telephony
integration applications such as those used in sophisticated call centers. The
architecture of our platforms is designed to permit easy configuration and
subsequent upgrading to meet changing customer needs. Customer desired features
can be incorporated through the installation of optional add-in cards and
software. Millennium systems can be connected over the public service telephone
network or private data networks and can support ISDN based systems such as
videoconferencing. Both the Millennium and the DSP Series interface with a
variety of popular third-party products through standard protocols.
 
We also offer other products to provide our customers with cost-effective,
integrated communications solutions. For example, the Cortelco Voice Processing
System offers integrated, multi-lingual voice and fax messaging services across
multiple networked locations. Our Illuminations software package enables self-
service access to databases, such as product pricing information or school
course registration options, using touch-tone telephones or the Internet. We
also offer software that organizes call center data into real-time,
customizable, graphical user interfaces and reports for agents and supervisors.
 
Industry Overview
 
According to Dataquest, the U.S. private branch exchange and call center
systems markets totaled $5.7 billion in 1998. Traditionally, the voice
switching requirements of large enterprises have been addressed by private
branch exchange equipment. Enterprises with smaller installations that have not
been able to justify the expense of private branch exchange equipment have
utilized key telephone systems that, while more economical, have limited
functionality and scalability. Technology advances and the demands of
increasingly sophisticated customers are driving changes in today's
telecommunications equipment industry. Businesses and organizations have come
to rely on complex voice and data networks to meet mission critical needs.
Recent technology advances have resulted in the introduction of increasingly
sophisticated features and applications in enterprise communications systems
that extend beyond traditional voice switching. Enterprises of all sizes are
now demanding telecommunications systems with the latest features and
applications in order to meet their business objectives. These features include
dynamic call routing, computer telephony integration, support for the
convergence of voice and data networks, multi-site networking and mobile
workforce support.
 
Dynamic Call Routing
 
Advanced call routing capabilities have recently been introduced that
dynamically screen, distribute and queue incoming calls based on specific
caller information, such as the number dialed or the state from which the call
is made. The growing number of "1-800" and "1-900" mail order, e-commerce and
customer support centers, driven by a focus on customer service, is generating
increased demand for dynamic call routing capabilities. These capabilities,
originally available only in dedicated automatic call distribution systems for
large stand-alone call centers, are now available as optional features on
 
                                       21

 
standard private branch exchange equipment, and are being used for more general
business applications in various departments, such as human resources and
customer support.
 
Computer Telephony Integration
 
Computer telephony integration is the combination of voice communication and
computing capabilities which link telephony equipment to voicemail servers,
telephone directories, customer information databases and PC applications.
Enterprises increasingly seek voice communications systems that can use
standard protocols to interface with numerous third-party computer
applications. Such integrated applications include interactive voice response,
call accounting and unified messaging. For example, computer telephony
integration applications can be used to personalize call handling based on a
customer database and other information provided from the business' data
network. When an incoming call is connected to the customer service agent,
pertinent information concerning the particular caller can be displayed on the
agent's monitor, enabling the agent to provide a prompt and informed response
to the customer.
 
Convergence of Voice and Data Networks
 
Advances in networking and computing technologies offer the prospect of
combining voice and data networks which until now have been built and operated
as separate networks. The ability to combine separate voice and data networks
into one converged network could improve functionality, reduce network
administration and provide cost savings. For example, the widespread
implementation of IP based data networks has led to the development of voice-
over-IP technology that permits transmission of voice communications over
public or private IP networks. According to Dataquest, transmission of voice
traffic over IP networks in smaller enterprises is projected to grow at a
compound annual growth rate of 313% to 18.8 billion minutes of use in 2000.
 
Multi-Site Networking
 
Enterprises are increasingly dependent on distributed voice and data networks
to support their operations across multiple locations. A networked voice
communications solution delivers voice communication functions across multiple
locations as an integrated system, thereby increasing productivity and user
convenience and reducing costs. For example, messaging can be centralized so
that voicemail, e-mail and faxes can be delivered seamlessly to all locations
across the network.
 
Support for a Mobile Workforce
 
Today's work environment is characterized by the need for real-time
communications that support increasingly mobile workers. Employees need to have
access to, and be accessible through, the enterprise's communications network
to make informed decisions quickly, improve productivity and respond to
customer needs rapidly. InfoTech Consulting estimates that the market for in-
building and campus wireless communications will grow by 67% from 2.4 million
users in 1999 to 4.0 million users in 2000. Remote access capabilities also
allow off-site workers to access all functions of the enterprise's
communications system as if they were on-site.
 
Traditional voice communications systems were designed to provide a broad range
of capabilities, but were not designed to be readily adaptable. Implementing
new features and applications on these systems often requires substantial
development effort and the purchase of ancillary equipment. Further
customization may be necessary to meet the needs of a particular installation.
Given the expense of ancillary equipment and customized development and the
need to allocate development resources to support larger customers,
communications systems vendors have generally addressed the small to medium-
sized installation segment of the market with equipment that is often costly
and less flexible. Thus, while traditional private branch exchange systems have
been able to adapt to the changing needs of large installations, the complexity
of these systems has limited the ability of traditional vendors to provide
flexible and cost-effective communications solutions for small and medium-sized
installations.
 
                                       22

 
The Cortelco Solution
 
Cortelco provides integrated communications systems flexible enough to meet the
immediate needs of enterprises with small to medium-sized installations, yet
scalable enough to accommodate these businesses and organizations as they grow.
Our systems are based on a general purpose bus architecture designed from the
outset to permit the dynamic addition and variation of inputs, outputs and
features through software and configuration of the system through add-in cards.
Our solution offers functionality previously not readily available or cost-
effective for small to medium-sized installations. Our communications platforms
provide advanced features at an affordable cost and without the need for
extensive specialized software and hardware or complex installation procedures.
 
The flexible architecture of our Millennium and DSP Series platforms is the
backbone for all of our products. Our comprehensive solutions are designed to
improve the productivity and efficiency of our customers by providing them with
a variety of communications capabilities, such as:
 
    . advanced call routing allowing for dynamic distribution of incoming
      voice, video and data traffic
 
    . easy integration of voice communications and computing capabilities
 
    . cost-effective multi-site networking
 
    . advanced mobility features to provide in-building and campus wireless
      communications and remote access by off-site workers
 
We believe that we have achieved significant advantages in the configurability
of and the ease of programming these capabilities and other new features
relative to many competitors. Our flexible core platforms and range of options
offer enterprises with small to medium-sized installations the combination of
features and functions that best suit their particular needs.
 
Strategy
 
Cortelco's objective is to provide comprehensive, cost-effective communications
systems for small and medium-sized installations in selected vertical markets.
Our strategy incorporates the following key elements:
 
Target Small to Medium-Sized Installations
 
We target enterprises with small to medium-sized installations, typically 25 to
500 communications ports, at one or more locations and that may have complex
communications needs. We focus our sales efforts on selected vertical markets
in which we have identified needs that can be especially well served by our
systems and are characterized by enterprises with small to medium-sized
installations, complex communications needs and cost-sensitivity. Our current
targeted vertical markets include education, retail, government agencies,
emergency-911 services and catalog sales. The inherent flexibility and
configurability of our Millennium and DSP Series platforms make us uniquely
suited to meet the needs of our targeted customers.
 
Provide Cost-Effective, Integrated Customer Solutions
 
We provide customers with cost-effective, integrated solutions for their voice
communications requirements, including solutions to seamlessly integrate their
voice and data networks. We believe our customers prefer to purchase integrated
solutions from a single vendor due to convenience, consistency of service, ease
of upgrade and vendor accountability. We offer an integrated family of
communications products that interface with a wide range of third-party
products through industry standard protocols, enabling us and our dealers to
configure and deliver complete, customized voice communications systems that
meet the specific needs of each customer.
 
Expand Distribution Capabilities
 
We are expanding both our direct sales force and our dealer network to more
aggressively pursue our target markets. Since March 31, 1998, we have increased
our sales force by approximately 48% from 25 to 37 and we plan further
increases over the next year. We believe our use of indirect sales channels is
especially effective because our dealers often have experience in our targeted
vertical markets and because our flexible platforms enable them to sell,
configure and service advanced features with relatively little expertise. As of
March 31, 1999, we had approximately 130 authorized dealers and value added
resellers. We are also expanding our geographic coverage by recruiting new
dealers, value added resellers and strategic partners in the United States, the
Caribbean and Latin America.
 
 
                                       23

 
Develop New Product Capabilities
 
We intend to continue to enhance our core product line and develop new features
and applications that leverage our existing Millennium and DSP Series
platforms, address emerging market needs and increase gross margins. For
example, we recently introduced new features and applications such as circuit
switched data capabilities for data intensive applications and PC-based phone
control. We expect to introduce several additional product capabilities during
1999, including:
 
    . integrated in-building and campus wireless capabilities which increase
      the range and maximum number of users on the existing Orbit Wireless
      Communications product and add desktop equivalent capabilities
 
    . unified messaging which provides integrated access to voice, fax and
      e-mail messages in a multi-site networked communications system
 
    . IP capabilities such as voice-over-IP, virtual private networks for
      voice and data applications and other Internet-based applications
 
    . Web-based virtual call center capabilities allowing agents and
      supervisors located anywhere in the world to access their call centers
      over the Internet
 
We are also developing our next generation automatic call distribution and
switching architecture to address the integration of emerging voice and data
communications technologies.
 
Products and Services
 
Cortelco offers the Millennium and the DSP Series, two feature-rich
communications platforms targeted at specific market segments. Each platform
provides advanced features that are easy to program and cost-effective due to
an innovative modular hardware design and flexible software. Both platforms
support multi-site networking and advanced features such as dynamic call
routing, interactive voice response, voicemail and computer telephony
integration. Our platforms share a suite of applications and hardware,
including voice processing systems, an in-building and campus wireless
communications system, a number of advanced computer telephony integration
products and digital handsets. Both platforms also interface to a range of
popular third-party products through standard protocols. These two
communications systems allow us to provide an integrated communications
solution for our target markets.
 
We also sell a variety of other products for use with our platforms. Our
Caribbean and Latin American Operations unit sells communications systems and
products produced by Cortelco and resells cellular airtime, cellular telephones
and third-party voice communications systems in Puerto Rico.
 
The Millennium
 
The Millennium is a fully-featured private branch exchange with automatic call
distribution capabilities, primarily targeting enterprises with small to
medium-sized installations. It can be expanded in a modular manner from 32 to
1,024 communications ports and supports up to 100 automatic call distribution
agents. Customers can increase the number of ports and add new features and
applications through the simple installation of add-in cards and software.
Dynamic call routing and control functions are provided by an integrated system
controller running a real-time operating system. PC-based applications and
system features are accessed via a serial interface. The Millennium can be
networked with Cortelco platforms at other sites via a digital network
interface.
 
The following is a diagram of the functional architecture of the Millennium
platform.

                                       24

 
We believe that the Millennium platform is well-suited to address the voice
switching needs of enterprises with small to medium-sized installations,
including schools and school districts, retail sales and service locations,
distribution centers, broadcast and extended health care facilities, government
agencies and small call centers. The key strengths of the Millennium are multi-
site networking, affordable automatic call distribution applications and server
capabilities.
 
Multi-Site Networking. Millennium systems can be connected across multiple
locations, creating a private communications network that operates as if all
sites were on a single system. Therefore, connected locations can share the
Millennium's flexible call routing capabilities and applications. For example,
networked Millennium systems employing our proprietary VoiceClusters technology
can share a single Cortelco Voice Processing System, simplifying system
management and ensuring answering and call routing consistency across
locations. Similarly, networked Millennium systems employing the recently
announced integrated Orbit Wireless Communications System at each location
enables use of the same wireless handset across all locations.
 
Affordable Automatic Call Distribution Applications. A standard feature of the
Millennium is automatic call distribution. The system's dynamic call routing
and report generation capabilities can be enhanced with an optional, real-time
automatic call distribution package that provides call center management data
collection and reporting capabilities for smaller call centers. The Millennium
RealTime Automatic Call Distributor received a "Product of the Year" award from
Call Center Solutions magazine in January 1999.
 
Server Capabilities. The Millennium can be used to perform a variety of server-
like functions. For example, the Millennium can be used as a protocol converter
between E1 trunks, communications links used primarily by European carriers,
and T1 trunks, communications links used primarily in North America. The
Millennium can also be used as a channel bank, a device which merges multiple
voice and data circuits into a single digital communications stream, or act as
the switch in a wireless local loop network. In addition, one Millennium system
at the hub can serve as the single entry point for T1, PRI (Primary Rate ISDN)
and dedicated fiber optic links for the entire enterprise.

The DSP Series
 
The DSP Series is a fully-featured automatic call distributor platform with
integrated private branch exchange capabilities, primarily targeting the call
center market and enterprises with larger installations. It can be expanded in
a modular manner from 8 to 3,500 communications ports and supports up to 1,000
automatic call distribution agents. Its call routing flexibility can support up
to 32,000 routes, each with 64 different steps. Customers can increase the
number of ports and
 

 
 
                                       25

 
add new features and applications through the simple installation of add-in
cards and software. Dynamic call routing and control functions are provided by
redundant Pentium PCs running a real-time Unix-based operating system. PC-based
applications and system features are accessed via an integrated Ethernet LAN
interface. The DSP Series can be networked with Cortelco platforms at other
sites via a digital network interface.
 
The following is a diagram of the functional architecture of the DSP Series
platform.
 
                          [DSP Series Network Diagram]
 
Our DSP Series is primarily designed for call centers across a broad range of
industries including financial services, utilities, catalog sales, service
bureaus and emergency-911 services. The DSP Series is designed to ensure
uninterrupted service by including redundant processing units and power
supplies and using a real-time Unix-based operating system. We believe the DSP
Series is one of the most powerful and economical systems available on a cost-
per-agent basis. The DSP Series won "Best of Show" awards at the 1997 and 1998
CT Expo and "Product of the Year" awards in 1997 and 1998 from Call Center
magazine and in 1999 from Call Center Solutions magazine.
 
The DSP Series provides the platform to handle, manage and improve all aspects
of call center management. Its advanced automatic call distribution
capabilities include real-time dynamic call routing, skill-based routing,
simultaneous queuing among multiple gates and multiple networked systems,
intelligent messages and caller identification number directed routing. The DSP
Series also provides a comprehensive, customizable report and display package
and can support computer telephony integration applications for both inbound
and outbound call center solutions. We currently offer the DSP1000 and DSP2000.
The DSP2000 is an updated version of the DSP1000 which provides an upgrade path
to 3,500 communications ports and support for a greater number of call center
agents. The key strengths of the DSP Series are advanced automatic call
distribution capabilities, host computer telephony integration and PC Phone
Control with ActiveX.
 
Advanced Automatic Call Distribution Capabilities. The advanced automatic call
distribution capabilities of the DSP Series include:
 
    . Home Agent--This feature allows an agent to call into the system from
      a touch-tone phone, sign-on and conduct business as if he or she were
      on-site. The home agent can perform all operations and enter all modes
      as any other on-site agent. Supervisor displays, historical data
      gathering and computer telephony integration applications work
      identically for off-site and on-site agents. Additionally, the home
      agent with a modem-connected PC can retrieve information from
      enterprise databases.
 
    . Automatic Agent Greetings (AgentVoice)--This feature allows an agent
      to pre-record a number of different greetings that can be played based
      upon a caller's identification number. The agent and the caller hear
      the greeting simultaneously, providing a "whisper announce"
      notification for the agent. Pre-recorded responses can be played on
      demand to provide consistent, automated answers to frequently-asked
      questions from callers. AgentVoice is particularly useful for high
      volume call centers and service bureaus in which agents answer calls
      for a variety of different businesses.
 
    . Intelligent Announcement System--This feature enables our customers to
      provide inbound callers with a number of customized delay,
      promotional, informational, holiday, after hours and interactive
      messages. In addition, it can provide the caller with real-time call
      statistics such as estimated wait time, number of calls waiting and
      number of agents available. Our customers can choose from a set of
      pre-recorded voices or create a personalized message from a touch-tone
      phone or a Microsoft Windows-based interface.
 
                                       26

 
    . Agent Call Back--This feature allows a call center agent with
      automatic number identification capability to flag a call, enabling a
      caller who calls back within a given period of time to be routed to
      the agent who originally handled the call.
 
Host Computer Telephony Integration.  The DSP Series offers an applications
link for direct, redundant TCP/IP communications to host computers using
10/100BaseT Ethernet, a standard data networking protocol. This link allows
data and commands to flow between the DSP Series and multiple host computers,
permitting a networked implementation of a variety of enhanced applications
such as screen synchronization, automated outbound dialing, automatic number
identification screening and call routing. The link uses a standard Computer
Supported Telecommunications Application ("CSTA") protocol which functions with
many commercially available computer telephony integration protocols such as
Novell TSAPI, IBM Call Path and Dialogic CT Connect applications. Unlike other
similar competitive offerings, no intermediate computers are required for the
CSTA interface.
 
PC Phone Control with ActiveX.  PC Phone Control is a graphical user interface
for agents to access call center functions such as available/unavailable
status, group pickup, redial and multi-line support. The ActiveX component of
our PC Phone Control provides tools for developers of call center applications
to use a variety of programming languages, including C, C++, Borland Delphi,
Visual Basic and Java, to develop custom applications without the need to
understand complex computer telephony integration protocols. We have won
numerous awards for this product, including a "Best of Show" award at the 1998
CT Expo and a "Product of the Year" award in 1997 from Call Center magazine.

Other Products
 
We also offer a variety of other products for use with both the Millennium and
DSP Series.
 
Voice Processing System.  The Cortelco Voice Processing System manages voice
and fax messaging through integration of the telephone and messaging systems.
This system provides a full range of voice and fax messaging services across
networks running Microsoft NT, Novell NetWare, IBM OS/2 Warp and Artisoft
LANtastic. Our proprietary VoiceClusters technology links multiple Cortelco
Voice Processing System servers into a global messaging system, using existing
wide-area networks to exchange messages between systems. This capability
enables voice and fax message distribution to locations worldwide, improving
message access and reducing transmission costs and delivery time. The system
offers
 
                                       27

 
capabilities to support multiple languages simultaneously and language
preference can be programmed by system, group or individual users. The Cortelco
Voice Processing System is expandable from 4 to 48 ports and supports voicemail
applications for up to 3,000 mailboxes, the Millennium and DSP Series platforms
and many other voice communications platforms.
 
In-building Wireless Communications.  Cortelco's Orbit Wireless Communications
System utilizes micro-cellular technology in the 1.92 to 1.93 gigahertz
frequency band to provide a private digital wireless voice/data communications
network within a building or campus. The system consists of a controller, base
stations and user handsets and can be used with our systems or with any third-
party private branch exchange or key telephone system. These system components
are purchased and licensed from a third-party supplier under an OEM purchase
agreement. We recently announced a Millennium Wireless Services Card of our own
design which we expect to make available during the third quarter of 1999. This
add-in card and software enables full desktop equivalent features on the Orbit
wireless handsets and significantly increases the range of the system and
number of users it can simultaneously support. We plan to provide a similar
add-in card for the DSP Series. The Orbit Wireless Communications System won a
"Best of Show" award at the 1998 CT Expo.
 
Interactive Voice Response.  Cortelco's Illuminations packages are Interactive
Voice Response and Web-enabled self-service information retrieval packages
customized for certain vertical markets. We released the first Illuminations
package, Illuminations for Education, in August 1998. Illuminations for
Education supports such common applications as automated course registration,
automated attendance validation and grade reporting. We are considering the
development of additional packages for the e-commerce, call center, broadcast
and retail markets.
 
PC-Based Attendant Console.  The Navigator attendant console is a hardware and
software based answering and messaging package for use with our Millennium
system. The Navigator enhances an attendant's performance by presenting
appropriate answer phrases, associated company directories, current
availability status of individuals and other useful information with each
inbound call. Calls can be connected to desired parties, on- or off-site, with
a single keystroke or the click of a mouse. Messages can be taken for
unavailable parties or digital pagers can be dialed with preprogrammed callback
numbers displayed. The Navigator provides the attendant with the information
necessary to answer and process efficiently each call presented to the console.
The Navigator is particularly well-suited for multi-tenant applications. A new
version of this product, to be introduced in the third quarter of 1999,
provides the ability to integrate with popular e-mail packages such as
Microsoft Outlook. This product won a "Best of Show" award at the 1997 CT Expo.
 
Third-Party Products and Services in Puerto Rico
 
We resell cellular airtime, cellular telephones and third-party voice
communications systems in Puerto Rico. These third-party products include voice
communications systems from Hitachi and Lucent, sold under distributor
agreements for the Puerto Rico market. Cellular airtime services are resold
under agreements with CellularOne and GTE and cellular telephone equipment is
resold for a variety of equipment suppliers, including Ericsson, Motorola and
Nokia.
 
Customers
 
Cortelco's customers are typically enterprises with small to medium-sized
installations which often have complex communications needs. Many of these
customers are in selected vertical markets in which we have identified needs
that can be especially well served by our systems. These markets currently
include education, retail, government agencies, emergency-911 services and
catalog sales. Some of our customers have multiple installations networked
together and are as large as national retail chains, such as Circuit City and
U-Haul, or multi-location branches of the U.S. government, such as the FAA and
the U.S. Coast Guard.
 
For example, Circuit City, one of the nation's largest retailers of brand-name
consumer electronics equipment, has implemented our products in several hundred
stores throughout the United States. Circuit City's customer service centers
use the Millennium Real-Time Automatic Call Distributor package. The
Millennium's flexible call routing and automatic call distributor capabilities
and its easy installation, programming and setup were important factors for
Circuit City in choosing a Cortelco solution.
 
We have also sold over sixty DSP Series systems to the FAA for use in their
Automated Flight Service Stations. Whenever a general aviation pilot files a
flight plan, checks aviation weather or national airspace information, the call
is answered and routed through a DSP Series system. The DSP Series provides the
FAA with an automatic call distribution platform for applications such as
computer telephony integration, skill-based call routing and remote agents, as
well as full voice routing and control functionality.

Sales and Marketing
 
For the fiscal year ended 1998, approximately 70% of our pro forma revenues
were generated by our direct distribution channels and approximately 30% of our
pro forma revenues were generated by our indirect distribution channels. We use
a direct sales force to market our Millennium systems to national accounts and
the federal government and for all DSP Series system sales. Approximately 130
authorized dealers and value added resellers sell, install and service our
Millennium systems. We directly install, maintain and support our DSP Series
systems. All of our sales in Puerto Rico are made through our direct sales
force. We also offer systems integration services and customized system
development. As of March 31, 1999, we had approximately 71 sales and marketing
personnel. We have increased the number of sales and marketing personnel by
approximately 43% since 1998 and anticipate further increases in the future.
 
Through our office in San Juan, Puerto Rico, our Caribbean and Latin American
Operations unit expects to develop a network of authorized dealers for sales
and service of the Millennium and DSP Series product lines in countries in the
Caribbean, Central America and the northern portion of South America.
Additionally, we expect to open an office in Santiago, Chile, which will
develop and manage a network of authorized dealers for sales and service in
Chile, Ecuador, Peru, Bolivia and Argentina.
 
Our marketing efforts focus on building brand awareness and increasing sales to
customers directly and through our dealer network and value added resellers. We
seek to educate customers in our targeted vertical markets about the benefits
of our flexible product platforms and integrated communications solutions and
the quality of our customer support and services.
 
Research and Development
 
Our research and development efforts focus on enhancing our core product lines
and developing the next generation automatic call distribution and switching
architecture. We routinely conduct market research and solicit input from our
customers and a select set of dealers as an integral part of our product
planning. Current product initiatives include:
 
    . Platform Extensions--Extend and enhance the capabilities of the
      Millennium and DSP Series platforms. Examples include: unified
      messaging support, enhanced integration of our Cortelco Voice
      Processing System, an Orbit Wireless Services Card for the DSP Series
      and 2-wire telephone support for the Millennium.
 
    . Internet-Based Products--Integrate Internet capabilities into
      traditional switched telephony applications. Examples include: voice-
      over-IP and Web-based virtual call center capabilities.
 
                                       29

 
    . Computer Telephony Integration Applications--Extend programming
      interfaces, develop applications and certify third-party computer
      telephony integration products for targeted vertical markets. Examples
      include: TAPI standard computer telephony integration interface,
      Illuminations packages for call centers and retail markets and
      enhanced PC Phone Control with ActiveX.
 
    . Next Generation Core Products--Establish design concepts and
      architecture for new core products that will extend and enhance the
      capabilities of our current Millennium and DSP Series products.
      Consistent with our strategy, new core products will be based on an
      open architecture, will support a broader set of industry standard
      protocols than our current products and will more fully integrate
      emerging voice and data technologies. Examples of the new technologies
      and capabilities we are addressing include: a local area network
      telephony gateway, an IP-based dynamic call routing server for voice
      and data, frame relay and asynchronous transfer mode protocol support,
      and local area network-based IP telephones.
 
As of March 31, 1999, we had 29 employees engaged in research and development.
We have increased the total number of engineers by approximately 21% since
1998. We expect to continue to increase the number of our research and
development employees at a faster rate than other areas and to focus these
additional resources on our new product development initiatives. In particular,
we will expand our capability to design and develop new software features which
are based on industry standard network interfaces, such as asynchronous
transfer mode and frame relay, and industry standard operating systems, such as
Unix and Windows NT.
 
Manufacturing
 
We currently rely on two contract electronic manufacturers to produce the
Millennium, CMC Industries in Corinth, Mississippi and Pensar Corporation in
Appleton, Wisconsin. Both contract manufacturers perform printed circuit board
assembly and soldering, in-circuit and functional testing and packaging. We
believe that CMC and Pensar have sufficient capacity and technical capabilities
to respond to foreseeable increases in customer demand and advances in in-
process technology. After final assembly by either manufacturer, we inspect and
perform quality assurance testing at our facility in Corinth, Mississippi prior
to shipment to our dealers or customers.
 
Due to the custom nature of call center installations, each DSP Series system
is custom-configured at our facility in Kennesaw, Georgia. We use various con-
tract electronic manufacturers to manufacture line cards, trunk cards and other
DSP Series components and subassemblies. We receive, inspect and test compo-
nents and subassemblies at our Kennesaw facility. We then assemble and test
each DSP Series system, configured in accordance with the customer's order, and
ship the product directly to the customer's site.
 
We are dependent on certain key suppliers for a number of our product compo-
nents. For example, we rely on Siemens for our primary digital signal proces-
sors and chip sets and CTP Systems for our Orbit wireless handsets and base
stations. Our contract electronic manufacturers use standard components and
subassemblies manufactured to our specifications. See "Risk Factors--We Depend
on a Single Source of Supply for Some Components."
 
Competition
 
Our principal competitors include Lucent Technologies, Mitel, NEC, Nortel
Networks and Siemens in the voice communications equipment market. In addition
to the foregoing companies, we compete with Aspect Telecommunications and
Rockwell Electronic Commerce in the call center market. We also compete with
vendors in markets for our ancillary products, such as voicemail, wireless
communications and computer telephony integration applications. As voice and
data communications networks converge, data equipment vendors such as Cisco
Systems and 3Com may also compete in our market. In addition, alliances and
mergers between telecommunications and computer companies may strengthen our
competitors' positions or result in new entrants into our market.
 
Many of our current and potential competitors have significantly greater
financial, technical, marketing, customer service and other resources, greater
name recognition and a larger installed customer base than we do. As a result,
our competitors may be able to respond to new or emerging technologies and
changes faster than we can. They may also be able to devote greater resources
to the development, promotion and sale of their products. Actions by our
competitors could result in price reductions, reduced margins and loss of
market share, any of which would have a material adverse effect on our
financial condition. There can be no assurance that we can compete successfully
against our competitors or that competitive pressures would not have a material
adverse effect on our financial condition and results of operations.

Intellectual Property
 
Cortelco relies on patent, trademark, copyright, trade secret protection and
confidentiality and license agreements with its employees, clients, partners
and others to protect its proprietary rights. We currently have 23 patents is-
sued in the United States and additional patents pending. There can be no as-
surance that any patent applications now pending or hereafter filed by Cortelco
will result in patents being issued.
 
The patent position of technology companies involves complex legal and factual
questions and, therefore, their validity and enforceability cannot be predicted
with certainty. There can be no assurance that the steps taken by Cortelco to
protect its proprietary rights will be adequate or that third parties will not
infringe or misappropriate our patents, trade secrets, trademarks and similar
proprietary rights. Furthermore, there can be no assurance that others will not
independently develop similar technologies or duplicate any technology devel-
oped by Cortelco.
 
A failure by Cortelco to protect its intellectual property could have a
material adverse effect on its business, financial condition and results of
operations. In addition, litigation may be necessary in the future to enforce
our intellectual property rights, protect our trade secrets or determine the
validity and scope of the proprietary rights of others. Such litigation could
result in substantial costs and diversion of management and technical
resources, which could have a material adverse effect on our business,
financial condition and results of operations.

      for our DSP Series engineering, manufacturing operations and quality
      assurance departments
 
    . San Juan, Puerto Rico--approximately 15,000 square feet of office
      space for our Caribbean and Latin American Operations unit
 
    . Corinth, Mississippi--approximately 11,000 square feet of warehouse
      space for our Millennium manufacturing operations and quality
      assurance departments
 
    . Englewood, Colorado--approximately 7,000 square feet of office space
      for ACD Business Operations unit sales and marketing and customer
      support departments
 
    . Guelph, Ontario, Canada--approximately 5,000 square feet of office
      space for a software engineering group
 
We expect to relocate our headquarters to a larger facility in Memphis, Tennes-
see in 2000. We believe that these facilities will be adequate to accommodate
our needs for the foreseeable future.
 
Employees
 
As of March 31, 1999, we employed approximately 230 people, including
approximately 71 in sales and marketing, approximately 29 in research and
development, approximately 68 in service, technical support and training,
approximately 24 in manufacturing operations and quality assurance and
approximately 38 in finance and administration. We also employ independent
contractors and other temporary employees. None of our employees is represented
by a labor union, and we consider our employee relations to be good.
Competition for qualified personnel in our industry is intense, particularly
for qualified service technicians and software engineers trained in computer
telephony integration and other technical staff. We believe that our future
success will depend in part on our ability to attract, hire and retain
qualified personnel.
 
Legal Proceedings
 
In the ordinary course of our business, we may from time to time be involved in
litigation with employees, customers and others. In July 1998, we were served
with a complaint by CBC Distribution & Marketing, Inc., ("CDM"), alleging
essentially that a Millennium system purchased by CDM failed to function as
represented. The complaint, which also named our dealer, Technicom
Communications, Inc., and CDM's insurance carrier as defendants, seeks actual
damages of approximately $1.5 million due to disruption of its fantasy football
pool operations plus punitive damages and attorneys'
 
                                       31

 
fees. CDM later amended the complaint to add Sprint International Communica-
tions as a defendant. CDM's insurance carrier also filed a cross-claim against
us. CDM's claim against its insurance carrier and the insurance carrier's
cross-claim against us have since been voluntarily dismissed. We believe that
this litigation is without merit and will not have a material adverse effect on
our business.
 
In addition, in November 1998, WSI, Inc., as debtor in possession in a chapter
XI bankruptcy proceeding, filed an action against Cortelco Puerto Rico,
Cortelco Systems Holding Corporation and David S. Lee, one of our directors, in
bankruptcy court. WSI is a distributor of telecommunications systems in Puerto
Rico. The complaint essentially alleges that the defendants misused
confidential information and otherwise engaged in unfair competition with WSI
by attempting to discredit WSI with Lucent Technologies, Inc. and WSI's
customers in Puerto Rico and to hire WSI employees. The complaint seeks damages
in excess of $15.0 million plus costs and attorneys' fees. We believe that this
litigation is without merit and will not have a material adverse effect on our
business.

Committees of the Board of Directors
 
Our board of directors consists of six members, including our Chief Executive
Officer. In accordance with the terms of our certificate of incorporation, the
terms of office of the board of directors will be divided into three classes:
Class I, whose term will expire at the annual meeting of stockholders to be
held in 2000, Class II, whose term will expire at the annual meeting of
stockholders to be held in 2001, and Class III, whose term will expire at the
annual meeting of stockholders to be held in 2002. The Class I directors are
Stephen R. Bowling and Jenny Hsui Theleen, the Class II directors are Robert P.
Dilworth and David S. Lee, and the Class III directors are W. Frank King and J.
Michael O'Dell. At each annual meeting of stockholders after the initial
classification, the successors to directors whose terms will then expire will
be elected to serve from the time of election and qualification until the third
annual meeting following election. Any additional directorships resulting from
an increase in the number of directors will be distributed among the three
classes so that, as nearly as possible, each class will consist of one-third of
the directors.
 
Our board of directors has established an audit committee and a compensation
committee. The audit committee consists of independent directors Stephen R.
Bowling, Robert P. Dilworth and Jenny Hsui Theleen. The audit committee makes
recommendations to the board regarding the selection of independent auditors,
reviews the results and scope of the audit and other services provided by the
Cortelco's independent auditors, and reviews and evaluates Cortelco's audit and
control functions. The compensation committee consists of Stephen R. Bowling,
W. Frank King, David S. Lee and Jenny Hsui Theleen.

Director Compensation
 
Directors currently do not receive any cash compensation for services provided
as a board member but are reimbursed for out-of-pocket expenses they incur in
connection with attendance at board meetings. Pursuant to the 1997 Equity
Incentive Plan, Robert P. Dilworth and W. Frank King were each granted an
option to purchase 18,000 shares of common stock at an exercise price of $0.70
per share in July 1998 and September 1998, respectively, and an option to
purchase 17,027 shares of common stock at an exercise price of $6.50 per share
in December 1998. Directors are eligible to receive discretionary option grants
pursuant to the 1999 Equity Incentive Plan and employee directors will also be
eligible to participate in the 1999 Employee Stock Purchase Plan. See "--Stock
Incentive Plans."
 
Compensation Committee Interlocks and Insider Participation
 
In April 1998, our board of directors established a compensation committee. The
compensation committee is responsible for approving all compensation
arrangements for our officers and for administering our employee stock option
and stock purchase plans. In the last fiscal year, the compensation committee
was composed of Stephen R. Bowling, David S. Lee and Jenny Hsui Theleen. W.
Frank King joined the compensation committee in February 1999. Other than
Stephen R. Bowling, who served as Cortelco's President from 1994 to October
1997 and as Cortelco's Chief Executive Officer from 1994 to April 1998, none of
the members of the compensation committee are, or have ever been, officers or
employees of Cortelco. Prior to the formation of the compensation committee,
all decisions regarding compensation arrangements for our officers were made by
the board of directors. See "Certain Transactions."
 
Executive Compensation
 
The following table sets forth certain information concerning the compensation
earned for the fiscal year ended July 31, 1998 for (a) Cortelco's Chief
Executive Officer and (b) each other executive officer of Cortelco whose total
salary and bonus exceeded $100,000 for services rendered to Cortelco and its
subsidiaries during the fiscal year 1998 (the "Named Executive Officers"). For
information regarding terms of the stock options, see "--Stock Incentive
Plans."

- -------------------
(1) The annual compensation of each of Robert R. Cash, David M. Fredrick and
    Sergio R. Moren exceeds $100,000. However, because each of the above
    individuals were hired during fiscal year 1998, their total compensation
    earned as of the end of fiscal year 1998 did not exceed $100,000 and
    therefore they are not included as Named Executive Officers.
(2) J. Michael O'Dell joined Cortelco as President and Chief Operating Officer
    in October 1997 and became the Chief Executive Officer of Cortelco in April
    1998.
(3) Stephen R. Bowling previously served as President of Cortelco until October
    1997 and Chief Executive Officer until April 1998.

The following table sets forth each grant of stock options made during the
fiscal year ended July 31, 1998 to each of the Named Executive Officers:
 
- -------------------
(1) Options generally vest at a rate of 12.5% on the date six months after the
    vesting commencement date and the remaining options vest in equal
    installments on a monthly basis over a three and one-half year period
    thereafter. These options have a term of 10 years.
(2) Based on an aggregate of 139,311 shares subject to options granted to
    employees of Cortelco under the 1997 Equity Incentive Plan in fiscal 1998,
    including the Named Executive Officers.
(3) The potential realizable value is calculated based on the term of the
    option at the time of grant, which is 10 years. Stock price appreciation of
    5% and 10% is assumed pursuant to rules promulgated by the SEC and does not
    represent our prediction of our stock price performance. The potential
    realizable value at 5% and 10% appreciation is calculated by assuming that
    the exercise price on the date of grant appreciates at the indicated rate
    for the entire term of the option and that the option is exercised at the
    exercise price and sold on the last day of its term at the appreciated
    price.

    options have a term of 10 years.
(2) There was no public trading market for the common stock as of April 15,
    1999. Accordingly, these values have been calculated based on the initial
    offering price as set forth on the cover page of this prospectus.
 
Stock Incentive Plans
 
1999 Equity Incentive Plan
 
In April 1999, our board of directors adopted, and the stockholders approved,
the 1999 Equity Incentive Plan (the "1999 Incentive Plan"). There is currently
an aggregate of 2,000,000 shares of common stock authorized for issuance under
the 1999 Incentive Plan. The 1999 Incentive Plan provides for the grant of
incentive stock options, as defined under the Internal Revenue Code of 1986, as
amended (the "Code"), to employees and nonstatutory stock options, restricted
stock purchase awards, stock bonuses and stock appreciation rights to
employees, directors and consultants of Cortelco and its affiliates. The 1999
Incentive Plan is administered by a committee appointed by the board of
directors which determines recipients and types of awards to be granted,
including the exercise price, the number of shares subject to the award, the
vesting rate and the exercisability of awards.
 
The terms of options granted under the 1999 Incentive Plan may not exceed 10
years. The exercise price is determined by the board of directors, provided
that, the exercise price for an incentive stock option cannot be less than 100%
of the fair market value of the common stock on the date of the option grant,
and the exercise price for a nonstatutory stock option
 
                                       36

 
cannot be less than 85% of the fair market value of the common stock on the
date of the option grant. Generally, the optionee may not transfer a stock
option other than by will or the laws of descent or distribution unless the
optionee holds a nonstatutory stock option that provides for transfer in the
stock option agreement. However, an optionee may designate a beneficiary who
may exercise the option following the optionee's death. An optionee whose
service relationship with Cortelco or any affiliate ceases for any reason may
exercise vested options for the term provided in the option agreement.
 
No incentive stock option may be granted to any person who, at the time of the
grant, owns, or is deemed to own, stock possessing more than 10% of the total
combined voting power of Cortelco or any affiliate of Cortelco, unless the
option exercise price is at least 110% of the fair market value of the stock
subject to the option on the date of grant and the term of the option does not
exceed five years from the date of grant. In addition, the aggregate fair
market value, determined at the time of grant, of the shares of common stock
with respect to which incentive stock options are exercisable for the first
time by an optionee during any calendar year, under all Cortelco stock plans
and its affiliates, may not exceed $100,000.
 
When Cortelco becomes subject to Section 162(m) of the Code, which denies a
deduction to publicly held corporations for certain compensation paid to
specified employees in a taxable year to the extent that the compensation
exceeds $1,000,000, no person may be granted options under the 1999 Incentive
Plan covering more than 500,000 shares of common stock in any calendar year.
 
Shares subject to stock awards that have expired or otherwise terminated
without having been exercised in full again become available for the grant of
awards under the 1999 Incentive Plan. Restricted stock purchase awards granted
under the 1999 Incentive Plan may be granted pursuant to a repurchase option in
favor of Cortelco in accordance with a vesting schedule and at a price
determined by the board of directors. Stock bonuses may be awarded in
consideration of past services without a purchase payment. Unless otherwise
specified, rights under a stock bonus or restricted stock bonus agreement
generally may not be transferred other than by will or the laws of descent and
distribution during such period as the stock awarded pursuant to such an
agreement remains subject to the agreement.
 
If there is any sale of substantially all of Cortelco's assets, any merger,
reverse merger or any consolidation in which Cortelco is not the surviving
corporation, or any acquisition by certain persons, entities or groups of 50%
or more of Cortelco's stock, all outstanding awards under the 1999 Incentive
Plan either will be assumed or substituted by any surviving entity. If the
surviving entity determines not to assume or substitute such awards, the
vesting provisions of such stock awards will be accelerated and the awards
terminated if not exercised prior to the such transaction.
 
As of April 15, 1999, no stock bonuses or restricted stock awards had been
granted, options to purchase 270,000 shares of common stock were outstanding,
no options have been exercised and 1,730,000 shares remained available for
future grants pursuant to the 1999 Incentive Plan. The 1999 Incentive Plan will
terminate in April 2009.
 
1997 Equity Incentive Plan
 
In April 1998, our board of directors and stockholders approved the 1997 Stock
Incentive Plan (the "1997 Incentive Plan"), which provides for the grant of
incentive stock options, nonqualified stock options and restricted stock awards
to employees and consultants. A maximum of 450,000 shares of common stock have
been reserved for issuance under the 1997 Incentive Plan. In addition, the
aggregate fair market value, determined at the time of grant, of the shares of
common stock with respect to which incentive stock options are exercisable for
the first time by an optionee during any calendar year, under all stock plans
of Cortelco and its affiliates, may not exceed $100,000.
 
The 1997 Incentive Plan is administered by the board of directors, which has
the authority to determine which eligible individuals are to receive options or
restricted stock awards, the terms of such options or awards, the status of
such options as incentive or nonqualified stock options under the federal
income tax laws, including the number of shares, exercise or purchase prices
and exercisability, vesting schedule and the time, manner and form of payment
upon exercise of an option. The exercise price of options granted under the
1997 Incentive Plan is determined by the compensation committee. The options
expire after a specified period that may not exceed ten years or in the case of
a stockholder holding greater than 10% of the voting power, five years. As of
April 15, 1999, options to purchase 333,826 shares were outstanding, no options
had been exercised, and 116,174 shares remained available for future grants
pursuant to the 1997 Incentive Plan. The 1997 Incentive Plan will terminate in
April 2008. Our board of directors has determined that no further options will
be granted under the 1997 Incentive Plan after the completion of this offering.
 
1997 Equity Incentive Plan of BCS Technologies, Inc.
 
In April 1999, in connection with the acquisition of BCS, we assumed the 1997
Stock Incentive Plan of BCS, (the "BCS 1997 Incentive Plan"), which provides
for the grant of incentive stock options, nonqualified stock options and
 
                                       37

 
restricted stock awards to employees and consultants. A maximum of 96,495
shares of our common stock have been reserved for issuance under the BCS 1997
Incentive Plan. As of April 15, 1999, options to purchase 94,279 shares were
outstanding, no options had been exercised, and 2,216 shares remained available
for future grants pursuant to the BCS 1997 Incentive Plan. The BCS 1997
Incentive Plan will terminate in January 2007. Our board of directors has
determined that no further options will be granted under the BCS 1997 Incentive
Plan after the completion of this offering.
 
1999 Employee Stock Purchase Plan
 
In April 1999, our board of directors and stockholders approved the 1999
Employee Stock Purchase Plan, which enables eligible employees to acquire
shares of common stock through payroll deductions. The 1999 Employee Stock
Purchase Plan is intended to qualify as an "employee stock purchase plan" under
Section 423 of the Code. The initial offering period will start on the date of
this prospectus and end on August 31, 2000, with purchase dates on February 29,
2000 and August 31, 2000, unless otherwise determined by our board of
directors. Each offering under the 1999 Employee Stock Purchase Plan after the
initial offering will run for one year, unless otherwise determined by the
board of directors prior to the beginning of such offering. During each
offering period, an eligible employee may select a rate of payroll deduction of
up to 15% of compensation. The purchase price for the common stock purchased
under the 1999 Employee Stock Purchase Plan is 85% of the lesser of the fair
market value of the shares on the first day or the purchase date. An aggregate
of 250,000 shares of common stock have been reserved for issuance under the
1999 Employee Stock Purchase Plan.
 
Employment Agreement
 
With the exception of David M. Fredrick, Vice President/General Manager of ACD
Business Operations, none of our executive officers has an employment
agreement, and each of such executive officers serves at the discretion of our
board of directors. On April 12, 1999, Cortelco entered into an employment
agreement with Mr. Fredrick. Pursuant to the terms of such agreement, Mr.
Fredrick is to receive annual salary of $165,000 in 1999 and an annual salary
of $175,000 in 2000. Mr. Fredrick will receive an option to purchase 70,000
shares of common stock, 60,000 shares of which vest on January 2, 2001 and
10,000 shares of which vest on January 2, 2002.
 
401(k) Plan
 
Effective July 15, 1990, as amended on October 1, 1995, our board of directors
adopted an employee savings and retirement plan (the "401(k) Plan") covering
certain of our employees. Pursuant to the 401(k) Plan, eligible employees may
elect to reduce their current compensation by up to the lesser of 16% of such
compensation or the statutorily prescribed annual limit ($10,000 in 1998) and
have the amount of such reduction contributed to the 401(k) Plan. Cortelco may
make contributions equal to 50% of the first 6% of the total of an employee's
elective contribution and/or their after-tax employee contribution up to a
maximum of $2,000 to the 401(k) Plan on behalf of eligible employees.
Additionally, we may make an additional non-matching contribution on a
discretionary basis on behalf of all eligible employees. The 401(k) Plan is
intended to qualify under Section 401 of the Code so that contributions by
employees or by Cortelco to the 401(k) Plan, and income earned on the 401(k)
Plan contributions, and so that contributions by Cortelco, if any, will be
deductible by us when made. The trustee under the 401(k) Plan, at the direction
of each participant, invests the 401(k) Plan employee salary deferrals in
selected investment options. We made contributions to the 401(k) Plan in fiscal
1998 and in the first quarter of fiscal 1999. We presently expect to make
monthly contributions to the 401(k) Plan during fiscal 1999.
 
Limitation of Liability and Indemnification Matters
 
Our bylaws provide that we will indemnify our directors and executive officers
and may indemnify our other officers, employees and agents to the fullest
extent permitted by Delaware law. We are also empowered under our bylaws to
enter into indemnification contracts with our directors and executive officers
and to purchase insurance on behalf of any person we are required, or
permitted, to indemnify. Pursuant to this provision, we expect to enter into
indemnity agreements with each of our directors and executive officers.
 
In addition, our certificate of incorporation provides that, to the fullest
extent permitted by Delaware law, our directors will not be liable for monetary
damages for breach of the directors' fiduciary duty of care to us and our
stockholders. This provision in the certificate of incorporation does not
eliminate the duty of care, and in appropriate circumstances equitable remedies
such as an injunction or other forms of non-monetary relief would remain
available under Delaware law. Each director will continue to be subject to
liability for breach of the director's duty of loyalty to us, acts or omissions
not in good faith or involving intentional misconduct, knowing violations of
law, for any transaction from which the director
 
                                       38

 
derived an improper personal benefit, improper transactions between the
director and us and improper distributions to stockholders and loans to
directors and officers. This provision also does not affect a director's
responsibilities under any other laws, such as the federal securities laws or
state or federal environmental laws.
 
We expect to enter into agreements with our directors and officers that require
us to indemnify such persons against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred (including expenses of a
derivative action) in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or officer of Cortelco or any of its
affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in, or not opposed to, the best
interests of Cortelco and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The
indemnification agreements also set forth certain procedures that will apply in
the event of a claim for indemnification thereunder.
 
                                       39

 
                       Principal and Selling Stockholders
 
The following table sets forth certain information with respect to the
beneficial ownership of Cortelco's outstanding common stock as of April 15,
1999 and as adjusted to reflect the sale of the common stock being offered
hereby by (1) each person (or group of affiliated persons) who is known by
Cortelco to own beneficially more than 5% of the common stock, (2) each of the
Named Executive Officers, (3) each of the directors, (4) all directors and
executive officers of Cortelco as a group and (5) each of Cortelco's current
stockholders who is expected to sell shares in the offering. Unless otherwise
specified, the address of the stockholder is the address of Cortelco set forth
in this prospectus.
 
Beneficial ownership is determined in accordance with the rules of the SEC and
generally means sole or shared power to vote or direct the voting or to dispose
or direct the disposition of any common stock. Except as indicated by footnote,
and subject to community property laws where applicable, the persons named in
the table below have sole voting and investment power with respect to all
shares of common stock shown as beneficially owned by them. The percentage of
beneficial ownership is based on 9,074,827 shares of common stock outstanding
as of April 15, 1999 and     shares of common stock outstanding after
completion of this offering assuming no exercise of the underwriters' over-
allotment option. If the underwriters' over-allotment option is exercised in
full, Cortelco and certain stockholders will sell up to     shares of common
stock, and     shares of common stock will be outstanding after the completion
of this offering.

                              Certain Transactions
 
Prior to April 1999, Cortelco was a subsidiary of Cortelco Systems Holding
Corporation and from time to time engaged in intercompany transactions with its
parent and affiliates. See note 15 to our consolidated financial statements.
The Cortelco common stock held by our parent company was pledged to secure a
debt obligation in the amount of $3,600,000 as of December 31, 1998. In order
to release this stock from the pledge so that Cortelco Systems Holding
Corporation could distribute it to the holders of its capital stock and
facilitate the acquisition of BCS, an agreement was entered into with the
lender on February 25, 1999 to repay the remaining principal of this obligation
in several installments, the last of which is due in May 1999. We expect to
loan $2,600,000 at an interest rate equal to the prime rate plus 1.5% to
Cortelco Systems Holding Corporation to be used for these payments, of which
$1,300,000 has been advanced as of April 15, 1999. We have also declared
dividends in the amount of $2,658,000, payable upon completion of this
offering, which will be applied to repaying the principal of the loan.
Following release of the pledge, Cortelco Systems Holding Corporation
distributed a total of 2,856,944 shares of our common stock to its stockholders
in April 1999 (the "Spin-Off"). In connection with the Spin-Off, Cortelco
Systems Holding Corporation distributed: 1,137,364 shares of common stock to
David S. Lee, chairman of Cortelco; 612,530 shares to CMC; and 4,667 shares to
Stephen R. Bowling, a director of Cortelco. David S. Lee is also Chairman and a
principal stockholder of Cortelco Systems Holding Corporation. Stephen
R. Bowling is also President, Chief Executive Officer and a director of
Cortelco Systems Holding Corporation. CMC Industries is affiliated with
Cortelco through common stock ownership.
 
Pursuant to a Convertible Note Purchase Agreement dated as of July 31, 1997, we
sold a convertible promissory note in the aggregate principal amount of
$3,000,000 to ChinaVest, a principal stockholder. The note matures on July 31,
2002 and accrues interest at the rate of 8.0%, payable on the maturity date or
sixty days following the date of conversion. On April 12, 1999, in accordance
with the terms of the note, ChinaVest converted $686,000 of outstanding
principal into 1,463,206 shares of Series A Convertible Preferred Stock. The
Series A Convertible Preferred Stock automatically converts into 1,434,894
shares of our common stock upon completion of this offering. The remaining
principal amount of $2,314,000, plus accrued interest, outstanding under the
note will be paid from the proceeds of this offering. See "Use of Proceeds."
Jenny Hsui Theleen, a director of Cortelco, is a managing director of
ChinaVest.
 
In July 1997, we loaned Cortelco Systems Holding Corporation the principal
amount of $3,184,000. The note accrues interest at the rate of 8.0% per annum.
In April 1999, we repurchased 250,000 shares of our common stock from Cortelco
Systems Holding Corporation in exchange for the cancellation of $2,500,000 of
the principal amount of the note. The remaining principal amount of $684,000,
plus accrued interest, is due in November 2000.
 
In October 1997, we loaned J. Michael O'Dell, our Chief Executive Officer and a
director, the principal amount of $132,000 in connection with relocation
expenses. J. Michael O'Dell repaid $61,000 of principal on the note in October
1998. The balance is due in October 1999.
 
In April 1998, we sold a Millennium system to a public television station for
$210,000. The funding for the purchase was based on a directed donation from
David S. Lee through the Asia Cultural Teachings Corporation, a charitable
foundation. David S. Lee is the honorary president of Asia Cultural Teachings
Corporation.
 
In April 1998, David S. Lee loaned Cortelco the principal amount of $250,000,
payable on demand. The note was non-interest bearing and was repaid in full in
October 1998. In February 1999, we distributed a note receivable from David S.
Lee in the amount of $250,000, which had been recorded as an offset to
stockholders equity, to Cortelco Systems Holding Corporation as a dividend.
 
In April 1999, we declared and paid a stock dividend of 195,684 shares of
common stock.
 
In connection with the BCS acquisition, we issued 1,036,014 shares of our
common stock to David S. Lee, 636,517 shares to David M. Fredrick, 616,444
shares to Frank Naso, 453,562 shares to ChinaVest and 3,321 shares to Stephen
R. Bowling in exchange for their stockholdings in BCS. See "Company
Background." We also entered into an employment agreement with David M.
Fredrick and Frank Naso. See "Management--Employment Agreements."
 
Since 1993, CMC Industries, Inc., a principal stockholder, has provided certain
manufacturing services on a non-exclusive basis. The current agreement with
CMC, dated as of August 1, 1998, expires on July 31, 1999, and is renewable
annually by Cortelco. David S. Lee is Chairman and a principal stockholder of
CMC.
 
We purchase single line phones from, and sell Millennium related products to,
Cortelco International, Inc., a wholly- owned subsidiary of Cortelco Systems
Holding Corporation. David S. Lee and Stephen R. Bowling are directors of
 
                                       42

 
Cortelco International, Inc. In fiscal 1998, our purchases from Cortelco
International, Inc. totaled $85,000 and our sales totaled $188,000.
 
Cortelco believes that all of the transactions set forth above were made on
terms no less favorable to Cortelco than could have been otherwise obtained
from unaffiliated third parties. As a matter of policy, all future transactions
between Cortelco and any of its officers, directors or principal stockholders
will be approved by a majority of the board of directors, including a majority
of the independent and disinterested members of the board.

                          Description of Capital Stock
 
The following description of our capital stock and provisions of our
certificate of incorporation and bylaws is a summary and is qualified in its
entirety by the provisions of our certificate of incorporation and bylaws,
which have been filed as exhibits to our registration statement, of which this
prospectus is a part.
 
Upon the closing of this offering, our authorized capital stock will consist of
50,000,000 shares of common stock, $.001 par value per share, and 10,000,000
shares of preferred stock, $.001 par value per share. As of April 15, 1999,
there were 9,074,827 shares of common stock outstanding held of record by
approximately 120 stockholders.
 
Common Stock
 
The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. The holders of
common stock are not entitled to cumulative voting rights with respect to the
election of directors, and as a consequence, minority stockholders will not be
able to elect directors on the basis of their votes alone. Subject to
preferences that may be applicable to any then outstanding shares of preferred
stock, holders of common stock are entitled to receive ratably such dividends
as may be declared by the board of directors out of funds legally available for
dividends. In the event of our liquidation, dissolution or winding up, holders
of the common stock are entitled to share ratably in all assets remaining after
payment of liabilities and the liquidation preference of the preferred stock,
if any, then outstanding. Holders of common stock have no preemptive rights and
no right to convert their common stock into any other securities. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are, and all shares of common stock to be
outstanding upon completion of this offering will be, fully paid and non-
assessable.
 
Preferred Stock
 
The board of directors has the authority, without further action by the
stockholders, to issue any undesignated shares of preferred stock in one or
more series and to fix the rights, preferences, privileges and restrictions of
any shares of preferred stock, including dividend rights, conversion rights,
voting rights, terms of redemption, liquidation preferences, sinking fund terms
and the number of shares constituting any series or the designation of such
series, without any further vote or action by stockholders. The issuance of
preferred stock could adversely affect the voting power of holders of common
stock and the likelihood that such holders will receive dividend payments and
payments upon liquidation and could have the effect of delaying, deferring or
preventing a change in control of Cortelco. We have no present plan to issue
any shares of preferred stock.
 
Registration Rights
 
After this offering, the holders of approximately      shares of common stock
will be entitled to rights to require the registration of such shares under the
Securities Act. If we propose to register any of our securities under the
Securities Act, either for our own account or for the account of other security
holders exercising registration rights, such holders are entitled to notice of
such registration and are entitled, subject to certain limitations, to include
their shares to be registered. The holders may also require us to file a
registration statement under the Securities Act with respect to their shares,
and we are required to use our best efforts to effect up to two such
registrations. Furthermore, the holders may require us to register their shares
on Form S-3 when we become eligible to use such form. Generally, we are
required to bear all registration and selling expenses incurred in connection
with any registrations except for underwriting discounts and commissions. These
rights are subject to conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares included in such
registration.
 
Delaware Anti-Takeover Law and Certain Charter Provisions
 
We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, an anti-takeover law. In general, the statute prohibits a
publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless
the business combination is approved in a prescribed manner. For purposes of
Section 203, a "business combination" includes a merger, asset sale or other
transaction resulting in a financial benefit to the interested stockholder, and
an "interested stockholder" is a person who, together with affiliates and
associates, owns or within three years prior did own, 15% or more of the
corporation's voting stock.

Our certificate of incorporation, effective upon the closing of this offering,
also requires that (1) the terms of the board of directors will be staggered
into three classes, (2) any action required or permitted to be taken by
stockholders of Cortelco must be effected at a duly called annual or special
meeting of the stockholders and may not be effected by written consent, (3) the
stockholders may amend our bylaws or adopt new bylaws only by the affirmative
vote of 66 2/3% of the outstanding voting securities and (4) special meetings
of our stockholders may be called only by the board of directors, the Chairman
of the Board or the Chief Executive Officer. These provisions may have the
effect of delaying, deferring or preventing a change in control of Cortelco.

                        Shares Eligible for Future Sale
 
Prior to this offering, there has been no market for our common stock. Future
sales of substantial amounts of common stock in the public market could
adversely affect market prices prevailing from time to time. Furthermore, since
only a limited number of shares will be available for sale shortly after this
offering because of contractual and legal restrictions on resale described
below, sales of substantial amounts of common stock in the public market after
the restrictions lapse could adversely affect the prevailing market price and
our ability to raise equity capital in the future.
 
Upon completion of the offering, we will have     shares of common stock
outstanding, assuming no exercise of the underwriters' over-allotment option
and no exercise of outstanding options and warrants and based upon the number
of shares outstanding as of     , 1999. Of these shares, the shares sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless such shares are purchased by our
"affiliates," as that term is defined in Rule 144 under the Securities Act. The
remaining    shares held by existing stockholders, and any shares purchase by
affiliates in this offering, will be "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Our affiliates hold      of the
restricted shares. Restricted shares may be sold in the public market only if
registered or if they qualify for an exemption from registration under Rules
144, 144(k) or 701 under the Securities Act, which are summarized below.
 
Upon completion of this offering, the holders of     shares of common stock, or
their transferees, will be entitled to rights to require the registration of
such shares under the Securities Act. Registration of such shares under the
Securities Act would result in such shares becoming freely tradable without
restriction under the Securities Act, except for shares purchased by our
affiliates, immediately upon the effectiveness of such registration. See
"Description of Capital Stock--Registration Rights."
 
We, our officers, directors and        stockholders will agree under written
lock-up agreements not to, without the prior written consent of J.P. Morgan
Securities Inc., sell any shares of common stock for 180 days after the date of
this prospectus. See "Underwriting."
 
In general, under Rule 144 as currently in effect, beginning 90 days after the
date of this prospectus, stockholders who have beneficially owned restricted
shares for at least one year will be entitled to sell in any three-month period
a number of shares that does not exceed the greater of one percent of the then
outstanding shares of our common stock or the average weekly trading volume of
our common stock in the Nasdaq National Market during the four calendar weeks
immediately preceding the date on which notice of the sale is filed with the
SEC. Sales pursuant to Rule 144 are subject to certain requirements relating to
manner of sale, notice and availability of current public information about
Cortelco. A person, or person whose shares may be aggregated, who is not deemed
to have been one of our affiliates at any time during the 90 days immediately
preceding the sale and who has beneficially owned restricted shares for at
least two years is entitled to sell such shares pursuant to Rule 144(k) without
regard to the limitations described above.
 
Any of our employees, directors or consultants who purchased, or was awarded
shares or options to purchase shares pursuant to a written compensatory plan or
contract is entitled to rely on the resale provisions of Rule 701 under the
Securities Act, which permits stockholders to sell their Rule 701 shares
without having to comply with Rule 144's holding period restrictions, in each
case commencing 90 days after the date of this prospectus. In addition, holders
who are not affiliates may sell Rule 701 shares without complying with the
public information, volume and notice provisions of Rule 144.
 
We intend to file a registration statement under the Securities Act covering
shares of common stock reserved for issuance under our Stock Incentive Plans
and the Purchase Plan. Based on the number of options outstanding and options
and shares reserved for issuance at     , 1999, such registration statement
will cover approximately      shares. Such registration statement is expected
to be filed and to become effective as soon as practicable after the date of
this prospectus. Shares registered under such registration statement will,
subject to Rule 144 volume limitations applicable to affiliates, be available
for sale in the open market, unless such shares are subject to vesting
restrictions with Cortelco or the lock-up agreements described above. See
"Management."

The underwriters are offering the common stock subject to their acceptance of
the common stock and subject to prior sale. The underwriting agreement provides
that the obligations of the underwriters to purchase shares of common stock are
subject to the approval of certain legal matters by counsel and to certain
other conditions. If any of the shares of common stock are purchased by the
underwriters pursuant to the underwriting agreement, all of the shares, other
than the shares of common stock covered by the over-allotment option described
below, must be purchased.
 
The underwriters propose to offer the shares of common stock directly to the
public at the public offering price set forth on the cover page of this
prospectus and to dealers at such price less a concession not in excess of $
per share. The underwriters may allow, and such dealers may reallow, a
concession not in excess of $    per share to other dealers. After the initial
public offering of the common stock, the offering price and other selling terms
may be changed from time to time by the underwriters.
 
We and certain selling stockholders have granted to the underwriters an option
to purchase up to     additional shares of common stock on the same terms and
conditions solely to cover over-allotments. The option may be exercised during
the 30-day period after the date of this prospectus. If the underwriters'
option is exercised in full, the total price to public would be $   , the total
underwriting discounts and commissions would be $   , and total proceeds to us
would be $   , before deducting $    in expenses.
 
We and the selling stockholders have agreed to indemnify the underwriters
against specified liabilities, including liabilities under the Securities Act,
and to contribute to payments that the underwriters may be required to make in
connection with such liabilities.
 
We, our officers, directors and         stockholders will agree not to, without
the prior written consent of J.P. Morgan Securities Inc., (1) offer, pledge,
announce the intention to sell, sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase or otherwise transfer or dispose of,
directly or indirectly, any shares of common stock or any securities of
Cortelco which are substantially similar to the common stock, including but not
limited to any securities that are convertible into or exercisable or
exchangeable for, or that represent the right to receive common stock or any
such substantially similar securities or (2) enter into any swap, option,
future, forward or other agreement that transfers, in whole or in part, any of
the economic consequences of ownership of common stock or any securities
substantially similar to the common stock. We may, however, issue shares of
common stock upon the exercise of stock options that are currently outstanding,
and may grant additional options under its stock option plans, provided that,
without the prior written consent of J.P. Morgan Securities Inc., such
additional options shall not be exercisable during such period.
 
In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a
syndicate short position. In addition, the underwriters may bid for, and
purchase, shares of common stock in the open market to cover syndicate short
positions or to stabilize the price of the common stock. Finally, the
underwriting syndicate may reclaim selling concession allowed for distributing
the common stock in the offering, if the syndicate repurchases previously
distributed common stock
 
                                       47

 
in syndicate covering transactions, in stabilization transactions or otherwise.
Any of these activities may stabilize or maintain the market price of the
common stock above independent market levels. The underwriters are not required
to engage in these activities, and may end any of these activities at any time.
 
Prior to this offering, there has been no public market for our common stock.
The initial public offering price for the shares of common stock offered in
this offering will be determined by negotiation among Cortelco, the selling
stockholders and the underwriters. Among the factors to be considered in
determining the initial public offering price are our revenue and earnings,
market valuations of other companies engaged in activities similar to ours,
estimates of our business potential and prospects, the present state of our
business operations, our management, the general condition of the securities
markets at the time of the offering and other factors deemed relevant. The
estimated initial public offering price range set forth on the cover of this
preliminary prospectus is subject to change as a result of market conditions
and other factors. There can be no assurance that an active trading market will
develop for our common stock or that our common stock will trade in the public
market at or above the initial public offering price.

                          Independent Auditors' Report
 
To the Board of Directors and Stockholders of Cortelco Systems, Inc.
 
We have audited the accompanying consolidated balance sheets of Cortelco
Systems, Inc. and subsidiaries (the "Company"), a 97% owned subsidiary of
Cortelco Systems Holding Corporation, as of July 31, 1997 and 1998 and the
related consolidated statements of operations, cash flows, and stockholders'
equity (deficit) for each of the three years in the period ended July 31, 1998.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. We did not audit the statements of operations and cash flows of
Cortelco Puerto Rico, Inc. (a consolidated subsidiary) for the year ended July
31, 1996, which statements reflect total revenues constituting 39.7% of the
related consolidated total for that year. Those statements were audited by
other auditors whose report has been furnished to us and our opinion, insofar
as it relates to the amounts included for Cortelco Puerto Rico, Inc. for the
year ended July 31 1996, is based solely on the report of such other auditors.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
In our opinion, based on our audits and the report of other auditors, such
consolidated financial statements present fairly, in all material respects, the
financial position of Cortelco Systems, Inc. and its subsidiaries at July 31,
1997 and 1998 and the results of their operations and their cash flows for each
of the three years in the period ended July 31, 1998 in conformity with
generally accepted accounting principles.

1. Description of Business and Organization
 
Description of Business--Cortelco Systems, Inc. (the "Company" or "CSI")
designs, develops and markets integrated enterprise communications systems for
routing and controlling the voice, video and data communications of businesses
and other organizations. In addition to selling Millennium systems and related
systems products, Cortelco also resells cellular airtime, cellular telephones
and third-party voice communications systems in Puerto Rico.
 
Organization--Effective July 31, 1993, the telecommunications business of CMC
Industries, Inc. ("CMC") was spun-off to Cortelco Systems Holding Corporation
("CSHC", the parent company). From August 1, 1993 to July 31, 1995, CSHC
combined the operations of the Company (the "Systems" and "Automatic Call
Distributor" product lines) with the operations related to another product
line, single line telephones, and accounted for these product lines as a single
business unit.
 
Effective August 1, 1995, CSHC contributed the assets of the "Systems" and
"Automatic Call Distributor" product lines to the Company. The assets were
recorded at historical book value.
 
2. Basis of Presentation
 
Basis of Presentation--The Company was a 97% owned subsidiary of CSHC through
April 1999. The consolidated financial statements of CSI include the accounts
of its wholly-owned subsidiaries, Cortelco Puerto Rico, Inc. for all periods
presented and Cortelco, Inc. (the "Automatic Call Distributor" product line)
through March 31, 1997, at which time Cortelco, Inc. was spun-off to CSHC (see
Note 4). The consolidated financial statements also include the accounts of its
55% owned joint venture in mainland China since the date of acquisition (see
Note 9). Minority interest is recognized for the remaining 45% interest in the
financial position and operations of the joint venture. All significant
intercompany balances have been eliminated.
 
The Company is also affiliated with the following entities through common
stockholder ownership:
 
  Cortelco International, Inc. ("CII", subsidiary of CSHC)
  Cortelco Puerto Rico, Inc. ("CPR", subsidiary of CSHC)
  Cortelco Canada ("CC", subsidiary of CSHC)
  BCS Technologies, Inc.
  CMC Industries, Inc.
 
The Company also has two inactive subsidiaries, Cortelco Holding Corp. and CTC
Holding Corp.
 
In April 1999 a series of transactions occurred whereby CSHC distributed the
common stock of the Company to the CSHC stockholders and CPR formed a new
wholly-owned subsidiary in the Commonwealth of Puerto Rico, Cortelco Systems
Puerto Rico, Inc. ("CSPR"), in contemplation of a merger between the Company
and the newly formed subsidiary. Previous to the merger, CPR contributed
substantially all of the operations and certain assets and liabilities to the
newly formed CSPR. Cortelco Puerto Rico, Inc. retained certain real estate
assets and the related mortgage note payable. On April 8, 1999, CPR transferred
all issued and outstanding stock of CSPR to CSHC, the Company issued 553,880
shares of common stock to CSHC in exchange for an 100% interest in CSPR and
CSPR assumed the CPR Credit Facility described in Note 11. As the business
combination was between entities under common control, the merger has been
accounted for in a manner similar to a pooling of interests and accordingly,
all periods presented in the accompanying financial statements reflect the
results of operations on an "as if pooled" basis. The common stock issued to
effect the business combination has been reflected as outstanding for all
periods presented.
 
3. Summary of Significant Accounting Policies
 
Cash and Cash Equivalents--All highly liquid investments with a maturity of
three months or less are considered to be cash equivalents.
 
 
                                      F-7

 
                    Cortelco Systems, Inc. and Subsidiaries
 
            Notes to Consolidated Financial Statements--(Continued)
                    Years Ended July 31, 1996, 1997 and 1998
 
The Company provides a centralized cash management function whereby all cash
receipts on customer accounts are processed through a lockbox arrangement and
swept daily to paydown the line of credit agreement discussed in Note 11. All
cash disbursements are handled through daily draws on the line of credit to
cover the Company's outstanding checks.
 
Inventories--Inventories are valued at the lower of cost or market. Cost is
determined by the last-in, first-out ("LIFO") method for approximately 81% and
72% of the inventories at July 31, 1997 and 1998, respectively. The first-in,
first-out ("FIFO") method is principally used for the remainder.
 
Property and Equipment--Property and equipment are stated at cost. Depreciation
is provided using the straight-line method for financial reporting purposes and
accelerated method for income tax reporting purposes over the estimated useful
lives of the assets, generally five to thirty years.
 
Investments--Investments in affiliates and corporate joint ventures which
represent a 20% to 50% equity interest are accounted for under the equity
method. Investments representing less than a 20% interest are carried at the
lower of cost or net realizable value.
 
Intangible Assets--Intangible assets primarily represent costs incurred to
acquire and/or establish patents, trademarks and process technology. These
costs are being amortized on a straight-line basis over the estimated useful
lives of the assets, generally five years. The amortization period begins with
the initial introduction of the underlying product to the market in order to
properly match revenue and expense. The Company reviews the carrying value of
intangible assets for impairment based on undiscounted cash flows whenever
events or changes in circumstances occur which might indicate that the carrying
amount might not be recoverable.
 
Deferred Financing Costs--Deferred financing costs represent costs associated
with the issuance of debt. These costs are being amortized using the effective
interest method over the life of the related debt issue.
 
Product Warranties--The Company provides the customer with a warranty from the
date of purchase. Estimated warranty obligations are recorded based on actual
claims experience.
 
Income Taxes--Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes. The
Company's results are included in the consolidated U.S. income tax return of
Cortelco Systems Holding Corporation. Income taxes are not provided on the
unremitted earnings of the Company's foreign subsidiaries and foreign joint
ventures since it is the Company's intention to continue to reinvest these
earnings.
 
Revenue Recognition--Revenues are recognized at the time products are shipped
or when title passes. Net sales is comprised of sales reduced by related sales
allowances. Revenues from cellular airtime are recognized when earned based on
cellular airtime contracts. The Company receives sales commissions on certain
transactions with the Puerto Rico Telephone Company. These commissions are
recorded as cellular airtime in the accompanying financial statements.
 
Cellular Telephone Equipment Deferred Acquisition Costs--The Company offers
commissions to dealers, and discounts to customers, on the sale of cellular
telephone equipment that is part of a simultaneous leasing of cellular
telephone service. These commissions and discounts are deferred and amortized
to income over the life of each contract, which usually ranges from one to
three years.
 
Allocation of Certain Shared Expenses--The accompanying financial statements
include the assets, liabilities, revenues and expenses specifically
identifiable with the Company as well as certain allocated expenses for
services provided by CSHC and CII. The costs have been allocated using formulas
including estimates of effort expended and sales. The financial statements may
not necessarily reflect the assets and liabilities and results of operations of
the Company had it been operated as a stand-alone entity.
 
Medical Care and Disability Benefit Plans--The Company is self-insured with
respect to certain medical and disability benefits offered to substantially all
employees through participation in an insurance plan with an affiliated
company. These

costs are charged against earnings in the period in which claims are incurred.
The Company does not provide benefits to retired employees.
 
Foreign Currency Translation--The assets and liabilities of the foreign joint
venture are translated at current exchange rates with the related translation
adjustments reported as a separate component of stockholders equity. Income
statement accounts are translated at the average exchange rate during the
period.
 
Earnings Per Share--The Company follows Statement of Financial Accounting
Standard ("SFAS") No. 128, "Earnings Per Share," which requires disclosure of
basic and diluted earnings per share ("EPS"). Basic EPS is computed by dividing
income available to common stockholders by the weighted average number of
common shares outstanding during the year. Diluted EPS is similar to basic EPS
except that the weighted average number of common shares outstanding is
increased to include the number of additional common shares that would have
been outstanding if the potentially dilutive common shares, such as options,
had been issued.
 
Reverse Stock Split--On February 24, 1999, the Company's board of directors
authorized a 1 for 10 reverse stock split of its common and preferred stock
effective for stockholders of record on March 1, 1999. The Company's board of
directors also approved an amendment to the Company's certificate of
incorporation to decrease the authorized common and preferred shares to
50,000,000 and 10,000,000, respectively, and to increase the par value per
common share from $.0001 to $.001. Shares outstanding and all per share amounts
in the accompanying financial statements have been restated to give effect to
the reverse stock split.
 
Fair Value of Financial Instruments--The carrying amounts of financial
instruments such as cash, accounts receivable, accounts payable and the
outstanding borrowings under the revolving credit agreement approximate their
fair value due to the short term nature of the instruments. Additionally, the
carrying value of the Company's investment in the foreign joint venture
discussed in Note 9 approximates fair value. As determined by an independent
third-party, the fair value of the Company's subordinated convertible debt
could not be practicably determined due to the lack of a quoted market and the
complex features of the security. Additional information pertinent to the debt
agreement is contained in Note 11.
 
Estimates--The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
Reclassifications--Certain amounts in the 1997 financial statements have been
reclassified to conform with the 1998 presentation.
 
New Accounting Standards--In June 1997, the Financial Accounting Standards
Board ("FASB") issued SFAS 130, "Reporting Comprehensive Income," which
established standards for reporting and display of comprehensive income and its
components and requires a separate statement to report the components of
comprehensive income for each period reported. The provisions of this statement
are effective for fiscal years beginning after December 15, 1997. Management
believes this statement may require expanded disclosure in the Company's
financial statements.
 
In June 1998, FASB issued SFAS 133, "Accounting for Derivative Instruments and
Hedging," which established accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. The provisions of this statement are
effective for fiscal years beginning after June 15, 1999. Management has not
evaluated what impact, if any, the adoption of this statement will have on the
disclosures in the Company's financial statements.

4. Discontinued Operations
 
Effective March 31, 1997 the Company distributed all of the outstanding common
stock of its subsidiary in the automatic call distribution business to the CSHC
stockholders. The net assets, results of operations and cash flows of Cortelco,
Inc. have been reported as discontinued operations in the accompanying

As of the date of the spin-off, the net assets of the Company's subsidiary in
the automatic call distributor business totalled $1,250,000 and this amount was
charged against retained earnings in the accompanying 1997 balance sheet to
reflect the distribution of the subsidiary's stock.
 
5. Major Customers and Concentrations of Credit Risk
 
Financial instruments which potentially subject the Company to a concentration
of credit risk consist principally of cash, trade accounts receivable and notes
receivable. The Company maintains its cash balances with large regional or
national financial institutions and has not experienced losses. The Company's
products are sold principally to dealers, value added resellers, national
accounts and the U.S. government. Approximately 38% of the Company's revenues
are generated within the Commonwealth of Puerto Rico. The Company's credit risk
is limited principally to trade accounts receivable. The Company performs
ongoing credit evaluations of its customers and generally does not require
collateral. No additional risk beyond amounts provided for collection losses is
believed inherent in the Company's trade accounts receivable.
 
6. Inventories
 
Inventories consist of the following:
 


                                                             ------------------
                                                                 1997      1998
                                                             --------  --------

  Total inventories......................................... $  5,849  $  6,256
                                                             ========  ========

 
In 1997, the liquidation of LIFO inventories decreased cost of revenues and
therefore decreased the net loss from continuing operations before taxes by
$200,000. In 1998, the liquidation of LIFO inventories decreased cost of
revenues and therefore decreased the net loss from continuing operations before
taxes by $84,000.

9. Investment in Joint Ventures
 
The Company has a $67,000 investment representing a 10% equity interest in a
Poland-based company (DTS/ZWUT) which will manufacture, sell and distribute
products designed and marketed by the Company. The Company accounts for its
interest in the joint venture at the lower of cost or net realizable value.
 
During 1996, the Company entered into an acquisition agreement with a Taiwanese
company ("Sea Union") whereby the Company has the option to acquire controlling
interests in several telecommunications joint ventures in mainland China over
an extended period of time in exchange for Company stock.
 
On August 11, 1997, the Company exercised its option to acquire a controlling
interest in one of the joint ventures. The Company acquired a 55% interest in
Heilongjiang Longhai Telecommunication Equipment Co., Ltd. ("Longhai") in
exchange for 95,343 shares of the Company's common stock valued at $67,000. The
acquisition was recorded under the

11. Debt
 
Cortelco Systems, Inc. Revolving Credit Facility--On July 31, 1997, CSI entered
into a new loan and security agreement with Foothill Capital (the "CSI Credit
Facility") which provides for borrowings based upon an asset formula involving
eligible accounts receivable and inventories, up to a maximum of $7,500,000,
including letters of credit, and expires in July 2001. At July 31, 1998, CSI
had outstanding borrowings under this facility of $2,353,000. The Company had
no outstanding letters of credit at July 31, 1998. The borrowings are
collateralized by substantially all the assets of the Company. The CSI Credit
Facility provides for interest at the reference rate plus the margin in effect,
which fluctuates during the term of the CSI Credit Facility, based on the
Company's satisfaction of certain minimum income requirements. At July 31, 1998
the effective interest rate was 8.875% (prime rate of 8.5% plus a margin of
 .375%). The CSI Credit Facility also provides for an annual facility fee equal
to .125% of the maximum borrowing base and an annual unused line fee equal to
 .375% based upon the average unused portion of the available credit.
 
The CSI Credit Facility also contains covenants which, among other matters,
limit the ability of the Company to incur indebtedness; merge, consolidate or
acquire or sell assets; pay dividends; or redeem or exchange capital stock. At
July 31, 1998 the Company was not in compliance with certain covenants
contained in the CSI Credit Facility. On March 30, 1999, the Company received a
waiver related to the covenants previously in default. On April 8, 1999, the
CSI Credit Facility was amended to pledge the outstanding common stock of CSPR.
 
Cortelco Puerto Rico, Inc. ("CPR") Revolving Credit Facility--On August 29,
1997, CPR entered into a new revolving line of credit agreement with Foothill
Capital (the "CPR Credit Facility") under which CPR may borrow up to
$1,500,000. The agreement provides for interest at a variable rate plus 1.25%
(9.75% at July 31, 1998). The CPR Credit Facility contains various restrictive
covenants and is secured by liens on accounts receivable and inventories as
well as a pledge of CPR's stock. At July 31, 1998, CPR had outstanding
borrowings under this facility of $386,000.
 
The CPR Credit Facility contains covenants which, among other matters limit the
ability of CPR to incur indebtedness; merge, consolidate or acquire or sell

CPR was not in compliance with certain covenants contained in the CPR Credit
Facility. On March 30, 1999, CPR received a waiver related to the covenants
previously in default.
 
On April 8, 1999, in connection with the assumption of the CPR Credit Facility
by CSPR (see Note 2), the CPR Credit Facility was amended to include as an
event of default a failure by CSHC to pledge the outstanding stock of CII to
the lender on or before May 28, 1999, as contemplated by CII's credit facility
with the lender.

(1) The outstanding balance of $3,000,000 represents borrowings under a
    subordinated note agreement dated July 31, 1997 with ChinaVest IV, L.P. The
    note matures on July 31, 2002 and is convertible into shares of the
    Company's Series A Convertible Preferred Stock based on a conversion price
    determined by a formula defined in the agreement, which is based on the
    Company's audited net income for the fiscal year ended July 31, 1998. Based
    on the conversion price formula, the holder can convert $686,000 of
    principal to 1,463,206 shares of Series A Convertible Preferred Stock. The
    holder has the option to convert the note at any time subsequent to July
    31, 1998. The agreement provides for interest at the rate of 8% annually.
    Upon conversion, the accrued interest on the principal amount converted by
    the holder is payable within sixty days following the date of conversion.
    The Company's Series A Convertible Preferred Stock has full voting rights
    and is convertible into common shares at any time.
  The agreement also contains covenants which, among other matters, limit the
  ability of the Company to merge, consolidate, acquire, or sell assets. At
  July 31, 1998, the Company was not in compliance with a covenant contained
  in the agreement. On April 5, 1999, the Company received a waiver related
  to the covenant previously in default. Additionally on April 5, 1999, the
  holder of the subordinated note provided their consent to a series of
  transactions, including the merger with CSPR and the reverse stock split
  discussed in Note 1 and the repurchase of common stock from CSHC in partial
  settlement of the outstanding note receivable (see Note 15).
(2) The outstanding balance at July 31, 1997 represents borrowings by CPR under
    a term loan agreement bearing interest at an annual rate of 9.85%. On
    August 29, 1997, the agreement was refinanced. The new agreement bears
    interest at a fixed rate of 10% and is due in monthly installments of
    principal and interest totalling $28,170 through September 1, 2002.
    Subsequent to September 1, 2002, the remaining principal balance will be
    negotiated for a period of five additional years. The agreement is
    collateralized by certain property.

$540,000, $526,000, and $446,000, respectively, which included $46,000,
$137,000, and $137,000, respectively, rent charged by CII for the sharing of
warehouse space.
 
13. Income Taxes
 
The Company's current taxable income has historically been included in the
consolidated income tax return of CSHC. There does not currently exist a tax
sharing agreement for allocating income taxes. The consolidated provision or
benefit is allocated proportionately between the subsidiaries of CSHC based on
the contribution of each company in the consolidated federal tax return as if
each company calculated its tax on a separate return basis.
 
The financial statements of the Company do not include a provision (benefit)
for income taxes for 1997 and 1998 due to cumulative net operating losses.
 
The components of income tax expense attributable to continuing operations for
1996 are as follows:

Income taxes are not provided for the undistributed earnings of the foreign
joint venture as such earnings are intended to be permanently reinvested. Such
earnings would become taxable upon the sale or liquidation or upon the
remittance of dividends. Accumulated undistributed earnings on which U.S. taxes
have not been provided are approximately $66,000.
 
The deferred tax effects of the Company's principal temporary differences at
July 31, 1997 and 1998 are as follows:

14. Stock Options
 
During 1998, the Board of Directors approved the adoption of the 1997 Equity
Incentive Plan (the "Plan") which permits the granting of incentive stock
options, supplemental stock options, stock bonuses, and restricted stock
purchase agreements to officers, directors and key employees of the Company and
to non-employee consultants. At July 31, 1998, 250,000 shares of the Company's
common stock were reserved for issuance under the terms of the Plan. Incentive
stock options are granted only to employees and are issued at prices not less
than 100% of the fair market value of the stock at the date of grant. The
options vest over a four-year period and the term of any option shall not be
greater than ten years from the date of grant. Stock bonuses and restricted
stock purchase agreements are granted only to directors, officers, or employees
of or consultants to the Company and are issued at prices not less than 85% of
the fair market value of the stock at the date of grant. During 1998, 139,311
options were granted with exercise prices ranging from $.70 to $1.00 per share
and remain outstanding at July 31, 1998. No compensation expense related to
stock option grants was recorded during 1998 as the option exercise prices were
equal to or greater than fair market value on the date of grant.
 
The status of the Company's stock option plan is as follows:
 

                                                                   ------------

The options outstanding at July 31, 1998 are exercisable at prices ranging from
$.70 to $1.00 per share. The weighted average remaining contractual life of all
outstanding options was 9.81 years at July 31, 1998.
 
The Company accounts for stock-based compensation using the intrinsic value
method prescribed by Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," under which no compensation cost for stock
options is recognized for options granted at or above fair market value. Had
compensation expense been determined based upon fair values at the grant dates
in accordance with SFAS No. 123, "Accounting for Stock-Based Compensation," the
Company's net income and earnings per share would not have been different as
the fair value of the options was determined to be zero on the applicable dates
of grant.
 
15. Related Parties
 
As discussed in Note 1, certain expenses reflected in the financial statements
include allocations of expenses from CSHC and CII. These allocations include:
insurance, computer maintenance, general warehousing expenses, and salesmen
expenses.
 
During 1997, CSHC incurred certain costs on behalf of CSHC's subsidiaries.
Management of CSHC allocated these costs proportionately among the subsidiaries
based on estimates of effort expended and sales. As a result, the Company
incurred management fee expense of $406,000 for the year ended July 31, 1997.
 
During 1998, certain costs were incurred by CSI on behalf of CSHC and the

18. Commitments and Contingencies
 
At July 31, 1998 the stock of the Company was pledged as collateral under a
$3,600,000 note payable from CSHC to a corporation. The note matured in
September 1998 and was secured by the outstanding common stock of the Company
and a personal guaranty of the single largest stockholder of CSHC. CSHC did not
make the scheduled payment due in September 1998. On February 25, 1999, CSHC
entered a consent agreement with the corporation whereby the stock of CSI was
released from the original pledge agreement in order to allow the CSI spin-off
discussed in Note 2. Additionally, the corporation agreed not to declare an
event of default. In exchange for the corporation's consent, CSHC remitted
$1,000,000 of the amount outstanding and agreed to a revised repayment
schedule. In connection with the transaction, CSHC's single largest stockholder
loaned CSHC $1,000,000.

                    Years Ended July 31, 1996, 1997 and 1998
 
The Company is involved in various matters of litigation, claims, and
assessments arising in the ordinary course of business. In the opinion of
management, the eventual disposition of these matters will not have a material
adverse effect on the financial statements.
 
19. Earnings Per Share
 
The computations of basic and diluted earnings per share for each year were as
follows:
 


                                             ---------------------------------
                                                   1996        1997        1998
                                             ---------   ---------   ---------
                                                            
Dollars in thousands, except per share data
Income (loss) from continuing operations...  $      932  $   (1,524) $     (133)
Discontinued operations....................      (1,207)       (515)        --
                                             ---------   ---------   ---------
 Income (loss) available to common
  shareholders.............................        (275)     (2,039)       (133)
Weighted average shares outstanding........       3,825       3,825       3,918
                                             ---------   ---------   ---------
 Basic and diluted earnings per share......  $    (0.07) $    (0.53) $    (0.03)
                                             =========   =========   =========

 
Options to purchase 139,311 shares of common stock were outstanding at July 31,
1998 but were not included in the computation of the diluted earnings per share
because the options' exercise price was equal to or greater than the average
market price of the common shares. Additionally, at July 31, 1997 and 1998,
$686,000 of convertible subordinated debt was convertible into 1,463,206 shares
of convertible preferred stock which was convertible into 1,434,894 shares of
common stock. All of these potential common shares were excluded from the
computation of diluted earnings per share for 1997 and 1998 because their
inclusion would have had an antidilutive effect on earnings per share.
 
20. Subsequent Events
 
On February 24, 1999, the Company's Board of Directors declared a dividend of
$2,216,514 payable to the stockholders (CSHC and Sea Union) of record on
February 26, 1999. Approximately $1,957,000 of the dividend declared is payable
upon certain events occurring in the future. The remaining amount of the
dividend declaration primarily relates to the distribution of the non-interest
bearing note receivable from an officer/director to CSHC. As the Company has a
retained deficit, the dividend is recorded as a return of capital. The dividend
has been reflected in the financial statements as if declared on July 31, 1998.
 
On April 5, 1999, the Company's Board of Directors declared a stock dividend of
195,685 shares of the Company's common stock to stockholders of record on April
5, 1999. The dividend was charged to the accumulated deficit in the amount of
$1,956,850, which was based on the fair value of the Company's common stock as
determined by the Board of Directors. The stock dividend has been reflected in
the financial statements as if declared on July 31, 1998.
 
On April 5, 1999, the Company received 250,000 shares of its common stock from
CSHC in exchange for a $2,500,000 reduction of the outstanding note receivable
balance.
 
On April 8, 1999, previous to the merger discussed in Note 1, CSPR declared a
dividend of $700,000 payable to the stockholder (CSHC) of record on April 8,
1999, payable upon certain events occurring in the future. The dividend has
been reflected in the financial statements as if declared on July 31, 1998.
 
Subsequent to year-end, the Company entered into a letter of intent agreement
to merge with an affiliated company, BCS Technologies, Inc.

1. Financial Statement Presentation
 
The accompanying consolidated financial statements have been prepared by the
Company, without audit. It is management's opinion that these statements
include all adjustments, consisting of only normal recurring adjustments,
necessary to present fairly the financial position, results of operations, and
cash flows as of January 31, 1999 and for all periods presented. The results
for the six months ended January 31, 1998 and 1999 are not necessarily
indicative of the results that may be expected for the full year.
 
Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. It is suggested that these
consolidated financial statements be read in conjunction with the consolidated
financial statements and notes thereto as of July 31, 1997 and 1998 and for
each of the three years in the period ended July 31, 1998.

                          Independent Auditors' Report
 
Board of Directors and Stockholders
BCS Technologies, Inc.
Englewood, Colorado
 
We have audited the accompanying balance sheets of BCS Technologies, Inc. as of
July 31, 1997 and 1998, and the related statements of operations, changes in
stockholders' equity and cash flows for the eleven months ended July 31, 1997
and the year ended July 31, 1998. These financial statements are the
responsibility of the Corporation's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of BCS Technologies, Inc. as of
July 31, 1997 and 1998, and the results of its operations and its cash flows
for the eleven months ended July 31, 1997 and the year ended July 31, 1998 in
conformity with generally accepted accounting principles.

1. Organization
 
Organization
BCS Technologies, Inc. (the "Company") is a corporation formed through a series
of transactions which culminated in a merger between Business Communications
Systems, Inc. and Cortelco, Inc. Cortelco, Inc., Cortelco Systems, Inc. and
Cortelco Systems Holding Corporation are all entities related through common
stock ownership. Business Communications Systems, Inc. was an unrelated
corporation prior to the merger.
 
On April 1, 1997, Cortelco, Inc., a wholly owned subsidiary of Cortelco
Systems, Inc. in the automatic call distribution products business, was spun
off to the stockholders of Cortelco Systems Holding Corporation. Immediately
afterwards, Cortelco, Inc. was merged with Business Communications Systems,
Inc., the accounting acquiror. Business Communications Systems, Inc. changed
its name to BCS Technologies, Inc.
 
Description of Business
The Company was originally founded in 1985 and operates from offices in
Englewood, Colorado and a 23,000 square foot facility located in Georgia. The
Company is engaged in the development, sales, manufacturing and distribution of
electronic communication devices throughout the United States.
 
Business Activities
The Company is a corporation organized under the laws of the State of Delaware
for the purpose of the sale and servicing of electronic communication devices
throughout the United States.
 
2. Summary of Significant Accounting Policies
 
Use of Estimates in Preparing Financial Statements
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
Cash and Cash Equivalents
For purposes of the statement of cash flows, the Company considers all highly
liquid investments purchased with a maturity of three months or less to be cash
equivalents. Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and temporary cash
investments. At times, cash balances held at financial institutions were in
excess of FDIC insurance limits. The Company limits the amount of credit
exposure to any one financial institution. The Company believes no significant
concentration of credit risk exists with respect to these cash investments.
 
Revenue Recognition
The Company recognizes revenues from system and product sales when title passes
to the customer. Revenues from prepaid maintenance contracts are recognized
ratably over the terms of the contracts. Revenues from the sales of systems
accounted for approximately 32%, 53%, 37%, and 75% for the eleven months ended
July 31, 1997, the year ended July 31, 1998, and the six months ended January
31, 1998 and 1999. The Company generates the remainder of its revenue from
parts sales and system maintenance.
 
Accounts Receivable
The Company charges off all known uncollectible accounts on a current basis. No
reserve for uncollectible accounts is required, as any accounts which are
considered doubtful are not considered material to the financial statements.

                             BCS Technologies, Inc.
 
                   Notes to Financial Statements--(Continued)
 
Inventories
The Company uses the lower of first-in, first-out ("FIFO") cost or market in
valuing inventories.
 
Depreciation
The Company provides for depreciation of property and equipment using straight-
line and accelerated methods for financial and income tax reporting purposes
over the estimated useful lives of the assets, which is generally fifteen years
for leasehold improvements, five years for machinery and equipment, five to
seven years for furniture and fixtures and vehicles and three years for
computer software.
 
Product Warranties
The Company provides the customer with a warranty from the date of purchase.
Estimated warranty obligations are recorded based on actual claims experience.
 
Income Taxes
Income tax expense is based on reported income before income taxes. Deferred
income taxes reflect the temporary difference between assets and liabilities
recognized for financial reporting and such amounts recognized for tax purposes
which requires recognition of deferred income tax assets and liabilities.
Deferred income tax assets and liabilities are determined based on the
differences between the financial statement and tax basis of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. A valuation allowance is recognized if it
is anticipated that some or all of a deferred income tax asset may not be
realized.
 
Advertising
Advertising costs are charged to operations in the year incurred. The Company
expended $170,426 for the eleven months ended July 31, 1997, $117,912 for the
year ended July 31, 1998, and $43,936 and $57,595 for the six months ended
January 31, 1997 and 1998, respectively.
 
Interim Financial Statements
The financial statements for the six months ended January 31, 1998 and 1999 are
unaudited, but in the opinion of management, include all adjustments necessary
to fairly state the results therein, such adjustments being of a normal,
recurring nature. Operating results for the six months ended January 31, 1999
are not necessarily indicative of the results that may be expected for the
fiscal year ending July 31, 1999. All January 31, 1998 and 1999 data presented
in these footnotes is unaudited.
 
Stock Option Plans
The Company utilizes Statement of Financial Accounting Standards No. 123 (FAS
123), "Accounting for Stock-Based Compensation". The Statement defines a fair
value based method of accounting for stock options or similar equity
instrument. FAS 123 allows an entity to continue to measure compensation cost
for employee stock option plans using the intrinsic value based method of
accounting prescribed by Accounting Principles Board Opinion (APB) No. 25,
which was elected by the Company. Accordingly, the Company must make certain
pro forma disclosures as if the fair value based method had been applied.
 
Earnings (Loss) Per Common Share
Basic earnings per share is computed by dividing income available to common
stockholders by the weighted-average number of common shares outstanding for
the period. Dilutive earnings per share reflects the potential dilution that
could occur if dilutive securities, stock options, were exercised.

Additional Stock Plan Information.
Since the Company continues to account for its stock-based awards to employees
using the intrinsic value method in accordance with APB No. 25, FAS 123,
"Accounting for Stock-Based Compensation," requires the disclosure of pro forma
net income (loss) and earnings (loss) per share had the Company adopted the
fair value method as of the beginning of 1995. Under FAS 123, the fair value of
stock-based awards to employees is calculated through the use of option pricing
models, even though such models were developed to estimate the fair value of
freely tradable, fully transferable options
 
                                      F-34

without vesting restrictions, which significantly differ from the Company's
stock option awards. These models also require subjective assumptions,
including future stock price volatility and expected time to exercise, which
greatly affect the calculated values. The Company's fair value calculations on
stock-based awards under the stock plans were made using the Black-Scholes
option pricing model with the following weighted average assumptions: expected
life, 8 years from the date of grant in 1997 and 10 years from the date of
grant in 1999; stock volatility, 0% in 1997 and in 1999; risk-free interest
rate, 6.75% in 1997 and 5.0% in 1999 and no dividends during the expected term.
The Company's calculations are based on a single option award valuation
approach, and forfeitures are recognized as they occur. If the computed fair
values of the 1997 and 1999 awards had been amortized to expense over the
vesting period of the awards, the effect on pro forma net income (loss) would
have been insignificant.

Prior to April 2, 1997, the Company had elected under Subchapter S of the
Internal Revenue Code to have its income taxed directly to its stockholders.
The 1997 provision for income taxes includes only the taxable income from April
2, 1997 through July 31, 1997. Pro forma net income and earnings per share have
been determined assuming the Company had been taxed under Subchapter C of the
Internal Revenue Code for federal and state purposes for 1997.
 
The following table reconciles the provision for income taxes at the U.S.
Statutory rate to that in the financial statements for 1998:

                   Notes to Financial Statements--(Continued)
 
As a result of the merger, the Company has a net operating loss carryforward of
approximately $8,250,000 available to offset Georgia state income taxes. The
financial statements and disclosures do not include recognition of
approximately $495,000 of deferred income tax benefit due to the significant
uncertainty of its future realization.
 
12. Earnings (Loss) Per Common Share
 
Outstanding stock options to purchase 1,383,542, 1,364,750, 1,383,542 and
1,489,750 shares of common stock were not included in the computation of
diluted earnings (loss) per common share for the eleven months ended July 31,
1997, the year ended July 31, 1998, and the six months ended January 31, 1998
and 1999. The effect of including the stock options would be antidilutive or
the stock options were exercisable from shares owned by existing stockholders.

BCS Technologies, Inc. had occurred as of August 1, 1997. The following pro
forma consolidated balance sheet data presents the unaudited pro forma
financial condition of the Company as if the acquisition of BCS Technologies,
Inc. had occurred as of January 31, 1999. The pro forma financial data reflects
adjustments to the historical financial statements of Cortelco and BCS
Technologies, Inc., that (1) reflect the purchase method of accounting for the
acquisition of BCS, and (2) eliminate the results of operations and related
assets and liabilities not acquired from the merger with Cortelco Systems
Puerto Rico.
 
The pro forma, as adjusted, financial information gives effect, additionally,
to (1) the conversion of $686,000 of convertible debt into 1,434,894 shares of
common stock upon the closing of this offering, and (2) this offering and the
uses of proceeds from this offering.

       Notes to Pro Forma Consolidated Financial Information (Unaudited)
 
1. Basis of Presentation
 
The pro forma consolidated statements of operations data for the year ended
July 31, 1998 and the six month periods ended January 31, 1998 and 1999
represent the unaudited pro forma operating results as if the acquisition of
BCS Technologies, Inc. ("BCS") had occurred as of August 1, 1997. The pro forma
consolidated balance sheet data presents the unaudited pro forma financial
condition of the Company as if the acquisition of BCS had occurred as of
January 31, 1999. The pro forma financial data reflects adjustments to the
historical financial statements of Cortelco Systems ("the Company") and BCS,
that (1) reflect the purchase method of accounting for the acquisition of BCS,
and (2) eliminate the results of operations and related assets and liabilities
not acquired from the merger with Cortelco Systems Puerto Rico.
 
The pro forma, as adjusted, financial information gives effect, additionally,
to (1) the conversion of $686,000 of convertible debt into 1,434,894 shares of
common stock upon the closing of the offering, and (2) the offering and the
uses of proceeds thereof.
 
The pro forma financial data does not purport to represent what the Company's
financial position or results of operations actually would have been had the
transactions occurred on the dates indicated, or to project the Company's
financial position or results of operations at any future date or for any
future period. The following pro forma financial data should be read in
conjunction with Cortelco's consolidated financial statements and related
notes, BCS' financial statements and related notes and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" which is
included elsewhere.

Item 14. Indemnification of Officers and Directors.
 
Under Section 145 of the Delaware General Corporation Law, we have broad powers
to indemnify our directors and officers against liabilities they may incur in
such capacities, including liabilities under the Securities Act.
 
Our certificate of incorporation provides for the elimination of liability for
monetary damages for breach of the directors' fiduciary duty of care to
Cortelco and its stockholders. These provisions do not eliminate the directors'
duty of care and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available under
Delaware law. In addition, each director will continue to be subject to
liability for breach of the director's duty of loyalty to Cortelco, for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for any transaction from which the director derived an
improper personal benefit, and for payment of dividends or approval of stock
repurchases or redemptions that are unlawful under Delaware law. The provision
does not affect a director's responsibilities under any other laws, such as the
federal securities laws or state or federal environmental laws.
 
We expect to enter into agreements with our directors and officers that require
us to indemnify such persons against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred (including expenses of a
derivative action) in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or officer of Cortelco or any of its
affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of Cortelco and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The
indemnification agreements also set forth certain procedures that will apply in
the event of a claim for indemnification thereunder.
 
The Underwriting Agreement filed as Exhibit 1.1 to this registration statement
provides for indemnification by the underwriters of Cortelco and its officers
and directors for certain liabilities arising under the Securities Act or
otherwise.
 
Item 15. Recent Sales of Unregistered Securities.
 
Since April 1996, we have sold and issued the following unregistered
securities:
 
(1) In July 1997, we issued a convertible promissory note in the aggregate
    principal amount of $3,000,000 to ChinaVest IV, L.P.
 
(2) In August 1997, we sold 95,343 shares of common stock to an investor in
    exchange for an interest in the Longhai joint venture.
 
(3) In April 1999, we issued 3,969,681 shares of common stock to stockholders
    of BCS Technologies, Inc. and assumed options covering 94,279 shares of
    common stock under the BCS 1977 Incentive Plan in connection with the
    acquisition of BCS. We issued 553,880 shares of common stock to Cortelco
    Systems Holding Corporation in connection with the merger with Cortelco
    Systems Puerto Rico.
 
                                      II-1

 
(4) Since April 1998, we have granted incentive stock options to employees,
    directors and consultants under our 1997 Equity Incentive Plan covering an
    aggregate of 338,826 shares of common stock, at an average exercise price
    of $3.76. No options have been exercised under the 1997 Equity Incentive
    Plan.
 
(5) Since April 1999, we have granted incentive stock options to employees,
    directors and consultants under our 1999 Equity Incentive Plan covering an
    aggregate of 270,000 shares of common stock, at an average exercise price
    of $11.75. No options have been exercised under the 1999 Equity Incentive
    Plan.
 
The sales and issuances of securities in the transactions described in
paragraphs (1) through (3) were deemed to be exempt from registration under the
Securities Act by virtue of Section 4(2) and/or Regulation D promulgated under
the Securities Act. The purchasers in each case represented their intention to
acquire the securities for investment only and not with a view to the
distribution thereof. Appropriate legends are affixed to the stock certificates
issued in such transactions. Similar legends were imposed in connection with
any subsequent sales of any such securities. All recipients either received
adequate information about Cortelco or had access, through employment or other
relationships, to such information.
 
The sales and issuance of securities in the transaction described in paragraphs
(4) and (5) above were deemed to be exempt from registration under the
Securities Act by virtue of Rule 701 promulgated thereunder in that they were
offered and sold either pursuant to written compensatory benefit plans or
pursuant to a written contract relating to compensation, as provided by Rule
701.

Item 17. Undertakings.
 
We undertake to provide to the underwriters at the closing specified in the
Underwriting Agreement certificates in such denominations and registered in
such names as required by the underwriters to permit prompt delivery to each
purchaser.
 
Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of Cortelco
pursuant to the foregoing provisions or otherwise, Cortelco has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Cortelco of expenses
incurred or paid by a director, officer or controlling person of Cortelco in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, Cortelco will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
We hereby undertake that: (i) for purposes of determining any liability under
the Securities Act, the information omitted from the form of prospectus filed
as part of this registration statement in reliance upon Rule 430A and contained
in a form of prospectus filed by Cortelco pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time the Commission declared it effective, and (ii) for the
purpose of determining any liability under the Securities Act, each post-
effective amendment that contains a form of prospectus shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
