                                   SCHEDULE TO

         This Amendment amends and supplements the Tender Offer Statement on
Schedule TO (as amended and supplemented, the "Schedule TO") initially filed on
November 13, 2002 by Arizona Acquisition Corp., a Delaware corporation (the
"Purchaser") and a wholly owned subsidiary of Enghouse Systems Limited, an
Ontario corporation ("Enghouse"), in connection with the offer by the Purchaser
to purchase all of the outstanding common shares, $.01 par value per share
("Shares"), of Syntellect Inc., a Delaware corporation ("Syntellect"), that are
not already owned by Syntellect, the Purchaser or Enghouse, at $0.72 per Share,
net to the seller in cash, without interest, upon the terms and subject to the
conditions set forth in the Offer to Purchase dated November 13, 2002, a copy of
which is attached as Exhibit (a)(1), and in the related Letter of Transmittal, a
copy of which is attached as Exhibit (a)(2). Capitalized terms used herein and
not otherwise defined shall have the meanings set forth in the Schedule TO.

ITEMS 1 - 6, 8, 9, 11.

         The response to the question "Have any stockholders of Syntellect
agreed to tender their shares in the offer?" in the Summary Term Sheet included
in the Offer to Purchase is amended by adding the following:

         "Syntellect has informed us that its directors and executive officers
own an aggregate of 948,125 shares (including exercisable options to purchase
441,960 shares, none of which are exercisable at prices below $0.72 per share),
or approximately 8% of the outstanding shares (approximately 4%, not counting
options)."

         The seventh paragraph in the Introduction to the Offer to Purchase is
restated as follows:

         "Pursuant to the Tender and Voting Agreement, dated as of November 5,
2002 (the "Tender and Voting Agreement"), among Syntellect, Enghouse and
Geoffrey Nixon, Mission Partners, L.P., Liberty Nominees Limited, Horizon
Offshore, Ltd., Mayfair Capital Fund, L.P., MCM Profit Sharing Plan CSFB-MCM
Associated Ltd, MCM Associates, Ltd., Wynnefield Partners Small Cap Value, L.P.,
Wynnefield Partners Small Cap Value, L.P. I, Wynnefield Small Cap Value Offshore
Fund, Ltd., Wynnefield Capital Management, L.L.C. and Wynnefield Capital, Inc.
(the "Holders"), the Holders agreed to tender all of their Shares to the
Purchaser in the Offer."

         The eleventh paragraph in the Introduction to the Offer to Purchase is
hereby amended and supplemented by adding the following:

         "Enghouse owns 246,250 Shares, or approximately 2% of the outstanding
Shares. The directors and executive officers of Syntellect own 948,125 Shares
(including exercisable options to purchase 441,960 Shares), or approximately 8%
of the outstanding Shares. The Holders own 1,708,720 Shares, or approximately
15% of the outstanding Shares. If all such Shares are tendered, the Purchaser
believes the Minimum Condition would be satisfied if approximately 3,002,462
additional Shares (or approximately 25% of the outstanding Shares) are validly
tendered.

         "None of the exercisable options held by Syntellect directors and
executive officers are exercisable at prices below $0.72 per Share. If the
Shares underlying these options are not tendered, but all other Shares held by
Enghouse, the Holders and Syntellect's directors and executive officers are
tendered, the Purchaser believes the Minimum Condition would be satisfied if
approximately 3,223,442 additional Shares (or approximately 28% of the
outstanding Shares) are validly tendered."

         The sixth paragraph under Section 1 of the Offer to Purchase is amended
by adding the following:

         "If the Purchaser determines to provide a Subsequent Offering Period,
the Purchaser will issue a press release to a national news service announcing
the Subsequent Offering Period no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date and
immediately begin the Subsequent Offering Period."



         The penultimate paragraph under Section 2 of the Offer to Purchase is
restated as follows:

         "If any tendered Shares are not accepted for payment for any reason
pursuant to the terms and conditions of the Offer, or if Share Certificates are
submitted evidencing more Shares than are tendered, Share Certificates
evidencing unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedure set forth in Section 3 (Procedures for Accepting the Offer and
Tendering Shares) of this Offer to Purchase, such Shares will be credited to an
account maintained at the Book-Entry Transfer Facility), promptly following the
expiration or termination of the Offer."

         The title of Section 5 of the Offer to Purchase is hereby restated to
be "Material United States Federal Income Tax Consequences." The second sentence
of the first paragraph of Section 5 is hereby restated as follows:

         "The discussion does not purport to consider all aspects of United
States federal income taxation that might be relevant to stockholders of
Syntellect."

         Section 8 of the Offer to Purchase is hereby amended by adding the
following:

         "Enghouse presently owns 246,250 Shares. The Tender and Voting
Agreement covers 1,708,720 Shares. The Stock Option Agreement covers up to
2,262,461 Shares. The Purchaser Option covers up to 13,630,848 Shares. These
options are mutually exclusive and may not exercised prior to the Expiration
Date and therefore may not be used to satisfy the Minimum Condition. The maximum
aggregate number of Shares described in this paragraph is 15,585,818,
constituting 62.3% of the outstanding Shares. Enghouse and the Purchaser may be
deemed to beneficially own all such Shares. Enghouse and the Purchaser disclaim
beneficial ownership of the Shares covered by the Tender and Voting Agreement,
the Stock Option Agreement and the Purchaser Option."

         The first paragraph under Section 10 of the Offer to Purchase is hereby
restated as follows:

         "Enghouse continually evaluates strategic acquisition opportunities to
accelerate growth and to enter new vertical markets and accordingly monitors
dozens of companies at any given time. In furtherance of that goal, Enghouse
identified Syntellect as a possible acquisition candidate and arranged a meeting
with Syntellect for August 20, 2002. On August 20, management of Syntellect,
together with Alliant, held a meeting with Stephen J. Sadler, Chairman and Chief
Executive Officer of Enghouse, at which time Syntellect provided general
industry and company information. Enghouse indicated its interest in pursuing
further discussions regarding Syntellect in a letter to Alliant dated August 29,
2002. In that letter, Enghouse indicated a price of $0.72 per Share, subject to
due diligence and other conditions. Following the initial meeting, through
September and October, the parties held a number of discussions regarding a
possible strategic transaction and conducted due diligence with respect to one
another. In September, following receipt of the letter, Syntellect requested
that Enghouse increase the amount of its offer. Following further discussions,
Syntellect and Enghouse discussed a price of $0.84 per Share, contingent on
completion of due diligence and receipt of Syntellect's third quarter results."

         A new third paragraph is hereby added to Section 10 of the Offer to
Purchase, as follows:

         "Syntellect announced third quarter results on October 23, 2002, which
included lower revenues than expected and a $0.07 per Share loss for the quarter
ended September 30, 2002. After consideration of the third quarter operating
results and evaluation of its Syntellect due diligence, Enghouse maintained its
offer of $0.72 per Share. No further offers or counteroffers were made."



         Section 15 of the Offer to Purchase is hereby amended and supplemented
by adding the following:

         "The Purchaser will not assert a condition if the failure to be
satisfied of such condition is the result of actions or inactions by Enghouse or
its subsidiaries. All conditions to the Offer, other than those dependent upon
the receipt of any necessary government approvals, will be asserted, satisfied
or waived on or before the Expiration Date."

         Section 17 of the Offer to Purchase is hereby amended and supplemented
by adding the following:

         "Any stockholder who holds Shares on the date of the making of a demand
described below, who continuously holds such Shares through the effective date
of the Merger, who has otherwise complied with the provisions of Section 262 of
the DGCL and who has neither voted in favor of the Merger nor consented thereto
in writing shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's Shares as provided in Section 262 of the DGCL.
Only stockholders of record may exercise appraisal rights.

         "If the Merger is to be submitted for approval at a meeting of
stockholders, Syntellect, not less than 20 days prior to the meeting, shall
notify each stockholder who was such on the record date for such meeting that
appraisal rights are available for any or all of the Shares. Each stockholder
electing to demand the appraisal of his Shares shall deliver to Syntellect,
before the taking of the vote on the Merger, a written demand for appraisal of
his Shares. A proxy or vote against the Merger shall not constitute such a
demand.

         "If the Merger was approved pursuant to the short-form merger
provisions of Delaware law, Syntellect, either before the effective date of the
Merger or within ten days thereafter, shall notify each of the holders of Shares
who are entitled to appraisal rights of the approval of the Merger and that
appraisal rights are available. Any stockholder entitled to appraisal rights
may, within 20 days after the date of mailing of such notice, demand in writing
from Syntellect the appraisal of such holder's Shares.

         "Within 120 days after the effective date of the Merger, Syntellect or
any stockholder who is entitled to appraisal rights may file a petition in the
Court of Chancery demanding a determination of the value of the Shares of all
such stockholders. Notwithstanding the foregoing, at any time within 60 days
after the effective date of the Merger, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
Merger.

         "The foregoing summary of the rights of dissenting holders of Shares
under Delaware law does not purport to be a complete statement of the procedures
to be followed by holders of Shares desiring to exercise any dissenters' rights
under Delaware law. The preservation and exercise of dissenters' rights require
strict adherence to the applicable provisions of Delaware law. The relevant
provisions of Delaware law are complex and technical in nature. Stockholders
desiring to exercise their appraisal rights may wish to consult counsel, since
the failure to comply strictly with these provisions will result in the loss of
their appraisal rights. Shares tendered in the Offer will not be entitled to
appraisal rights."

         After due inquiry and to the best of my knowledge and belief, I certify
