ITEM 3.01    NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE
             OR STANDARD; TRANSFER OF LISTING.

(a) On April 17, 2006, Ulticom, Inc. (the "Company") received a Staff
Determination letter from The NASDAQ Stock Market indicating that the Company is
not in compliance with NASDAQ Marketplace Rule 4310(c)(14) because the Company
did not timely file its Annual Report on Form 10-K for the fiscal year ended
January 31, 2006 with the Securities and Exchange Commission. The notice
provides that, as a result of the failure to timely make such filing, the
Company's common stock will be delisted from The NASDAQ National Market, subject
to the Company's ability to appeal for review of such action by the NASDAQ
Listing Qualifications Panel (the "Panel"). The Company will request a hearing
before the Panel to review the Staff Determination letter and to seek continued
listing of its stock for a period pending completion of its review and the
preparation and filing of the requisite report. Under NASDAQ Marketplace Rules,
a request for a hearing stays the delisting action pending the issuance of a
written determination by the Panel. There can be no assurance that the Panel
will grant the Company's request for continued listing. Pending a decision by
the Panel, the Company's common stock will remain listed on The NASDAQ National
Market.

As previously announced by the Company, it did not file on April 17, 2006, the
due date, its Annual Report on Form 10-K for the year ended January 31, 2006
pending completion of a review by its Audit Committee of its stock option grants
and the completion of a review by the Company's majority shareholder, Comverse
Technology, Inc., of its stock option grants, some of which affect the Company's
financial statements. The review by the Company's Audit Committee is in its
final stages, and Ulticom believes that it will be able to release its Form 10-K
Annual Report for the year ended January 31, 2006 promptly after Comverse has
completed its review.

The Company issued a press release with regard to the notice it received from
NASDAQ on April 20, 2006, a copy of which is attached hereto as Exhibit 99.1 and
incorporated herein by reference.

Note: This Form 8-K contains "forward-looking statements" for purposes of the
Private Securities Litigation Reform Act of 1995 that involve risks and
uncertainties. There can be no assurances that forward-looking statements will
be achieved, and actual results could differ materially from forecasts and
estimates. Important factors that could cause actual results to differ
materially include: the results of the Audit Committee's review of matters
relating to the Company's stock option awards, including but not limited to the
accuracy of the stated grant dates of option awards and whether proper corporate
procedures were followed in connection with such awards; the results of
Comverse's review of its stock option awards as applicable to employees of the
Company; the impact of any restatement of the financial statements of the
Company or other actions that may be taken or required as a result of such
reviews; the Company's inability to file required reports with the Securities
and Exchange Commission; the risks that may be associated with potential claims
and proceedings relating to such matters, risk associated with the Company's
inability to meet the requirements of the NASDAQ Stock Market for continued
listing of the Company's shares; risks associated with the development and
acceptance of new products and product features; risks associated with the
Company's dependence on a limited number of customers for a significant
percentage of the Company's revenues; changes in the demand for the Company's
products; changes in capital spending among the Company's current and
prospective customers; aggressive competition that may force the Company to
reduce prices; risks associated with rapid technological changes in the
telecommunications industry; risks associated with making significant
investments in the expansion of the Company's business and with increased
expenditures; risks associated with holding a large proportion of the Company's
assets in cash equivalents and short-term investments; risks associated with the
Company's products being dependent upon their ability to operate on new hardware
and operating systems of other companies; risks associated with dependence on
sales of the Company's Signalware products; risks associated with future
networks not utilizing signaling systems and protocols that the Company's
products are designed to support; risks associated with the products having long
sales cycles and the limited ability to forecast the timing and amount of
product sales; risks associated with the integration of the Company's products
with those of equipment manufacturers and application developers and the
Company's ability to establish and maintain channel and marketing relationships
with leading equipment manufacturers and application developers; risks
associated with the Company's reliance on a limited number of independent
manufacturers to manufacture boards for the Company's products and on a limited
number of suppliers for board components; risks associated with becoming
subjected to, defending and resolving allegations or claims of infringement of
intellectual property rights; risks associated with others infringing on the


                                       2

Company's intellectual property rights and the inappropriate use by others of
the Company's proprietary technology; risks associated with the Company's
ability to retain existing personnel and recruit and retain qualified personnel;
risks associated with the increased difficulty in relying on equity incentive
programs to attract and retain talented employees and with any associated
increased employment costs; risks associated with rapidly changing technology
and the ability of the Company to introduce new products on a timely and
cost-effective basis; risks associated with changes in the competitive or
regulatory environment in which the Company operates; and other risks described
in the Company's filings with the Securities and Exchange Commission. These
risks and uncertainties, as well as others, are discussed in greater detail in
the filings of Ulticom with the Securities and Exchange Commission, including
our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on
Form 10-Q. All documents are available through the SEC's website at www.sec.gov
or from Ulticom's web site at www.ulticom.com. Ulticom makes no commitment to
revise or update any forward-looking statements in order to reflect events or
circumstances after the date any such statement is made.
