FOR IMMEDIATE RELEASE

Ulticom Announces Preliminary First Quarter Fiscal 2005 Results

Mount Laurel, New Jersey, May 2, 2005 - Ulticom, Inc. (NASDAQ: ULCM), a leading
provider of service-enabling signaling software for wireless, wireline, and
Internet communications, today announced preliminary results for the first
quarter of fiscal year 2005, which ended April 30, 2005. Ulticom anticipates
sales for the quarter to be approximately $14 million, resulting in earnings of
approximately $0.05 to $0.06 per diluted share.

"The lower than expected results for the quarter are due to a slowdown in
carrier spending on certain Ulticom related projects and the corresponding
customer shipments of Signalware enabled products," said Shawn Osborne,
President and CEO of Ulticom. "Although these factors have affected our
near-term results, we remain focused on leveraging our OEM relationships,
efficient operations, and strong balance sheet to expand our position enabling
wireless and broadband services."

The Company is scheduled to release its final first quarter results in the first
week of June 2005, and will host a conference call following the release to
discuss the quarter results and update financial guidance.

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 from forecasts and
estimates are: risks associated with weaknesses in certain sectors of the global
economy generally, and in certain sectors of the telecommunications industry in
particular; risks associated with our dependence on a limited number of
customers for a significant percentage of our revenues; risks associated with
rapid technological changes in the telecommunications industry; risks associated
with making significant investments in the expansion of our business and with
increased expenditures; risks associated with holding a large proportion of our
assets in cash equivalents and short-term investments and the reduction of
prevailing interest rates; risks associated with our products being dependent
upon their ability to operate on new hardware and operating systems of other
companies; risks associated with our dependence on sales of our Signalware
products; risks associated with future networks not utilizing signaling systems
and protocols which our products are designed to support; risks associated with
the development and acceptance of new products and product features; risks
associated with our products having long sales cycles and our limited ability to
forecast the timing and amount of product sales; risks associated with the
integration of our products with those of equipment manufacturers and
application developers and our ability to establish and maintain channel and
marketing relationships with leading equipment manufacturers and application
developers; risks associated with our reliance on a limited number of
independent manufacturers to manufacture boards for our products and on a
limited number of suppliers for our 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 our intellectual property rights and the inappropriate use by
others of our proprietary technology; risks associated with prevailing economic
conditions and financial trends in the public securities markets in general, and
in the decline in the stock prices of technology companies in particular,
including Ulticom; risks associated with the need for the Company to attract and
retain key personnel and 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. 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 reports on Form 10-Q. All
