                 CATAPULT COMMUNICATIONS REPORTS RECORD REVENUES
                       AND NET INCOME FOR FISCAL YEAR 2004

MOUNTAIN VIEW, CALIFORNIA OCTOBER 28, 2004 - Catapult Communications Corporation
(Nasdaq: CATT) today reported record revenues of $58 million for the fiscal year
ended September 30, 2004, an increase of 28% over fiscal 2003. Net income for
the fiscal year ended September 30, 2004 was a record $13.9 million or $0.95 per
diluted share. This compares to net income of $4.4 million or $0.33 per diluted
share for fiscal year 2003.

For the fourth quarter ended September 30, 2004, revenues were $15.4 million, an
increase of 51% over the fourth quarter of fiscal 2003. Net income for the
fourth fiscal quarter was $5.5 million or $0.38 per diluted share. This compares
to net income of $1.2 million or $0.09 per diluted share in the same quarter the
previous year.

Catapult recorded a tax benefit of $1.8 million or $0.12 per diluted share in
the fourth quarter of fiscal 2004. This reflects primarily a reduction in
accrued tax liability upon the successful completion of an IRS audit. In the
fourth quarter of fiscal 2003, a tax benefit of $1.7 million or $0.13 per
diluted share was recorded, reflecting the net impact of losses incurred in the
U.S. and profits generated in other jurisdictions, as well as an additional $1.5
million in tax benefits from the favorable resolution of international tax
issues.

"In the fourth quarter, our results once again exceeded our expectations, due to
stronger than anticipated performance in three of our four regions," said Dr.
Richard A. Karp, Catapult's Chairman and CEO. "Revenues in Europe were up 248%
year-over-year. In Japan, the rate of technological change - the primary driver
for our business - continues to be high. In our Rest of World region, which
includes China, where we recently opened an office, revenues were up 184%.
Although it will take time to build a strong presence in China, I continue to
view this as a high potential area."

During the fourth quarter of fiscal 2004, Catapult completed a stock offering
that included 200,000 primary shares. The offering also included 1,081,250
secondary shares which Tekelec received upon conversion of $17.3 million in
notes payable which had been issued as part of the purchase price for Catapult's
acquisition of Tekelec's network diagnostic business in 2002. The offering also
included 437,187 secondary shares sold by Dr. Karp and by Nancy Karp, a director
of Catapult, of which 137,187 shares represented an over-allotment option
exercised by the underwriters shortly after quarter end.

Catapult's combined cash and short-term investment position increased by $6.2
million to $52.7 million in the fourth quarter of 2004. Net proceeds from the
offering accounted for $3.0 million of this increase. With the conversion of the
notes payable, Catapult is once again debt-free.


BUSINESS OUTLOOK
"The current uncertainty in our North American region appears to be offset by
the exceptional growth in our other worldwide regions," stated Karp. "As a
result, I currently forecast that revenues in the first quarter of fiscal year
2005 will be $15.2 million, a 38% increase from the same quarter of our last
fiscal year, and that our diluted earnings per share will be 23 cents, a 229%
improvement from the same quarter a year ago."
