Comverse Technology, Inc. (NASDAQ: CMVT) today announced that Comverse Inc. has
signed a definitive agreement to acquire privately-held Netcentrex S.A., for
approximately $164 million in cash, subject to certain adjustments and a
contingent earnout of up to an additional $16 million. The actual amount of the
contingent earnout payment, if any, will be determined based upon achievement of
certain financial targets by the Netcentrex business during the remainder of
fiscal 2006 and for fiscal 2007.

The combination of Netcentrex, a leader in network-based software enabling
IP-based voice-video-data ("triple-play") and FMC (fixed-mobile convergence)
solutions for service providers, serving the enterprise and consumer segments,
with Comverse's portfolio of value-added multimedia messaging, content and
converged billing solutions, is expected to benefit operators deploying
differentiating, multimedia services in the VoIP (Voice-over-Internet Protocol)
and IMS (IP Multimedia Subsystem) domains. The acquisition, which is expected to
close by July 1, 2006, is projected to be neutral to the company's fiscal 2006
(year ending January 31, 2007) pro forma net income. Pro forma net income
excludes the impact of purchase accounting adjustments related to the write-down
of deferred revenue, amortization of intangibles, and other acquisition-related
costs, among other items.

Kobi Alexander, Chairman and CEO of Comverse Technology, said, "We believe VoIP,
FMC and IMS-based communication services are poised to grow in the coming years,
and that Netcentrex is well-positioned to address many of these opportunities.
Together, the two companies offer a broad portfolio that enables converged
voice-video-data solutions, serving wireless, fixed, cable, MVNO and
Internet-based communication service providers."

Zeev Bregman, CEO of Comverse, the company's network systems unit, said,
"Netcentrex complements our product portfolio, technology, and strategic
direction. Netcentrex's leading telco-grade application server, rich IP Centrex,
Class 5 and video services and proven market position (with over 2.8M live VoIP
lines), together with Comverse's telecom VAS and billing leadership, create a
synergetic, unique VoIP, FMC and IMS offering."

"We are delighted to join forces with Comverse," said Olivier Hersent, Chairman
and CTO of Netcentrex. "Our combined expertise will benefit both existing and
new clients, and will allow all types of operators to build innovative service
bundles based on IP applications."

Netcentrex brings to Comverse a broad suite of software-based converged
voice-video-data-over-IP solutions, supporting the consumer and enterprise
offerings of approximately 50 service providers, including AOL Germany,
Comunitel (Tele2), Fastweb, France Telecom, Telefonica Deutschland GmbH and
Tiscali.


For the year ended December 31, 2005, Paris-based Netcentrex generated revenues
of approximately $50 million.

The acquisition is subject to a number of closing conditions, including
approvals or expiration of waiting periods with respect to filings required by
competition laws or regulations, receipt of certain third party consents, the
tender of substantially all of Netcentrex shares by their holders at closing and
other customary conditions.
