'Clientless' Visual Voicemail Helps Subscribers Hear Messages
              Faster, Works on Virtually All Handsets

Comverse Visual Voicemail has been deployed by TMN, Portugal's largest
mobile operator, to enable users to hear voice messages as soon as they
are recorded -- without requiring specific handsets.

To ensure mass-market availability, TMN Portugal selected a
"clientless" form of Comverse Visual Voicemail, which notifies
subscribers with a multimedia message (MMS) about the caller's identity
and message length and time. Subscribers then click to listen, and the
message also can be easily stored and forwarded.

"By infusing voice messaging with unbeatable speed and ease of use,
Voicemail-to-MMS makes voicemail highly attractive to our users," said
Mário Sousa, Head of Data and Content at TMN. "Comverse's
clientless Visual Voicemail solution enables us to extend the service
to the broadest number of consumers. As we expected, there is positive
impact on the number of messages deposited, message retrievals, calls
returned and overall user satisfaction. The Voicemail-to-MMS service is
clearly answering our ultimate goal of increasing voicemail usage."

The global market leader, Comverse has more than two-thirds of visual
voicemail commercial deployments worldwide.

"Clientless deployment puts Visual Voicemail where it should be -- into
the hands of as many users as possible -- as fast as possible," said
Dror Bin, President of Global Sales at Comverse, the world's leading
supplier of software and systems enabling value-added messaging and
content services, converged billing and active customer management, and
IP communications.

"Results from TMN support the principle that when callers know message
delivery is instantaneous, they deposit more voice messages. Similarly,
the relevance of immediate listening stimulates people to return more
calls," Bin said. "The bottom line is greater user satisfaction and
higher voicemail usage, which operators report can increase as much as
30 to 50 percent. Moreover, adding multimedia capabilities to voicemail
paves the way for several attractive revenue generating opportunities
and services, such as branding and mobile advertising."
