Groundbreaking Joint Venture by Market Leaders Generates Immediate Results

New Delhi, December 4, 2007 - Comverse, the world's leading supplier of software and systems enabling network-based multimedia enhanced communication and billing services, today announced live commercial implementation of the Fun Broker off-deck ringback tone platform at T-Mobile Germany, a unit of Deutsche Telekom (NYSE: DT) together with Jamba, a leading provider of digital entertainment services through a joint venture between News Corporation (NYSE: NWS) and VeriSign (NASDAQ: VRSN). Now available globally, Fun Broker allows content providers to sell ringback tones directly from their portals. Integrating ringback tones into the dynamic off-deck content retail market helps subscribers to personalize ringback tones easily from multiple media sources, which can increase penetration of the service.

Fun Dial, Comverse's popular ringback tone service, allows users to personalize network tones (ringing, busy signals) with music and content to entertain callers waiting for the phone call to be answered. The entry of leading content players like Jamba into the ringback tone service arena increases user awareness, convenience and choice, which can generate substantial new traffic and revenue in ringback tone content.

Lee Fenton, COO at Jamba said, "Operators have too much to do already to successfully take on the entire burden of constant promotion of ringback tones. By turning to Jamba and value-added services leader Comverse, T-Mobile gains energetic and motivated market-savvy content and service delivery partners and benefits from our highly popular portal for digital entertainment. It is no surprise that ringback tone sales and usage figures quickly shot up. We believe that their long-term gains will be equally impressive."

"Comverse creates great customer experiences and Fun Dial has become the best-in-class ringback tone experience. Now with Fun Broker, we can bring content from the best worldwide sources like Jamba. Jamba plus Comverse is a world's best customer experience," said Andre Dahan, President and CEO of Comverse.
