Syniverse Technologies and Preferred Voice to Offer Ringback Service to Mobile Operators

SAN FRANCISCO--(CCNMatthews - Sep 27, 2005) -

News Summary: Syniverse and Preferred Voice to co-market network-based ringback services to wireless carriers.

Syniverse Technologies (NYSE:SVR), a leading provider of mission-critical technology services to wireless telecommunications companies worldwide, announced today it has formed a sales and marketing alliance with Preferred Voice, Inc. (PVI) (OTCBB:PFVI), a leading provider of mobile personalization services, to offer ringback service to mobile operators.

Preferred Voice launched the first commercially available ringback service in the United States in late 2004. Ringbacks enable users to choose an audio file that callers listen to while the phone is ringing, replacing traditional rings. The service allows for personalization, particularly popular to the youth market.

"Our long-term, trusted relationships with all of the carriers in North America make us the logical partner for Preferred Voice to expand their reach. Their managed service approach and proven architecture is attractive to wireless carriers. Based on the rapid adoption of ringback service taking place in Asia, we are confident that this will be a beneficial partnership for both companies," said Michael O'Brien, vice president-marketing, Syniverse.

"Syniverse is a highly regarded provider of network services and the quality and quantity of their business and technical relationships with carriers in North America is unmatched," said Ron Maness, senior vice president - platform sales, Preferred Voice. "Based on our initial launches, we know that many carriers in second and third tier markets are looking for revenue-producing opportunities that are competitive with larger carriers. Since ringback service is based on the wildly popular concept of personalization and mobile music, we believe our service, combined with Syniverse's customer support and co-marketing could be one of the fastest growing mobile services this year."
