MORRISVILLE, N.C. -- Tekelec (NASDAQ: TKLC), a leading developer of high-performance network applications for next-generation fixed, mobile and packet networks, announced today that Technology Marketing Corporation's (TMC[R]) INTERNET TELEPHONY[R] Magazine has named Tekelec's 7000 Enhanced VoIP Solution (EVS) as recipient of its 2006 Product of the Year Award.

The Tekelec 7000 EVS combines the Tekelec 7000 Integrated Switching Solution and the Tekelec 6000 VoIP Application Server, creating a system that carriers can deploy in single or distributed locations. The solution enables carriers to quickly roll out IP-enabled service offerings to residential and business customers, and it supports both time division multiplexing (TDM) and next-generation interfaces. These interfaces include IMS-Ready session initiation protocol (SIP), media gateway control protocol (MGCP) and Skinny Client Control Protocol (SCCP). Its flexibility allows carriers to extend investments in legacy networks as they migrate to a converged voice, broadband data, video and wireless network model.

"Tekelec provides innovative, next-generation products and real-world solutions that allow operators to migrate to IMS-based architectures and offer the most advanced services while reducing costs," said Jay Whitehurst, president and general manager, Tekelec Switching Solutions Group.
