Sogetel and Warwick Telephone Select Tekelec Distributed Switching Solution For VoIP; Canadian IOCs Will Leverage Superior Features, Functionalities and Value of Tekelec 9000 Distributed Switching Solution.

MORRISVILLE, N.C. -- Tekelec (NASDAQ: TKLC), a leading developer of high-performance network applications for next-generation fixed, mobile and packet networks, today announced that two Canadian independent operating companies (IOCs), Sogetel and Warwick Telephone (La Compagnie de Telephone de Warwick), are deploying the Tekelec 9000 Distributed Switching Solution to support their voice over Internet protocol (VoIP) and data services.

Based in Quebec, Canada, and servicing a combined 30,000 subscribers, each company will leverage the industry-unique architecture of the Tekelec 9000 to provide both native packet and time division multiplexing (TDM) services from a single platform. Additionally, the operators will have the ability to cap and grow costly existing legacy systems while offering enhanced IP services by deploying the Tekelec 9000 backbone network, which consists of multiple distributed Tekelec 8000 Wireless Multimedia Gateways and Tekelec 3000 Media Gateway Controllers.

"Tekelec 9000 uniquely addresses our most critical business drivers, including the ability to offer new revenue-generating services while reducing operating expenses," said Luc Couture, general director of Warwick Telephone. "We see it as the most reliable and feature-rich softswitch on the market."

Alain Duhaime, president of Sogetel, added, "Tekelec's distributed switching solution provides all the capabilities we need to cap and replace existing switching networks, along with a feature-rich platform for packet services and transport. The solution was a clear choice in a crowded market, and it allows Sogetel to enhance its position as a pace setter in Canada for providing new and advanced services."

Both Sogetel and Warwick Telephone are new Tekelec customers and chose the company after a 12-month review process. Sogetel is the largest IOC in Quebec.

"By deciding to deploy our next-generation switching solutions, Sogetel and Warwick Telephone have each purchased much more than a softswitch," said Jay Whitehurst, president and general manager, Tekelec Switching Solutions Group. "They have chosen a solution with unmatched quality, reliability, rich VoIP features and cost savings, - and they have recognized our ability to be a strong partner over the long term."
