FRAMINGHAM, Mass.--(BUSINESS WIRE)--Nov. 17, 2003

TeleSynergy has a long history as a supplier of IP-enabled enterprise communications solutions to some of the world's largest companies. As the range and sophistication of applications provided by TeleSynergy grew, so did the demands placed on its TeleCC7 switching platform, which provides call control and support for intelligent networking (IN) applications between the enterprise and the public network. To assure the flexibility and reliability essential for next-generation enhanced services such as unified communications, VoIP conferencing, short message service (SMS) and mobility, TeleSynergy turned to NMS Communications (Nasdaq:NMSS).

NMS has provided SS7 hardware and software building blocks for some of the most ambitious voice and data services in both wireline and wireless networks (www.nmscommunications.com/solutions/ss7). Based on that record, TeleSynergy switched to NMS for the foundation of its TeleCC7 gateway.

"We're confident that NMS is the right partner for us," said James Kou, COO of TeleSynergy. "NMS matched TeleSynergy's reputation for expertise in enterprise communications and for a complete line of highly reliable offerings, with equally reliable underlying hardware and software along with telecom and SS7 expertise."

According to a recent study by InfoTech cited in Internet Telephony Magazine, in the U.S. alone, over 40% of companies with more than 500 employees are converting their corporate phone system from the traditional PBX model to IP-based LAN technology. Additionally, the Gartner Group estimates that, driven in part by the growth in IP-enabled enterprise applications, by 2005, IP-based signaling solutions such as the TeleCC7 platform built on NMS technology will account for 41.9% of the Intelligent Network market or US$2.4 billion.
