NMS Communications' Vision Video Gateway Delivers Exciting 3G Video Applications to Drive ARPU; Spanish service provider Ydilo tests gateway for high-quality, low-latency mobile video application.

BOSTON -- At Fall VON, NMS Communications (NASDAQ: NMSS), a leading provider of communications technologies and solutions for converged and mobile networks, today announced the availability of the Vision Video Gateway, the latest member of the Vision family of communications platforms (www.nmscommunications.com/vision).

The Vision Video Gateway is designed to help mobile operators offer value-added, high margin, multimedia services such as video streaming, on-demand video streaming and video messaging including chat, mail and user-created videos. Research firm In-Stat projects by 2010 there will be 102 million mobile video subscribers worldwide, while Ovum predicts that the worldwide revenues for person-to-person video calls alone will reach $6.1 billion by 2009. The Vision Video Gateway enables mobile operators and their mobile video application developer partners to better succeed in the exploding video market by providing a scalable, cost-effective interface between 3G-324M and IP networks, letting mobile operators deploy high quality, real-time conversational video applications over a circuit-switched protocol, while deploying other services -- such as web-based applications -- over the IP network.

Spain-based multimedia solution provider Ydilo is enthusiastic about the performance of NMS's video gateway with a trial video push tutorial application. "Consumers expect mobile video applications to be high quality with very low latency. This is inherently complex to produce in heterogeneous networks," said Mark O. Loeches, marketing manager for Ydilo. "The technology provided in the Vision Video Gateway makes it possible for users of 3G mobile phones to experience the video they have become accustomed to on their TV screens, with very low lag time."

The Ydilo trial was facilitated through NMS's Spain-based distributor, Callware Voice Technologies. Callware is an established distributor in the telecom industry, specializing in open components, voice and data convergence networking solutions, IP telephony and computer-based telephony for both corporate markets and service providers. The relationship with Callware expands the reach of NMS's Vision family of communications platforms and Open Access platforms in this region.

"Several technologies must be interwoven to allow the connection of mobile and fixed IP video users. The Vision Video Gateway translates between video from mobile user and PC users on the fixed IP side to facilitate high quality, low-latency video calls," said John Orlando, chief marketing officer for NMS. "The Video Gateway is the latest member of the Vision family to allow service providers, OEMs and application developers to bring cutting-edge multimedia solutions to market faster than ever before."
