TEL AVIV (January 29, 2008) –

RADVISION® Ltd. (Nasdaq: RVSN), a leading provider of video network infrastructure and developer tools for unified visual communications over IP, 3G, and emerging next-generation IMS networks, today announced that the company and its products have received a series of awards from leading industry analyst Videoconferencing (VC) Insight.

RADVISION was chosen as VC Insight’s “Unified Visual Communications Company of the Year 2007”. In the award selection, VC Insight took the user’s perspective and looked for innovation, reliability, ease of use, and price-performance.

RADVISION made significant advances in its product line in 2007, including the introduction of SCOPIA V5.5 with support for advanced high definition capabilities and optimized capacity as well as SCOPIA Desktop, resulting in an award-winning portfolio. In describing RADVISION, VC Insight noted, “RADVISION specializes in video conferencing infrastructure products. That is why Cisco OEMs some RADVISION products and why Sony and Aethra dealers offer RADVISION SCOPIA products with their excellent SD and HD endpoints. LifeSize infrastructure products also reflect a tie in with RADVISION. That confirms SCOPIA are the best infrastructure products available.”

The SCOPIA Desktop Video Conferencing client was also chosen as one of “The 10 Best New Video Conferencing Endpoints of the Year 2007”. RADVISION’s SCOPIA Desktop is a software based video conferencing endpoint which offers an extension of the SCOPIA conferencing platform. SCOPIA Desktop extends video conferencing deployments based in meeting-rooms allowing remote users to connect to conferences and fully participate in audio, video, and data collaboration. SCOPIA Desktop is a Web-based plug-in client that can be used by anyone inside or outside the enterprise firewall. As stated by VC Insight, “There is no simpler way to include many sites in distant locations in a conference between two or more room-based systems.”

VC Insight also recognized RADVISION’s SCOPIA V5.5 conferencing platform as one of “The Two Best New Video Network Infrastructure Products of the Year 2007”. The new SCOPIA V5.5 software is a system release with significant enhancements across the product line. It provides a comprehensive and affordable solution for High Definition (HD) multipoint video conferencing, including Continuous Presence and the ability to mix HD and Standard Definition (SD) video conferencing room systems and desktops in the same call without all participants downgrading to their common capabilities.

“RADVISION’s innovation and attention to customer needs has captured our attention again, and we have selected them as the Unified Visual Communications Company of the Year 2007 as we did for the Year 2006,” said Richard Line, Editor of VC Insight. “We like the high quality HD multipoint experience that the SCOPIA platform provides at an affordable price and the convenient way of connecting a remote or mobile worker to a video meeting.”

“RADVISION has made significant advances in its product line in 2007 addressing real customer issues in deploying unified visual communications. We invite all those deploying unified communications solutions to take a serious look at our offerings,” said Bob Romano, VP Enterprise Marketing for RADVISION. “We are pleased to be recognized across our solution portfolio by VC Insight.”
