SCOPIA Desktop Extending Room System Video Conferences to Any Remote User with a PC and an Internet Connection to be Showcased at InfoComm 07

ANAHEIM, InfoComm and TEL AVIV (June 18, 2007) –

RADVISION (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 the general availability of its SCOPIA Desktop video conferencing solution – an important extension of the SCOPIA unified communications platform.

SCOPIA Desktop extends room system based video conferencing deployments by allowing remote users to connect to conferences and fully participate in audio, video, and data collaboration as if they were in the same room. SCOPIA Desktop uses a freely distributable Web-based plug-in that can be used by anyone inside or outside the enterprise firewall. SCOPIA Desktop makes it easy to connect to and fully participate in meetings no matter where users are – at their desk, at a customer location, or in a hotel in another part of the world; further extending one of the SCOPIA platform’s missions to easily connect any communications device anywhere.

Traditional video conferencing users have benefited from the value of voice, video and data collaboration between conference rooms, but there has been no simple way to include users at their desktops or remote users on laptops that did not involve complex software installations, expensive licensing fees or firewall traversal problems. SCOPIA Desktop eliminates these issues.

SCOPIA Desktop Highlights:

* Delivers a high quality interactive video collaboration experience from a PC
* Provides face-to-face communication to conferencing room systems that is as easy as Web conferencing
* Accessed through a freely distributed browser plug-in so anyone, anywhere can participate in a conference
* Includes automatic and transparent firewall traversal for users outside the enterprise network
* Offers the same experience for all participants, whether connected from a conference room or a PC
* Enables data collaboration interoperability via H.239 with room systems
* Provides conference broadcasting via streaming to large audiences, including both PC and Mac users
* Is centrally managed and deployed for remote users eliminating IT administration headaches

RADVISION will be exhibiting a broad range of advanced video solutions including SCOPIA Desktop and High Definition (HD) video conferencing capability at InfoComm 07, June 19-21, Anaheim Convention Center, Anaheim, California, booth 4643 in the Collaborative Conferencing Pavilion.

SCOPIA Desktop has gone through extensive testing with hundreds of live conferences involving many locations, customers and partners. Meeting participants have successfully connected with SCOPIA Desktop’s Web-based client from a full range of locations regardless of their firewall configurations. The initial reaction to the product has been very positive from customers and partners.

“SCOPIA Desktop has made it possible to extend our room system deployment to users at their PCs in a way that has not been possible with any other solution in the market until now,” said Oscar Monrio de la Herran, IT Manager of Banco Espírito Santo S.A., Sucursal en España. “RADVISION’s solution delivers what is really needed for desktop conferencing with their Web-based client, transparent firewall traversal, and interoperable data sharing between room conferencing and desktops. Now we can allow users to participate in group conferences no matter where they are and we are seeing significant productivity gains from this capability.”

Boaz Raviv, RADVISION’s CEO said, “We are excited to deliver SCOPIA Desktop to the market. Our customers have been telling us that they want a simple way to connect their room conferencing installations to desktop and remote users and we are delivering that capability today. We are pleased to bundle this capability into our award winning SCOPIA platform, further enhancing the value of the SCOPIA family to our customers.”
