RADVISIONâ??s SCOPIA Conferencing Platform, Winner of the 2008 Frost & Sullivan Award for Product Differentiation Innovation, Further Sets Itself Apart In Meeting the Evolving Needs of the Unified Communications Market

LAS VEGAS InfoComm and TEL AVIV (June 18, 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 major advancements to its award winning SCOPIA Conferencing Platform. Available as a software upgrade to existing SCOPIA deployments, Version 5.6 delivers significant enhancements across the entire SCOPIA platform including the SCOPIA MCU, SCOPIA Desktop, and the iVIEW Management Suite. Enhancements include features for enhanced video quality including desktop HD video, ease of use and integration into the IBM Lotus unified communications platform.

High Definition (HD) Desktop Video
Version 5.6 introduces High Definition video conferencing to the desktop via the SCOPIA Desktop browser-based plug-in. Now desktop users can receive and view a full 16:9 widescreen HD 720p image right at their desktop significantly enhancing the user experience. SCOPIA Desktop users can now receive 720p images while sending 480p or CIF images preserving bandwidth and processing power. Receiving a very high quality HD image provides a striking improvement over the standard resolution video quality most other desktop systems offer.

Conference Recording and Content Management
As video is more widely used through unified communications product offerings, users have increased their requirements from not only interactive and streaming capabilities but to also be able to record, archive, and view their meetings, classes or training sessions. Version 5.6 enhances the existing streaming capabilities of the SCOPIA platform with the introduction of recording, playback and content management. This new capability includes recording of the audio, video and H.239 data collaboration. Recorded content can be easily organized and managed providing for simple user access and time-shifted playback and review on a standard PC. Access can be controlled by enterprise directory credentials for security of the content.

SCOPIA at the Core of Video Enabled Unified Communications Solutions
RADVISION’s SCOPIA Version 5.6 continues its leading position at the core of video enabled unified communications with enhanced integration into IBM Lotus Sametime. The SCOPIA platform currently provides multiparty audio and video support for IBM Lotus Sametime, standards-based video conferencing connectivity for Microsoft Office Communicator 2007; and support for Cisco Unified Videoconferencing powered by SCOPIA technology. V5.6 enhances the SCOPIA solution to provide support for Domino directory and Notes scheduling; providing easier management and access through IBM Lotus Sametime.

Additional SCOPIA Version 5.6 Enhancements Include:

* A system-wide video IVR allowing simple creation and selection of video conferences through a video conferencing room system including when conferences span multiple MCUs.
* Data collaboration with annotation for SCOPIA Desktop including H.239 compatibility allowing annotations to be visible on H.239 equipped room systems.

In May of this year, RADVISION was presented with the prestigious 2008 North American Frost & Sullivan Award for Product Differentiation Innovation for the SCOPIA Conferencing Platform. This was in recognition of market leading support for standard and high definition video, integration of desktop conferencing and advanced network management. The enhancements in V5.6 further extend the capabilities of the SCOPIA platform to provide an innovative and differentiated video conferencing solutions.

“RADVISION continues to listen and respond to customer requirements with features that meet the evolving visual requirements of the unified communication market,” said Krithi Rao Industry Analyst – Unified Communications for Frost & Sullivan. “Version 5.6’s delivery of desktop HD, recording and further integration with unified communication platforms, delivers the differentiation and innovation we have come to expect from the SCOPIA unified communications platform.”

“The enterprise market is changing rapidly with globalization of customers and suppliers, a more dispersed workforce and increased cost of travel. There has never been more of a need for simple cost effective conferencing and collaboration,” said Boaz Raviv, CEO of RADVISION. “We are providing our customers with solutions that make video conferencing simple by integrating into the market leading unified communication applications and a better experience by providing high definition to the desktop users.”
