VON Expo, BOSTON, and TEL AVIV (October 30, 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 major enhancements to its next generation SCOPIA platform , including SCOPIA MCU , SCOPIA Desktop and the iVIEW Suite , to provide a comprehensive and affordable solution for High Definition (HD) multipoint video conferencing. The new version 5.5 is a system release with significant enhancements across the product line.

SCOPIA V5.5 New Features and Functionality

The SCOPIA family of video conferencing and collaboration tools is a complete unified communications solution that delivers a very cost-effective, high quality video experience – anywhere and anytime. Enterprise users can enjoy easy-to-use video connectivity at all levels of the organization – from users at their desktops and on the road, to partners, colleagues and suppliers. The single solution ensures reliable interoperability between different systems and resolutions, such as 3G, standard definition (SD), high definition (HD) and desktops.

The SCOPIA Multipoint Conferencing Unit’s (MCU) High Definition capabilities now include HD Continuous Presence and the ability to mix HD and standard room systems and desktops in the same call without all participants downgrading to their common capabilities. With the SCOPIA platform’s optimized capacity, users receive maximum value for their investment based on the video application – for example, if HD is not fully utilized, the number of available ports for Standard Definition and Desktop increases for a reduced cost per port.

The new version of the innovative SCOPIA Desktop solution now leverages the enhanced HD capabilities of the SCOPIA MCU along with adding productivity enhancements, such as text chat, conference moderation, and waiting room capabilities. SCOPIA Desktop extends the capabilities of the SCOPIA MCU to remote users with a free, Web-based client, H.239 data collaboration, embedded firewall and NAT traversal and conference streaming.

SCOPIA’s iVIEW Suite management software, providing call distribution and routing, reporting, scheduling, network management, and groupware integration, has been enhanced to support the HD capabilities of the SCOPIA MCU. The iVIEW Suite now provides High Availability redundancy, meeting the need for mission critical HD conferencing in the enterprise.

The SCOPIA V5.5 portfolio is a complete Unified Visual Communications solution, including desktop, Standard Definition, and High Definition multipoint conferencing capabilities, gateway, gatekeeper, Web-based client, firewall traversal, streaming, and overall application management providing the best performance, pricing, and value available in the market today.

“Through SCOPIA and its SCOPIA Desktop offering, we can provide our constituents a completely seamless solution that allows desktop and remote users to connect to our existing video network infrastructure capable of High Definition conferences,” said Steve Cachia, Manager for Video Network Services, University of Houston-Downtown Division of Information Technology . “RADVISION’s advances with the SCOPIA platform once again demonstrate our shared vision of what video conferencing can do, and where it can and will take us.”

“Wainhouse Research is pleased to see RADVISION enhance its SCOPIA platform to support mixed mode conferences of High Definition, Standard Definition and desktop users,” said Ira Weinstein, Senior Analyst and Partner with Wainhouse Research. “The company’s unique method of processing High Definition on the SCOPIA MCU combines HD video quality and cost effectiveness, making it well suited for the mixed mode conferencing environments of today.”

“Our approach to High Definition conferencing with the SCOPIA MCU, SCOPIA Desktop, and iVIEW Suite represents RADVISION’s unique capabilities to provide value and benefits to our customers,” said Zeev Bikowsky, GM of RADVISION’s Enterprise Business Unit. “Today’s enterprises are steeped in the practical environments of differing systems, like Standard Definition, desktops, and High Definition room systems – all in the same conference. With these enhancements to the SCOPIA platform, we also bring the benefit of extending High Definition room conferencing to the desktop, which is truly extending the utility and reach of the new breed of HD room systems available.”

RADVISION will be exhibiting the SCOPIA V5.5 product lineup, including SCOPIA Desktop and High Definition (HD) Continuous Presence video conferencing, at the Fall 2007 VON Expo, October 30-31, Boston Convention and Exhibition Center, Boston, Massachusetts, booth 537.
