Leading provider of Video Conferencing technology that enables telecommuting to reduce carbon emissions advances environmental commitment through electronic availability of Annual Report

Tel Aviv (August 25, 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 networks, today announced that it has posted its annual report containing its audited consolidated financial statements for the year ended December 31, 2007 on its Web site (http://www.radvision.com/Corporate/Investors/SECFilings/). The Company’s annual report on Form 20-F was filed with the U.S. Securities and Exchange Commission on June 24, 2008 and is also available on the SEC Web site (http://www.sec.gov/ ). Shareholders may receive a hard copy of the annual report free of charge upon request.

In line with a recent change in NASDAQ regulations allowing companies to make their annual reports available electronically and avoid printing hard copies for each shareholder, RADVISION has opted to post the annual report on its Web site and continue its track record of being environmentally responsible. By doing so, the company will save thousands of pages of paper, thereby reducing costs while being environmentally conscious as well.

RADVISION is committed to reducing the environmental impact of daily business and, through its award winning SCOPIA Conferencing Platform, the company provides an effective telecommuting option to businesses and employees. Through video conferencing, businesses are able to reduce carbon emissions by reducing commuting and business travel time, which significantly lowers the company’s carbon footprint. Telecommuting via video conferencing also benefits businesses by:

*
Cutting back on the amount of energy used in daily operations
*
Better utilizing its workforce across the country and the world
*
Providing a better work/life balance for its employees, who can now spend time usually spent traveling with their families

“RADVISION recognizes that businesses need to operate with the highest levels of efficiency while also remaining eco-friendly and we’re proud to offer a technology that accomplishes both goals,” said Boaz Raviv, CEO of RADVISION. “Video conferencing is not the new frontier of communication in business, it is the new reality. By offering businesses a way to connect their employees across the world without ever leaving their homes or offices, RADVISION is able to provide a cost-effective, environmentally responsible method of global unified communications.”.

The latest release of RADVISION’s SCOPIA Conferencing Platform, Version 5.6, delivers High Definition HD video conferencing, multiparty audio and video to IBM Lotus Sametime, standards-based video conferencing connectivity to Microsoft Office Communicator 2007 and support for Cisco Unified Videoconferencing, powered by SCOPIA technology.

Earlier 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.
