RADVISION(R) Launches Version 5.1 of the SCOPIA(TM) Conferencing Platform

Wednesday January 10, 7:00 am ET

SCOPIA v.5.1 Introduces Flat Capacity PLUS(TM), Ensuring Conferencing Users More
Port Capacity at a Lower Cost per Port and the Latest Version of High Definition
Support

FAIR LAWN, N.J.--(BUSINESS WIRE)--RADVISION (NASDAQ: RVSN - News), a
leading provider of video network infrastructure and developer tools for unified
visual communications over IP, 3G, and emerging next-generation networks, today
unveiled version 5.1 of its SCOPIA platform which increases port capacity by 50
to 100 percent over the previous version and provides the latest support for
high definition (HD) video and audio conferencing.

With this release, RADVISION is introducing Flat Capacity PLUS(TM), a new
feature that ensures users receive maximum value for their investment. RADVISION
previously announced the SCOPIA platform with Flat Capacity support allowing
users consistent port capacity independent of video quality or network speeds
used. With Flat Capacity PLUS(TM), users now gain unmatched flexibility to
utilize capacity when using different levels of video and audio network speeds.
If all the available bandwidth is not fully utilized, the number of available
ports increases providing a reduced cost per port. This new feature adds
powerful flexibility, and makes RADVISION's SCOPIA platform an even more
cost-effective choice.

Also with this release RADVISION is making available the latest version of HD
support, providing customers with the best video and audio quality available
today without capacity loss and which is expected to be fully compatible with
all major HD endpoint manufacturers.

"The release of SCOPIA v.5.1 reflects our continued commitment to offering the
industry's most powerful, robust platforms for unified communications," said
Yoav Nativ, Product Marketing Manager, RADVISION. "Our development of Flat
Capacity PLUS and high definition support are a direct response to the market's
needs. These unique features address specific optimization issues inherent in
the diverse nature of videoconferencing, where not all sessions are the same.
With Flat Capacity PLUS, users can leverage all the power of the MCU according
to the right-sized configuration and capacity. With this release, we have
strengthened our position as the premier provider of multiparty conferencing
infrastructure for workflow and collaboration environments."

"RADVISION's commitment when launching the SCOPIA platform last year was to
provide the most powerful, flexible and affordable platform in the market and
continually improve it based on our customers needs," said Bob Romano, RADVISION
Vice President, Enterprise Marketing. "This release of SCOPIA continues to
deliver on that commitment. Flat Capacity PLUS provides users added value by
making available more ports if all calls aren't utilizing high bandwidth. In
addition, SCOPIA's support of HD allows customers to have multipoint
videoconferences on the latest generation of high definition video conferencing
devices. Users can now choose a single platform that will support high bandwidth
HD calls, normal bandwidth standard definition calls as well as receive extra
capacity for calls at lower bandwidth. That's flexibility,"
