RADVISION Enhances the SCOPIA Conferencing Platform with High Definition Desktop
Video, Conference Recording, and Enhanced Integration into IBM Lotus Software

Wednesday June 18, 8:00 am ET

RADVISION'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 & TEL AVIV, Israel--(BUSINESS WIRE)--RADVISION(R) Ltd. (Nasdaq: RVSN -
News), 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:

     o    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.

     o    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
solution.

"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."

RADVISION will be exhibiting SCOPIA V5.6, including High Definition (HD) SCOPIA
Desktop, conference recording, and unified communications integration with IBM
and Microsoft solutions at the InfoComm Exhibition in Las Vegas, June 18 - 20,
Las Vegas Convention Center, booth C3387.
