RADVISION Announces Market Leading Quality Improvements and Enhanced Scalability to Award Winning SCOPIA Desktop Platform

SCOPIA Desktop V7.0 Delivers H.264 Scalable Video Coding (SVC), High Definition
(HD) Recording and Playback and Enhanced Point-to-Point Calling

TEL AVIV, Israel--(Business Wire)--
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 significant updates
to the SCOPIA Desktop platform that serve to continue to enhance and deliver an
unequalled desktop video conferencing experience.

SCOPIA Desktop is the award winning desktop video platform that makes it easy to
extend video conferences to remote users and allows them to fully participate in
meetings no matter where users are: at their desk, at a customer location, or in
a hotel in another part of the world. This innovative Web-based desktop
conferencing solution allows users to share full voice, video and data, with
traditional room systems, telepresence systems, mobile devices and desktops all
in one conference and can be used by anyone inside or outside the enterprise
firewall.

RADVISION is further enhancing this solution with advanced H.264 Scalable Video
Coding (SVC) technology. Maintaining high quality calls with participants over
unmanaged networks like the public Internet can be problematic because of packet
loss and limited bandwidth. SCOPIA Desktop V7.0 with H.264 SVC scalable video
coding technology provides very high error resiliency while maintaining
interoperability with current room video conferencing systems. RADVISION`s SVC
implementation is an extension to the H.264 video standard used by most video
conferencing devices today. SCOPIA Desktop users will now receive a high quality
experience even in impaired network conditions. H.264 SVC along with integrated
firewall and NAT traversal capabilities ensures that network impediments do not
interfere with having a good conferencing experience.

SCOPIA Desktop V7.0 will also bring point to point calling through a presence
enabled contact list providing the ability to call another desktop user directly
without utilizing SCOPIA MCU resources. This new capability provides enhanced
scalability supporting thousands of simultaneous calls on a single system.
SCOPIA Desktop`s new presence enabled contact list offers fast and simple
conference initiation to other SCOPIA users or video conferencing room systems.
The presence enabled contact list also delivers seamless transition from point
to point to multiparty calls. In addition, SCOPIA Desktop`s integrated firewall
and NAT traversal capability has been enhanced to support the new point to point
feature.

SCOPIA Desktop`s recording facility has been further enhanced to record video
conferences in HD. Users can access a recorded meeting and watch the playback as
a media file in full HD. These media files can also be saved and viewed locally
on a user`s PC or MAC allowing the user complete flexibility of when and where
to view the recording without having to be connected to the network. They can
also be converted and played back on mobile devices such as an Apple® iPhone™ or
iPod®.

Additional SCOPIA Desktop V7.0 enhancements include:

* Automatic CPU awareness supporting netbook to quad processor systems
guaranteeing the best quality experience available on each PC processor class.
* Administrator controls to grant different privileges for system guests and
authenticated users.
* Per user bandwidth controls allowing administrators to restrict bandwidth of
an individual user in addition to a per conference basis.

"SCOPIA Desktop V7.0 brings significant new features and further extends our
leadership in the desktop market," said Boaz Raviv, CEO of RADVISION. "As the
desktop market expands, these new features will ensure that our customers can
scale their deployments over their existing networks while still maintaining
excellent quality video. With these additions we envision adoption of desktop
video to accelerate and become a very important part of every enterprise`s
communication strategy."

The Korea Cadastral Survey Corporation (KCSC), Korea`s national surveying
agency, recently upgraded their conferencing application to RADVISION`s
solution. "This upgrade of the conference system to RADVISION has enabled not
only high definition room to room video conferencing, but also direct video
communications for all employees, saving us time and travel cost," said Mr. Chul
Soon Song, CIO of KCSC. "This upgrade of video communications will be a
foundation to our corporation`s target for "Green Growth and Increased Business
Efficiency."
