RADVISION Continues Market Leading Enhancements to Desktop
Platform as Adoption Accelerates

Monday October 20, 9:00 am ET

RADVISION Showcases SCOPIA Desktop with Improved High Definition Technology
Delivering an End-to-End High Definition Video and Data Experience

PARIS & 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 that it will demonstrate its
latest high definition (HD) desktop video conferencing advancements, including
HD motion video and HD data sharing, on October 21st - 23rd at the IP
Convergence Expo in Paris.

Building on the award-winning SCOPIA Desktop's HD 720p receive capabilities
currently available, SCOPIA Desktop users will now be able to send HD business
quality video from a PC with a standard consumer USB web camera. This will allow
all conference participants on desktops or room systems to see desktop
participants in full HD, significantly improving the conference experience
especially in full screen mode. This capability is being demonstrated using a
widely available and affordable Logitech(R) QuickCam(R) Pro 9000 USB camera with
RADVISION's SCOPIA Desktop software on a standard PC delivering an exceptional
value for a full HD desktop solution.

RADVISION is also furthering its lead in the desktop arena with the
implementation of HD data sharing. Using H.264 HD codec technology for the H.239
data channel in SCOPIA Desktop, data sharing is now at HD crystal clarity. Data
collaboration via the H.239 standard is a key component to effective meetings
between room systems and desktop video conferencing. Now, with the addition of
high definition support, it provides a true end-to-end HD experience for both
video and data. It also delivers better bandwidth utilization resulting in
improved image quality and lower delay even in low bandwidth environments.

SCOPIA Desktop extends room system based video conferencing deployments by
allowing remote users to connect to conferences and fully participate in audio,
video, and data collaboration as if they were in the same room. SCOPIA Desktop's
unique market leading features include a freely distributable web client,
automatic firewall traversal, voice-video-data interoperability and end-to-end
high definition. SCOPIA Desktop can be used by anyone inside or outside the
enterprise firewall making it easy to connect to and 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.

These unique capabilities continue to drive wide-scale market acceptance and
adoption of SCOPIA Desktop, introduced in June 2007. Port licenses for SCOPIA
Desktop, which is bundled with the SCOPIA platform, are free but must be
requested by users. The number of port licenses for SCOPIA Desktop more than
doubled in the first six months of 2008 compared with the last half of 2007.
Now, with over 15,000 ports deployed, these shared ports are in use in
enterprises, governments, educational institutions and other organizations
worldwide supporting tens of thousands of users. RADVISION's continued
investment in SCOPIA Desktop including these latest enhancements is improving
the quality and experience of desktop conferencing and accelerating the
extension of video conferencing to the desktop.

"As the market moves to high definition, users are expecting the same HD quality
across any device they choose to participate with in the conference - not just
for video, but also for presentations and other materials," said Boaz Raviv, CEO
of RADVISION. "The high definition capabilities that SCOPIA Desktop now offers
utilizing affordable off-the-shelf cameras and PCs are second to none in the
market."

"In May of this year, we awarded RADVISION the 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, advanced network management capabilities,
but largely due to the integration of desktop conferencing," said Krithi Rao
Industry Analyst - Unified Communications for Frost & Sullivan. "RADVISION
continues to pace the market delivering what users want and their success in the
market with SCOPIA Desktop shows it."

RADVISION will be exhibiting SCOPIA Desktop with this latest high definition
(HD) capability and unified communications integration with IBM and Microsoft
solutions at the IP Convergence Expo in Paris, October 21 - 23, Porte De
Versailles, stand D12.
