RADVISION Enhances IBM Lotus Sametime with Multiparty Audio and
Video Using SCOPIA High Definition Conferencing Platform

Monday January 21, 8:00 am ET

RADVISION's SCOPIA Solution for IBM Lotus Sametime to be Demonstrated at
IBM Lotusphere

ORLANDO, Fla. & 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 its SCOPIA Conferencing
Platform will support IBM Lotus Sametime.

RADVISION's SCOPIA Conferencing Platform with SCOPIA Desktop will bring advanced
conferencing capability to IBM's next generation unified communications and
collaboration platform enhancing the instant messaging and conferencing
capabilities of Lotus Sametime by enabling users to create and initiate
multiparty audio and video conferences directly from within Lotus Sametime. By
adding RADVISION's unique video and audio plug-in to Lotus Sametime, users can
easily escalate Lotus Sametime instant messaging chat sessions into full
multiparty audio and video sessions on their PC and extend those conferences to
other devices such as room based video conferencing systems, 3G videophones or
virtually any telephone available today.

SCOPIA Conferencing Platform's high definition capabilities allow mixed
conferences of HD video systems, standard definition video systems and video
from desktops in the same call without requiring all participants to downgrade
to their common capabilities. Each user participates in the conference at the
highest capability available to them. SCOPIA provides the most affordable and
flexible platform in the market with support for HD, standard definition,
desktop, and 3G in a single solution with pricing and capacity optimized for
each conferencing application.

SCOPIA Desktop builds upon the technology of RADVISION's Click to Meet solution
for Lotus Sametime with the enhanced HD and high performance media processing
capabilities of the SCOPIA Conferencing Platform underneath. These new
capabilities provide a high quality conferencing experience even with limited
bandwidth applications when viewing multiple participants simultaneously within
Sametime.

"Integrating the advanced media processing capabilities of the SCOPIA
Conferencing Platform into Lotus Sametime brings another dimension of
conferencing to the Sametime unified communications environment," said Bob
Romano, Vice President Enterprise Marketing. "Now Sametime users can have mixed
conferences with virtually any type of device including the latest High
Definition products on the market without requiring any of those devices to
sacrifice quality."

RADVISION will be demonstrating the SCOPIA Conferencing Platform for Lotus
Sametime at the Lotusphere 2008 Product Showcase in Orlando - booth 302 opening
today.

Portfolio Recognized as Some of the Best New Video Conferencing Products of the
Year 2007

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 the company and its products have received a
series of awards from leading industry analyst Videoconferencing (VC) Insight.

RADVISION was chosen as VC Insight's "Unified Visual Communications Company of
the Year 2007." In the award selection, VC Insight took the user's perspective
and looked for innovation, reliability, ease of use, and price-performance.

RADVISION made significant advances in its product line in 2007, including the
introduction of SCOPIA V5.5 with support for advanced high definition
capabilities and optimized capacity as well as SCOPIA Desktop, resulting in an
award-winning portfolio. In describing RADVISION, VC Insight noted, "RADVISION
specializes in video conferencing infrastructure products. That is why Cisco
OEMs some RADVISION products and why Sony and Aethra dealers offer RADVISION
SCOPIA products with their excellent SD and HD endpoints. LifeSize
infrastructure products also reflect a tie in with RADVISION. That confirms
SCOPIA are the best infrastructure products available."

The SCOPIA Desktop Video Conferencing client was also chosen as one of "The 10
Best New Video Conferencing Endpoints of the Year 2007." RADVISION's SCOPIA
Desktop is a software based video conferencing endpoint which offers an
extension of the SCOPIA conferencing platform. SCOPIA Desktop extends video
conferencing deployments based in meeting-rooms allowing remote users to connect
to conferences and fully participate in audio, video, and data collaboration.
SCOPIA Desktop is a Web-based plug-in client that can be used by anyone inside
or outside the enterprise firewall. As stated by VC Insight, "There is no
simpler way to include many sites in distant locations in a conference between
two or more room-based systems."

VC Insight also recognized RADVISION's SCOPIA V5.5 conferencing platform as one
of "The Two Best New Video Network Infrastructure Products of the Year 2007."
The new SCOPIA V5.5 software is a system release with significant enhancements
across the product line. It provides a comprehensive and affordable solution for
High Definition (HD) multipoint video conferencing, including Continuous
Presence and the ability to mix HD and Standard Definition (SD) video
conferencing room systems and desktops in the same call without all participants
downgrading to their common capabilities.

"RADVISION's innovation and attention to customer needs has captured our
attention again, and we have selected them as the Unified Visual Communications
Company of the Year 2007 as we did for the Year 2006," said Richard Line, Editor
of VC Insight. "We like the high quality HD multipoint experience that the
SCOPIA platform provides at an affordable price and the convenient way of
connecting a remote or mobile worker to a video meeting."

"RADVISION has made significant advances in its product line in 2007 addressing
real customer issues in deploying unified visual communications. We invite all
those deploying unified communications solutions to take a serious look at our
offerings," said Bob Romano, VP Enterprise Marketing for RADVISION. "We are
pleased to be recognized across our solution portfolio by VC Insight."
