RADVISION Delivers Room System Video Conferencing Connectivity to
Microsoft's Unified Communications Solution

Tuesday February 26, 9:00 am ET

New Application for Award Winning SCOPIA Conferencing Platform Provides Advanced
Video Conferencing System Interoperability to Microsoft Office Communications
Server (OCS) 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 the availability of a significant
enhancement to the SCOPIA(R) Conferencing Platform extending Microsoft(R) Office
Communications Server capabilities - the new SCOPIA Microsoft OCS 2007
Connector.

RADVISION, a Microsoft Gold Certified Partner, has been a long-established
partner with a history of support of Microsoft Real-Time Communications and
Unified Communications solutions including Microsoft Live Communications Server
2003 and 2005, Outlook, and Active Directory. With the recent introduction of
Microsoft Office Communications Server 2007, RADVISION is extending its support
of the Microsoft Unified Communications product line with the new SCOPIA
Microsoft OCS 2007 Connector.

The new SCOPIA OCS 2007 Connector enhances the Microsoft solution providing the
capability for Office Communicator users to participate in conferences with
standards-based video conferencing systems and devices. The SCOPIA Connector is
a simple-to-use, highly flexible tool allowing OCS 2007 users to join a meeting
hosted on the SCOPIA Conferencing Platform.

SCOPIA Conferencing Platform's media processing 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.

Benefits of the SCOPIA OCS 2007 Connector include:

     o    A simple  method for Office  Communicator  users to join SCOPIA hosted
          multi-party meetings.

     o    Conference  moderation  allowing Office  Communicator users to invite,
          disconnect,   and  mute  participants  along  with  controlling  other
          important aspects of the meeting.

     o    Support for HD (High  Definition)  providing  interoperability  to the
          latest video conferencing room systems available.

     o    Connectivity to H.323,  SIP, ISDN, and 3G video  conferencing  systems
          providing support for existing and future conferencing investments.

     o    Full transcoding and media processing  between various audio and video
          formats from 3G to HD video  allowing each  participant to utilize the
          highest quality available to them.

     o    A highly  collaborative  video  experience  where  through  Continuous
          Presence, multiple participants can be seen simultaneously.

     o    Efficient  bandwidth  utilization  where the  connection  rate remains
          constant regardless of the number of participants viewed.







The SCOPIA Connector is available immediately and is included at no additional
cost with SCOPIA 100 and 400 Conferencing Solutions.

"Extending the Microsoft Unified Communications solution with the advanced media
processing capabilities of the SCOPIA Conferencing Platform provides
connectivity that has been requested by many of our customers," said Zeev
Bikowsky, General Manager Networking Business Unit for RADVISION. "Now Office
Communicator users can have mixed conferences with nearly any type of device
including the latest High Definition room systems available."
