RADVISION and Clique Deliver End-to-End Video Solution

Monday October 29, 7:00 am ET

Joint marketing and development efforts will bring new interactive mobile video
telephony client application to market

* See live demo at VON Fall 2007 in Boston

TEL AVIV, Israel--(BUSINESS WIRE)--RADVISION (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 today that it has joined forces with Clique Communications,
Inc., a leading provider of IP video communication solutions, to jointly develop
a new video telephony client application for mobile devices. The mobile video
client application, focused on delivering superior video quality and an enhanced
user experience, is being developed using RADVISION's Multimedia Terminal
Framework.

By bundling RADVISION's SCOPIA Interactive Video Platform with the new Mobile
Video Telephony (MVT) application, RADVISION is uniquely poised to deliver an
end-to-end solution to mobile operators who want to drive revenue-generating
interactive video services, such as video communities and conferencing,
participation TV, Mobile surveillance and monitoring, video contact centers and
more.

"Our partnership with RADVISION is an important component of our mobile
strategy," said John Vitale, Director of Business Development and Strategic
Partnerships for Clique Communications. "The new MVT client will be compatible
with the nearly endless range of services that can be developed using the SCOPIA
Interactive Video Platform. We believe this will usher in a new era of
revenue-generating video services on pre-IMS and evolving IMS networks."

RADVISION's Multimedia Terminal Framework allows application developers to focus
on application development, hardware integration and user interaction rather
than complex VoIP standards when developing Customer Premise Equipment (CPE)
devices, such as IADs and WiFi Phones. This enables faster time-to-market. The
framework is a complete solution, encompassing signaling, call control and media
management. The SCOPIA Interactive Video Platform is an IMS-ready, carrier-grade
video-enabled media server with flexible APIs for development and deployment of
multiple interactive advanced multimedia services in converged networks.

"This joint development effort is a real springboard for full IMS deployment,
and complements our existing offerings in the mobile space," said Tsahi
Levent-Levi, Product Manager for RADVISION Technology Business Unit. "RADVISION
offers a complete line of technology products to develop IMS clients. Our
cooperation with Clique positions us to provide client application level
solutions using the jointly developed MVT and addresses the needs of customers
like service providers with turn-key application solutions that go beyond our
existing product line of enabling technology tools."


The Mobile Video Telephony client is available now from RADVISION or Clique for
customer demonstrations. Customization with carriers and OEM's of a SIP and
H.264 compliant Video Telephony Client is planned for late Q4 2007.

The new Mobile Video Telephony application will be showcased at the RADVISION
Booth #537 at VON Fall 2007 in Boston October 29-November 1.

RADVISION(R) Enhances SCOPIA(R) Unified Visual Communications Solution with
Advanced High Definition Capabilities Supporting Mixed Mode Conferences of
High Definition, Standard Definition and Desktop Users

Tuesday October 30, 7:00 am ET

SCOPIA V5.5, SCOPIA Desktop, and iVIEW(TM) Suite offer the most comprehensive HD
solution for enterprises, extending the room system environment to desktops for
large-scale, distributed deployment

BOSTON & TEL AVIV, Israel--(BUSINESSWIRE)--RADVISION (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 enhancements to its next generation SCOPIA platform,
including SCOPIA MCU, SCOPIA Desktop and the iVIEW Suite, to provide a
comprehensive and affordable solution for High Definition (HD) multipoint video
conferencing. The new version 5.5 is a system release with significant
enhancements across the product line.

SCOPIA V5.5 New Features and Functionality

The SCOPIA family of video conferencing and collaboration tools is a complete
unified communications solution that delivers a very cost-effective, high
quality video experience - anywhere and anytime. Enterprise users can enjoy
easy-to-use video connectivity at all levels of the organization - from users at
their desktops and on the road, to partners, colleagues and suppliers. The
single solution ensures reliable interoperability between different systems and
resolutions, such as 3G, standard definition (SD), high definition (HD) and
desktops.

The SCOPIA Multipoint Control Unit's (MCU) High Definition capabilities now
include HD Continuous Presence and the ability to mix HD and standard room
systems and desktops in the same call without all participants downgrading to
their common capabilities. With the SCOPIA platform's optimized capacity, users
receive maximum value for their investment based on the video application - for
example, if HD is not fully utilized, the number of available ports for Standard
Definition and Desktop increases for a reduced cost per port.

The new version of the innovative SCOPIA Desktop solution now leverages the
enhanced HD capabilities of the SCOPIA MCU along with adding productivity
enhancements, such as text chat, conference moderation, and waiting room
capabilities. SCOPIA Desktop extends the capabilities of the SCOPIA MCU to
remote users with a free, Web-based client, H.239 data collaboration, embedded
firewall and NAT traversal and conference streaming.

SCOPIA's iVIEW Suite management software, providing call distribution and
routing, reporting, scheduling, network management, and groupware integration,
has been enhanced to support the HD capabilities of the SCOPIA MCU. The iVIEW
Suite now provides High Availability redundancy, meeting the need for mission
critical HD conferencing in the enterprise.

The SCOPIA V5.5 portfolio is a complete Unified Visual Communications solution,
including desktop, Standard Definition, and High Definition multipoint
conferencing capabilities, gateway, gatekeeper, Web-based client, firewall
traversal, streaming, and overall application management providing the best
performance, pricing, and value available in the market today.





"Through SCOPIA and its SCOPIA Desktop offering, we can provide our constituents
a completely seamless solution that allows desktop and remote users to connect
to our existing video network infrastructure capable of High Definition
conferences," said Steve Cachia, Manager for Video Network Services, University
of Houston-Downtown Division of Information Technology. "RADVISION's advances
with the SCOPIA platform once again demonstrate our shared vision of what video
conferencing can do, and where it can and will take us."

"Wainhouse Research is pleased to see RADVISION enhance its SCOPIA platform to
support mixed mode conferences of High Definition, Standard Definition and
desktop users," said Ira Weinstein, Senior Analyst and Partner with Wainhouse
Research. "The company's unique method of processing High Definition on the
SCOPIA MCU combines HD video quality and cost effectiveness, making it well
suited for the mixed mode conferencing environments of today."

"Our approach to High Definition conferencing with the SCOPIA MCU, SCOPIA
Desktop, and iVIEW Suite represents RADVISION's unique capabilities to provide
value and benefits to our customers," said Zeev Bikowsky, GM of RADVISION's
Enterprise Business Unit. "Today's enterprises are steeped in the practical
environments of differing systems, like Standard Definition, desktops, and High
Definition room systems - all in the same conference. With these enhancements to
the SCOPIA platform, we also bring the benefit of extending High Definition room
conferencing to the desktop, which is truly extending the utility and reach of
the new breed of HD room systems available."

RADVISION will be exhibiting the SCOPIA V5.5 product lineup, including SCOPIA
Desktop and High Definition (HD) Continuous Presence video conferencing, at the
Fall 2007 VON Expo, October 30-31, Boston Convention and Exhibition Center,
Boston, Massachusetts, booth 537.

support required for call control services and multiple terminations. With
advanced call control services, support for a wide range of SIP specifications,
multiple terminations support, and "out-of-the-box" ease of use, the Multimedia

equipment and devices.

Texas Instruments uses TeamSpirit(R) 3.0 Voice&Video Engine Embedded that is a
highly optimized media processing solution which enables real-time voice &
video-over-IP calls. The solution is IMS-ready, so new revenue generating
applications and services can be implemented on wireline or wireless devices.
The engine supports miscellaneous signaling protocols, is adapted to deliver the
good quality over any network conditions and thus can be used on any network,
including Wi-Fi and 3G.

"Both technologies supplied by our partners, enable development of next
generation DaVinci-based consumer products including state-of-the-art video
features with closer, clearer and crisper video quality. Today's users demand
more than standard TV, they want excellent video call capabilities as well. With
SPIRIT and RADVISION, DaVinci enables this perfectly," says Arnaud Duclap, EMEA
business development manager, Digital Entertainment, Texas Instruments.

"SPIRIT's engines aim to deliver the highest-quality voice and video to
converged communication devices," says Slava Borilin, VP Products at SPIRIT. "We
have a strong pipeline of OEMs looking to license our voice/video engines for
the DaVinci platform. We are pleased to collaborate with RADVISION and TI, and
together believe we are setting a new quality standard for audio-visual
communications."

"RADVISION and SPIRIT have cooperated since our initial choice of SPIRIT
solutions in our developer products," says Adi Paz, Senior Director for
Marketing and Product Management with RADVISION Technology Business Unit.
"Together with TI, we are bringing new video telephony capabilities to the world
of next generation IMS-ready consumer electronics, such as IP-STBs, portable
multimedia players, media centers and more."
