RADVISION(R) Technology Selected by Leading UK Telecommunications
Systems Company

Monday July 16, 7:00 am ET

SCOPIA(TM) Interactive Video Platform and 3G Video Gateway Power Value Added
Services in Growing Small and Medium-Sized Enterprise Market

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 that telecom pioneer, 4com, one of the largest suppliers of
telecommunications technology to small businesses in the UK, is using the
SCOPIA(TM) Interactive Video Platform and 3G Video Gateway to power video
communication solutions.

4com specializes in offering voice and video communications solutions for small
to medium-sized businesses. Recognizing the advantages that video conferencing
and mobile interactive video services can deliver to this market in terms of
productivity, efficiency and supply chain management, 4com is dedicated to
providing advanced voice and video communications as well as mobile video
solutions to this growing sector.

The RADVISION SCOPIA Interactive Video Platform enables 4com to provide a video
portal that offers directory services and advertising for their user community.
Using the SCOPIA 3G Video Gateway both IP video endpoints and 3G handsets are
able to utilize the advanced media capabilities and flexibility of the SCOPIA
Interactive Video Platform.

The SCOPIA Interactive Video Platform, an IMS ready video media server, and the
SCOPIA 3G Video Gateway are the core infrastructure elements that enable the
deployment of converged interactive video services, connecting multiple
real-time video sources in UMTS, CDMA EV-DO, Cable and other IP networks.

"SMEs are always looking for new ways to differentiate themselves, and can
easily do so by visually communicating with their customers. Interactive mobile
video for applications, communications and video conferencing is a strong growth
engine for the small to medium-sized enterprise market, and will not only
increase operational efficiency, but also give companies a competitive
advantage," said Alon Barnea, General Manager of RADVISION Mobility & Service
provider Business Unit. "We are proud to play a role in the success 4com has
achieved and believe this market trend will fuel more usage and traffic in the
visual communications arena."


"RADVISION's advanced technology enables us to realize our vision to empower all
types of businesses - no matter how small - to reap the benefits of
video-enabled communications in the workplace," says Edward Bodiam, Director of
4com. "Our back-to-basics approach to video services makes this important method
of communications accessible to small and medium-sized enterprises, and
RADVISION helps us deliver the best service we can to our customers."

4com video communications solutions are available today and support both IP
endpoints and 3G mobile devices. Advanced video communications is helping 4com
customers increase customer retention and shorten business cycles, enhancing the
way people do business and contributing to efficiency and the environment by
reducing travel and waste.

"We were delighted to be involved in the early release of 4com's video
conferencing facility," said 4com customer Nik Little, Director of Emery Little
Insurance Brokers Ltd. in England. "The communication to our remote offices
which are spread around the country improved dramatically. A video call has much
more impact than just a voice call and indeed we conducted meetings via the
system which otherwise would have meant four-hour round trip journeys. The long
term prospects for this facility are very exciting."

RADVISION(R) Technology Powers Innovative Home Surveillance Service Deployed
Throughout Spain

Wednesday July 25, 7:00 am ET

Securitas Direct, Spain Provides 3G Home Surveillance System Based on
RADVISION's SCOPIA(TM) Interactive Video Platform and 3G Video Gateway

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 that its technology is powering an advanced 3G access and control
system for home surveillance. The security solution is developed by CESTEL, a
major Spanish system integrator and service provider and deployed by Securitas
Direct, a world leader in security systems.

The initial deployment targets an installation base of 7,000 households
throughout Spain. Home cameras, connected to the security system via ADSL can be
accessed by 3G subscribers, who are called when a manual or automatic alarm
triggers the system. The 3G subscriber may also dial-in to the system and obtain
direct access to the home surveillance camera whenever desired. The cameras and
other electrically controlled devices such as doors, gates and alarms can be
activated by the number pad on the 3G mobile phone. Utilizing the camera's built
in speaker and microphone, the solution enables 3G subscribers to verbally
communicate with the actual location where the camera is set.

"3G mobile access to surveillance cameras is a solution that our customers are
looking for," said Mr. Jose Luis Martin, Securitas Direct's CTO. "The solution
provided by RADVISION and CESTEL allows easy access to 3G video streams from any
device, anywhere, in real-time and with no need for a client download, resulting
in an efficient and manageable large scale deployment. The superior video
quality and smooth operation enhances our surveillance and security offerings
significantly."

The 3G integration application, developed by CESTEL with their 3G Builder(TM)
product and RADVISION's IMS ready SCOPIA(TM) Interactive Video Platform, is
based on network and device-agnostic infrastructure that enables remote cameras
to be accessed and operated by any 3G handset.

"Our ability to quickly develop the best system to comply with Securitas
Direct's forward looking requirements for the initial deployment is an excellent
example of the benefits of our continued partnership with RADVISION," said Mr.
Fernando Ortiz, CEO of CESTEL. "The SCOPIA Interactive Video Platform's flexible
API allowed us to implement together with the CESTEL 3G Builder(TM), an advanced
interactive video application for the security market, that combines 3G access
to security cameras' video streams, remote control of the cameras, bidirectional
audio, and access to recorded video streams. We are confident that our combined
solution provides the ease of use that Securitas Direct wants their customers to
enjoy."

"Securitas Direct and CESTEL are pioneering new paradigms in home surveillance
and security and leading the market towards widely-deployed remote interactive
multimedia access. The new systems are not only technologically viable, but
their ease of use and ubiquitous availability offers commercial promise and
potential. The remote voice and video communications service is also appealing
for personal monitoring of the elderly, nannies, babysitters, household pets and
more," said Alon Barnea, General Manager of RADVISION's Mobility & Service
Provider Business Unit. "This video-based home surveillance service is further
testimony to the importance of advanced scalable interactive mobile video
communications, combining real-time external media sources and bidirectional
video, fulfilling various day to day needs that are now becoming part of the
telecom landscape."
