RADVISION  and Nortel Team to  Demonstrate  3G Video  Community  Service at CTIA
Wireless Exhibition 2006

Wednesday April 5, 8:30 am ET

RADVISION's Interactive Video Platform Completes Incubation with Nortel's CDMA
1xEV-DO Rev A Platform Live Video Community Application Demonstrates Innovative
3G Service FAIR LAWN, N.J.--(BUSINESS WIRE)--April 5, 2006--RADVISION (Nasdaq:
RVSN - News), a leading provider of multimedia conferencing and communications
platforms, today announced an innovative video community application will be
demonstrated at the CTIA Wireless 2006 Show in Las Vegas, based on RADVISION's
Interactive Video Platform and Nortel's 1xEV-DO Rev A access platform.

The demonstration shows multiple parties communicating in a video chat
environment known as a video community. This innovative application is targeted
at 3G operators to be deployed as a revenue generating and customer retention
service.

Based on the RADVISION Interactive Video Platform, the video community service
is able to combine video streams from any IP source including video from 3G
subscribers' PC's and camera phones streaming content network sources, including
pre-recorded and live broadcasts. The Interactive Video Platform combines the
various video sources and presents them to the subscribers as a unified picture
comprised of several video images that are adjusted and positioned clearly on
the mobile screen. The Interactive Video Platform includes a flexible software
development interface so that the video service to be deployed by the operator
may be quickly created, customized and adapted to the exact needs of the
subscriber base without the need to change the client device application.

The RADVISION Interactive Video Platform is already deployed in IMS networks
around the world supporting a variety of services including 3G video
conferencing, PC to Mobile video conferencing, and video-enabled contact
centers.

"RADVISION's Interactive Video Platform enables the creation of compelling new
video applications for 3G subscribers. In addition to RADVISION's 3G
videoconferencing services and video community demonstration application, the
Interactive Video Platform is a flexible video service creation platform that
can be used to deploy different types of services ranging from surveillance
services to video-enabled contact centers. Our commitment to open standards,
including MMD/IMS, promises a smooth and highly interoperable migration for
operators deploying our products. We are excited about our cooperation with
Nortel and the fact that we have successfully completed incubation with their
1xEV-DO Rev A access" said Dr. Amnon Gavish, VP of Service Provider Business
Development in RADVISION.

Nortel is providing the access and core components for deployment on CDMA EVDO
networks. These components will drive the migration from legacy circuit switched
architecture to an all IP network that simplifies and standardizes the way that
advanced services, including multimedia, are delivered across the network to
subscribers.

Nortel will be demonstrating the video community application running on a CDMA
1xEV-DO Rev A along with RADVISION's Interactive Video Platform at the Nortel
booth at CTIA Wireless 2006 Exhibition, Las Vegas, Nevada, during April 5-7.

announces today that Compal Communications Incorporated (CCI) has licensed
RADVISION's leading 3G-324M protocol toolkit, along with professional consulting
services, for development of an advanced 3G cellular video Windows Mobile(TM)
PDA phone.

The CCI 3G PDA phone includes an advanced video application that will allow
subscribers to videoconference and participate in video communities and other
revenue generating services. The phone is based on Microsoft(R) Windows Mobile

to the mobile market segment. Barry Evans, General Manager of Intel's
Application Processor Business Unit commented "Our Intel XScale(R) processors
are an outstanding solution for devices in this demanding market segment. The
advanced video application that RADVISION has developed underscores how
compelling this device is as a platform for mobile multimedia applications."

operating system meets the performance, features and strict memory requirements
of cutting edge mobile embedded devices. Jason Lim, Regional Director, Asia
Pacific & Japan, Mobile and Embedded Devices Division, Microsoft Corp. added,
"We have worked closely with RADVISION in the past, and the successful
