RADVISION(R) To Demonstrate Advanced Video Solutions for Unified  Communications
at Spring VoiceCon 2007

Monday March 5, 7:00 am ET

Company Will Exhibit New Solution to Connect Remote Users, Advanced High
Definition Video Conferencing Capability, and Video Integration for IBM Lotus
Sametime ORLANDO, Fla & 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 during March 5th - 7th at the
VoiceCon exhibition in Orlando, RADVISION will demonstrate multiple technology
advancements and significant enhancements for unified visual communications.

At VoiceCon booth 1135, RADVISION will be showcasing:

     o    The  introduction  of SCOPIATM  Desktop - a  revolutionary  new way to
          connect  traditional  room based video  conferencing  with desktop and
          remote users.

     o    Advanced HD (High Definition) conferencing.

     o    Innovative video integration with IBM Lotus Sametime.

The Introduction of SCOPIA Desktop

Until now, video conferencing has been mostly confined to the conference room.
Users have benefited from the value of voice, video and data collaboration
between conference rooms but there has been no simple way to include users at
their desktops or remote users on laptops that did not involve complex software
installations, expensive licensing fees or firewall traversal problems.
RADVISION's SCOPIA Desktop eliminates these issues. It provides an extension to
any room system based videoconferencing deployment by allowing remote users to
connect to a conference and fully participate with audio, video and data
collaboration as if they were all in the same room. SCOPIA Desktop uses a freely
distributable web based plug-in that can be used by anyone inside or outside the
enterprise firewall. It is now simple to connect to and fully participate in
meetings no matter where users are - at their desk, at a customer location or in
a hotel across the world.

Advanced HD (High Definition) Conferencing

Following on from RADVISION's market leading support for High Definition (HD)
video conferencing, RADVISION will demonstrate support of High Definition
Continuous Presence that will allow conferences with a mix of HD and Standard
Definition (SD) endpoints. This latest technology bridges the thousands of SD
devices to the new world of HD. It allows each endpoint user to participate in
the conference at the highest quality the endpoint is capable of without
degrading every device to the lowest common denominator and thus maximize their
enjoyment of seeing everyone using Continuous Presence.

Innovative Video Integration with IBM Lotus Sametime

RADVISION brings advanced conferencing capability to IBM's unified
communications and collaboration product, Lotus Sametime. By adding RADVISION's
unique multi-window video and audio plug-in to Lotus Sametime, users can
escalate Lotus Sametime instant messaging chat sessions into full multiparty
audio and video sessions and extend those conferences to other devices such as
standards-based video conferencing systems, 3G videophones or virtually any
telephone or cell phone available today.






"RADVISION continues to develop powerful new visual collaboration solutions to
support the advanced conferencing environments being developed by our
market-leading partners, including Cisco's high definition and Telepresence
offerings and IBM's Lotus Sametime," said Bob Romano, RADVISION's VP of
Enterprise Marketing. "With our introduction today of SCOPIA Desktop and our
advanced SCOPIA platform with High Definition Continuous Presence, we have taken
our support of our partners a major step forward in providing what the market is
demanding for combined voice, video and data communications solutions."

RADVISION(R)  SIP  Server  Platform  V3.0  Sets New  Standards  for SIP  Service
Creation

Monday March 19, 9:00 am ET

Introducing a Modular Service Creation Framework for Rapid Development of High
Performance SIP Application Servers, Session Border Controllers, FW/NAT Servers,
Controllers, such as MGCF, BGCF, MRFC, Gateways, Call Control Servers, IMS Call
Session Control Functions and More

SAN JOSE, Calif. & 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 the release of version 3.0 of its
market-proven SIP Server Platform.

The RADVISION SIP Server Platform introduces a modular, flexible Service
Creation Framework to the industry. Using pre-defined "service components,"
customers can leverage the investment in off-the-shelf service building blocks
to quickly develop advanced high-performance services in a plug-and-play modular
architecture. The new architecture features a level of customization and
flexibility that was not previously available. For SIP service developers, this
translates into significantly shorter development cycles and greater
flexibility.

Version 3.0 of the SIP Server Platform also employs a unique High Availability
mechanism which features intelligent layer-7 load-balancing and reliable
switchover capabilities, optimal hardware utilization and minimal failover
recuperation time. This results in consistent, robust performance, superior
response time to failures and allows dynamic scalability and flexible
maintainability with no downtime.

"With the release of version 3.0 of our SIP Server Platform, RADVISION is
setting a new standard in terms of flexible, rapid development," said Zeev
Bikowsky, General Manager of RADVISION's Technology Business Unit. "Using the
modular elements of our Service Creation Framework, developers can now implement
differentiating services in a fraction of the time - reducing operational costs
and generating revenues. High availability is a very important feature for
reducing operational costs, increasing service revenues for operators and
improving customer satisfaction."

In addition, version 3.0 introduces many other new features including
accounting, IMS functionality and solutions for scalability, redundancy,
security and protection.

The SIP Server Platform is available for all major operating systems and
features high portability and interoperability. The flexible framework allows
developers to focus on the differentiating features of their applications and
significantly shorten development cycles for rapid time-to-market. High
maintainability and manageability allow reducing the total cost of ownership for
end users.

The RADVISION SIP Server Platform is part of the RADVISION IMS Express(TM) -
Complete IMS Developer Suite - the most comprehensive solution for developers of
next generation IMS network elements. The Suite includes all the signaling and
media protocol toolkits, development frameworks, and testing tools needed to

RADVISION Chairs Leading Industry IMS Interoperability Group

Wednesday March 28, 7:00 am ET

The IMTC IMS Activity Group Focuses on Industry-Wide Interoperability of
Terminal-Network Signaling and Media

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, announced
today a new activity group has been formed by the International Multimedia
Telecommunications Consortium (IMTC) dealing with interoperability issues
related to the IP Multimedia Subsystem (IMS). The activity group currently
includes among its members representatives from leading companies in the
telecommunications industry, such as Ericsson, Motorola, NMS Communications,
Nokia Corporation, Samsung Electronics, Sharp Corporation and Sony Ericsson
Mobile Communications. Tsahi Levent-Levi, a Product Manager in RADVISION's
Technology Business Unit, was chosen to chair the activity group. IMTC has been
involved for over a decade in interoperability testing and has been a driving
force in the adoption and deployment of mature H.323 and 3G-324M devices and
networks.

The IMTC IMS activity group promotes and facilitates the development and
implementation of interoperable multimedia conferencing solutions based on open
international standards, as well as other standards organizations. The
proliferation of open standard solutions will advance the multimedia
conferencing industry and further its widespread deployment. In order to do
this, the IMTC IMS activity group focuses on interoperability of end-to-end
functionality and terminal-network signaling and media. In addition, the IMS
activity group finalizes IMS client application specifications, creates test
specification and implementation guides, and organizes test events. This
includes performing and documenting well-planned and controlled interoperability
tests, as well as planning, executing, and tracking rigorous interoperability
tests for the benefit of participating member companies. The activity group
reports feedback to 3GPP, 3GPP2, GSMA and other standard developing
organizations to apply the knowledge gained through testing to improve relevant
standards.

The IMTC IMS activity group also allows competing companies to conduct regular
dialogue regarding interoperability of their products and to develop a common
stance enabling them to help shape and evolve industry-wide standards.

The Evolution to IMS

The IP Multimedia Subsystem (IMS) is a standardized Next Generation Networking
(NGN) architecture that meets an important need in the growing trend towards
fixed, wireless and mobile network convergence. The IMS core network enables
operators and service providers to deliver identical IP services to both fixed
and mobile customers over any access. As IMS is the cornerstone of converged
telecommunications, it offers unique opportunities for the development of
next-generation devices and equipment and converged mobile communications.
RADVISION is leading the IMS evolution with the RADVISION IMS Express(TM), a
complete IMS Developer Suite. These IMS developer tools and IMS-ready
infrastructure products provide all the necessary protocol toolkits, IMS
application servers, IMS testing tools, and an IMS client package for terminal
developers - complete with application engines in addition to the underlying
signaling and media technology.

"RADVISION has always placed interoperability as a top priority, in the belief
that this will serve to advance the industry and bring about innovation," said
Adi Paz. "The advent of IMS underscores the importance of interoperability
across all spheres. Our chairing this Activity Group enhances the quality of our
IMS Developer Suite significantly."
