RADVISION Launches SCOPIA(R) IVP 3.0 Media Server Enabling a
Wide Range of Personalized Video Services

Monday July 28, 9:00 am ET

Enterprises and Service Providers can now leverage a powerful general purpose
media server with a flexible high-level API, and a unique Service Creation
Environment, to easily generate services with ubiquitous connectivity.

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 networks, today
announced the worldwide availability of its SCOPIA IVP 3.0 media processing
server.

SCOPIA IVP 3.0 offers an unparalleled-in-market combination of:

     o    Powerful media processing;

     o    Ease of service creation and customization;

     o    Ubiquitous service connectivity;

     o    Unique web app / content to 3G mobile rendering; and

     o    High scalability.

The SCOPIA Interactive Video Platform (IVP) is designed to play a critical and
vital role in the way service providers, enterprises and developers create and
reliably deploy interactive video services for seamless integration with
existing networks.

"SCOPIA IVP is a smart delivery platform that determines the individual
capabilities of end-user devices and seamlessly delivers top video quality for
each user based on the capabilities of their end point or network connectivity,
supporting 3G handsets, IP Phones, desktop soft clients, video room systems and
more, including seamless traversal of FW / NAT between user's endpoint and IVP,"
said Zeev Bikowsky, General Manager of RADVISION's Networking Business Unit.

Featuring advanced and powerful processing capabilities, SCOPIA IVP allows
enterprises and service providers to combine interactive live and stored content
on one screen; personalize video services; enable "Context-Aware" services; and
build social and community video applications for entertainment or for business.

SCOPIA IVP's open, rich and flexible API enables the creation of any video
application by leveraging easy to use, powerful DSP-based media processing
building blocks.

Starting from a range of simple off-the-shelf applications, such as Video IVRs
to the most demanding multiparty/full featured solutions requiring transcoding
and advanced media processing functionalities, SCOPIA IVP enables enterprises
and service providers to constantly extend their applications as their business
grows.

Rapid Application development

To enable this, a powerful Service Creation Environment (SCE) - offered by
RADVISION and its partners - allows developers to rapidly create video
applications using standard environments such as Java, HTML and even graphical
"drag & drop" tools, as easily as if they were developing for the Web.

This includes a unique solution for seamless rendering applications and content
developed for the web, on any mobile 3G-enabled handset accessible by making a
regular 3G phone call.






Developer Community

To further build on the strengths of its media server, an active community of
partners and developers is working together with RADVISION to offer a variety of
new and compelling video applications built on top of the SCOPIA IVP platform.
This community supports tailored development of applications to meet the unique
needs of a wide range of companies.

RADVISION Video Enables Cisco Contact Center

Tuesday July 29, 9:00 am ET

RADVISION's SCOPIA Interactive Video Platform Enables Cisco's Unified Customer
Voice Portal (CVP) with Video Communications

TEL AVIV--(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 that it is providing integrated video communications for Cisco's
Unified Customer Voice Portal (CVP). Cisco's solution will now leverage the
SCOPIA Interactive Video Platform's extensive video communications capabilities.

The SCOPIA Interactive Video Platform (IVP) is a universal video media server
platform providing powerful processing building blocks, ubiquitous device
connectivity and enabling the easy creation of a wide range of video-related
applications and services. The video integrated Cisco CVP solution utilizes
RADVISION's iCONTACT, a unique contact center video-enabling software component
running in conjunction with the SCOPIA Interactive Video Platform. Together, the
SCOPIA IVP and iCONTACT offer a comprehensive solution that enables systems
integrators and contact center equipment vendors to develop and deploy visual
communications services to contact centers.

Using Cisco Unified Customer Voice Portal, organizations can provide
intelligent, personalized self-service over the phone, allowing users to
efficiently retrieve the information they need from a contact center. Customers
can use touch-tone service or their own voice to request information with
self-service, and, if live agent assistance is requested, Cisco Unified Customer
Voice Portal can transfer information given by the customer and the call itself
to the agent, resulting in a smooth customer service experience. Now with
RADVISION's SCOPIA Interactive Video Platform, Cisco Unified Customer Voice
Portal can support video interactions, including self-service, queuing, and
agents.

Video adds a new dimension to the traditional contact center; the dimension of
sight and enables an entirely new realm of communications offering users a
unique video telephony experience, streamlining operations, and boosting service
levels and cutting expenses. This new call center capability harnesses the power
of visual communications and can change the nature of customer interactions.
Video enabling Cisco Unified Customer Voice Portal with the SCOPIA Platform
provides the following features and benefits:

     o    Video menus for a more intuitive caller experience

     o    Video  self-service  where  prerecorded  or live  videos can be played
          enabling richer interactions

     o    Video queuing where videos can be played while waiting for an agent

     o    Video agent support  providing a unique  customer  service  experience
          that builds trust

     o    Video agents can "push" additional  pre-recorded or live video content
          to callers,  providing an efficient,  standardized  method for sharing
          information and instructions.

     o    Support for 3G video-enabled mobile devices and video kiosks for broad
          user access and reach.

"As organizations become more dispersed and in-person meetings become an
expensive luxury, electronic communication is quickly becoming the default way
of communicating. Video greatly accelerates building trust between parties
especially when they have never seen each other before," said Boaz Raviv, CEO of
RADVISION. "RADVISION's SCOPIA Interactive Video Platform puts a live face to a
name, delivering increased customer satisfaction ultimately leading to a more
profitable business."
