TEL AVIV, Israel--(BUSINESS WIRE)--RADVISION (Nasdaq: RVSN - News), a leading
provider of video network infrastructure and developer tools for unified visual

announced that its ProLab 3G-324M Test Solution was purchased by NTT DoCoMo.

NTT DoCoMo commented that the decision to purchase the ProLab 3G-324M Test

family of testing solutions for RADVISION's Technology Business Unit, said: "The
fact that ProLab was bought by an operator of NTT DoCoMo's stature is an honor
for RADVISION. The ProLab 3G-324M testing solution was also certified by GCF and
PTCRB. RADVISION will add more features to the ProLab family of testing and
analysis solutions, not only for 3G-324M, but also for NGN (Next Generation
Networks) for customers to easily execute high level tests in a shorter period."

          Procedure (MONA). MONA is a group of complementary techniques designed
          to significantly  reduce delay in H.324 call setup time. These include
          Accelerated Connect Procedure (ACP) and Media  Preconfigured  Channels

RADVISION(R) Technology Delivers IPTV Set Top Box Solutions

Tuesday April 17, 7:00 am ET

New Intel Media Processor Offers Advanced Videophone Capabilities Powered by
RADVISION Technology

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 networks, today
announced that the company's Multimedia Terminal Framework and Advanced RTP
Toolkit is bringing new IP video-based communications capabilities to the Set
Top Box (STB) when coupled with the new Intel(R) ICE 2110 Media Processor.

"We are excited to be working with RADVISION to bring video-based personal
communications to the Set Top Box," said William O. Leszinske, Jr., General
Manager of Intel's Consumer Electronics Group. "Consumers have more choices than
ever before with new services, such as video phone and video conferencing.
Intel's new media processor enables the delivery of these services to the home
while providing headroom for future services."

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 IP Set Top Boxes, as well as other
Customer Premise Equipment (CPE) devices, such as wireline and wireless
terminals, IADs, and mobile handsets. This enables faster time-to-market. The
framework is a complete solution; encompassing signaling, call control and media
management.

RADVISION is developing the entire videoconferencing application for Intel's
media processing platform, integrating third party audio and video codecs with
the platform's peripherals, and developing a reference application for OEMs.
This is enabling rapid development and short time-to-market, while maintaining
high flexibility and extensibility.

"At RADVISION we believe that the IP STB will soon be the epicenter of
communications in the home," added Zeev Bikowsky, General Manager of RADVISION's
Technology Business Unit. "IP-based videoconferencing technology opens the door
to an unlimited number of new, compelling value-added services for the digital
home, based on strong networked media platforms like Intel's. RADVISION's
ability to offer a complete solution will help operators build these services."
