The ITU  Approves  WNSRP  Standard for  Fast-Call  Setup  Solution  Supported by
Radvision

Tuesday September 6, 9:00 am ET

ITU Study Group 16 has approved WNSRP, the only standardized solution that
reduces call setup time for real-time 3G-324M multimedia services. FAIR LAWN,
N.J.--(BUSINESS WIRE)--Sept. 6, 2005--RADVISION (Nasdaq: RVSN - News) today
announced that the ITU has granted initial approval of WNSRP, a powerful new
technical solution that dramatically improves call setup time in 3G-324M
multimedia systems.

3G broadband mobile networks and advanced handsets are beginning to make
wireless video a commercial reality. The success of emerging video-based
services, such as video telephony and conferencing, video-on-demand, remote
surveillance, and other real-time services, is impacted by lengthy setup times
traditionally associated with streaming video and video conferencing.

WNSRP, supported by major operators, handset manufacturers, and their suppliers,
is the only standardized call setup reduction solution for real-time 3G
multimedia services in the industry today. RADVISION has been a strong supporter
of the new standard and is marketing the first 3G video services gateway
incorporating WNSRP available today.

"As 3G video devices proliferate in the market, standardizing a call setup
solution becomes even increasingly relevant to market and technical success,"
said Boaz Raviv, General Manager of RADVISION's Technology and Networking
Business Units. "Other wireless markets have proven that proprietary solutions
are not satisfactory. Working together as an industry, we have developed a
superior approach to call setup with WNSRP."

Extensive testing of WNSRP has shown it to be backward compatible with currently
marketed handsets, as required of a robust standard. The new standard was
already implemented by many companies prior to its final approval and members of
the consortium have independently tested their products.

RADVISION's 3G-324M Toolkit, ProLab 3G, and SCOPIA 3G Video Gateway products
support WNSRP. "RADVISION is dedicated to providing a superior user experience
in multimedia systems," said Boaz Raviv, General Manager of RADVISION's
Technology and Networking Business Units. "By using RADVISION products, such as
our 3G Gateway, developers can quickly implement WNSRP and gain significant
competitive advantages for their real-time video services products."

Developers working on 3G-324M video telephony systems can test design
interoperability through RADVISION's online 3G-324M IOT facility.

WNSRP Addresses a Technical Challenge

Call setup time was one of the last remaining challenges for real-time 3G video
services. The "time outs" and retransmissions of the previous approach added to
the already extensive setup time and introduced long delays that consumers were
no longer willing to accept for video services. The WNSRP standard is based on a
powerful new approach to call signaling that eliminates the message queuing and
"time out" issues that are inherent with the 3G-324M standard. Missed messages
are immediately detected and retransmissions are spontaneously generated leading
to shorter call setup times and bringing video connectivity close to the same
level of service as traditional telephony.








Looking beyond WNSRP to further improve call setup time, RADVISION has presented
a complementary addition to WNSRP, which reduces call setup time to a single
second. Known as ACN (Automatic Connect Negotiation), this proposed addition to
the H.324 standard works seamlessly with WNSRP and uses the H.245 control
channel to perform procedures in parallel during call setup. When combined,
WNSRP and ACN result in the only standards-based fast call setup solution in the
industry.
