RADVISION(R) Announces General Availability of H.460 Standard Firewall
and NAT Traversal Solution for Video Conferencing

Tuesday August 7, 7:00 am ET

SCOPIA(R) PathFinder(TM) v5.5 Solves Firewall Issues for Both Internal
Enterprise Users and Remote Sites

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 availability of SCOPIA PathFinder version 5.5. This end-to-end
firewall and NAT traversal solution now includes H.460 support enabling H.460
compliant endpoints to connect without the need for any intermediate client in
the connection stream. SCOPIA PathFinder is the only solution available in the
market that handles both endpoints with embedded H.460 support and endpoints
without H.460 capabilities, without the need for additional hardware or
traversal software.

SCOPIA PathFinder is a complete firewall traversal and NAT solution, offering
both a near-end (enterprise network) and far-end (remote site) solution. SCOPIA
PathFinder maintains the security and advantages of firewall and NAT, while
opening up IP visual communication capabilities to telecommuters, workers on the
move, customers and suppliers. SCOPIA PathFinder assures the quick and easy
establishment of vital communications beyond the firewall boundaries of the
enterprise.

H.460 is a set of ITU standards which defines protocols for firewall traversal.
H.460 compliant conferencing endpoints will connect directly to Pathfinder for
connectivity through firewalls. For non-H.460 endpoints, free SCOPIA PathFinder
client software can be deployed at remote sites providing firewall traversal via
PathFinder.

SCOPIA PathFinder v5.5 Highlights:

     o    Solves near-end and far-end firewall issues without any changes to the
          firewall.

     o    Works with any H.323 endpoint, gatekeeper, and firewall.

     o    Supports any H.460 compliant conferencing system.

     o    Includes free software for endpoints that do not support H.460.

     o    Supports AES encryption for all traffic.

     o    Enables URI dialing (email or URL style addressing).

"As one of the main contributors in perfecting the H.460 standard, RADVISION is
committed to providing highly interoperable standard based conferencing
solutions. RADVISION collaborated with the ITU in order to define the standard
and bring about its ratification," said Eli Doron, President and Chief Strategy
Officer, RADVISION. "Now that we have incorporated this capability into our
SCOPIA PathFinder product, enterprises can easily communicate through firewall
boundaries, and IT managers can maintain critical security boundaries whether
the conferencing system is H.460 compliant or not."

"SCOPIA PathFinder has enabled enterprises to deploy a more flexible video
conferencing solution by eliminating the issues of traversing network
boundaries. This has enabled conferencing across all enterprise locations or to
partners or customers outside the organization," said Bob Romano, RADVISION's VP
of Enterprise Marketing. "H.460 further extends the power of an enterprise's
video network infrastructure without creating those undesired security holes."
