RADVISION Signs New Distribution Agreement with Imago

Wednesday December 20, 7:00 am ET

RADVISION's Video Network Infrastructure, Desktop and 3G Products Complement
Imago's Impressive Portfolio of Videoconferencing Products from Leading Vendors

FAIR LAWN, N.J.--(BUSINESS WIRE)--RADVISION(R) (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, announced
today that it has entered into a marketing and distribution agreement with Imago
Group PLC, Europe's largest distributor of videoconferencing products. The
agreement, which closed in September 2006, is expected to boost sales in several
key markets, most notably the UK and France.

"We are excited about our alliance with RADVISION," said James Vickerage, Head
of Marketing for Imago. "Endpoint-agnostic video network infrastructure
strengthens our portfolio significantly, along with the addition of innovative
3G capabilities and a scalable desktop conferencing platform like Click to
Meet(R). These will open many opportunities for qualified Imago resellers. We
are witnessing strong growth in demand for video-based communications from
resellers that do not specifically specialize in videoconferencing. RADVISION's
interoperable platforms for scalable desktop and mobile deployment will deliver
real added value to their offerings."

Under the agreement, Imago will market, distribute and support RADVISION's full
line of products, including the SCOPIA v.5 platform, SCOPIA 3G Gateway and the
award winning Click to Meet desktop collaboration suite, to qualified resellers.
Imago Group PLC has offices throughout the UK and France.

"In addition to offering highly practical and competitive bridging solutions,
RADVISION's videoconferencing endpoint-independent infrastructure will help us
penetrate new market segments," added Nicolas Jouan, Managing Director of Imago
France.

"Imago is an important player in the videoconferencing space, with broad reach
in key markets," said Bob Rickwood, General Manager of RADVISION's operations in
Europe, Middle East and Africa. "Adding our solutions to Imago's rich portfolio
of equipment from leading manufacturers, including several of our partners, will
give RADVISION a much stronger presence in the UK, France and Germany as well as
in China, where Imago is also active. We look forward to working together to
deliver more powerful unified communications solutions to customers in the
enterprise, government and education markets."
