TEL AVIV, June 12, 2007 --RADVISION (Nasdaq: RVSN), 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 HaiVision Systems Inc. (Montreal, Canada), a leader in high performance network video technology, delivers Session Initiation Protocol (SIP) interoperability of its hai1000 product based on the RADVISION SIP Protocol Toolkit. This development, incorporated into HaiVision’s Invitation™ feature for the hai1000 multi-stream codec for telepresence, allows high performance network video technology to communicate with traditional video conference endpoints.

“With RADVISION’s support, HaiVision is introducing the first product that can seamlessly bridge the gap between high performance telepresence systems and traditional conferencing endpoints,” explains Francois Gariepy, HaiVision’s president. “Now within a multi-point telepresence session executives can invite external participants to contribute regardless of their conferencing platform.”

“We selected RADVISION because of their cross platform expertise,” continues Gariepy. “They have knowledge and extensive experience in both the IP/telecom and conferencing sectors.”

“We are excited about HaiVision’s efforts in joining together network video with videoconferencing,” states Sagi Subocki, Product Manager with RADVISION’s Technology Business unit. “SIP is the progressive standard for interaction between communications systems at all levels.”
