Fair Lawn, New Jersey, November 16, 2005 -- RADVISION LTD. (Nasdaq: RVSN) a leading provider of multimedia conferencing and communications platforms, announced the introduction of the latest version of its SCOPIA™ 3G Video Gateway for use when deploying rich media solutions in new or existing networks.

The new SCOPIA 1000 3G Video Gateway features unprecedented scalability, and it easily handles implementations that range from small, entry-level applications all the way up to large-scale, carrier-grade, high-capacity mass service deployments. The SCOPIA 3G Video Gateway benefits from a new, higher-capacity chassis that triples the capacity of former gateways and offers carrier-grade, fully redundant support with dual interfaces and dual power supplies for high availability and increased reliability. In addition, RADVISION's SCOPIA 3G Gateway is equipped with extensive administration and management features to ease operation and maintenance.

This latest version of the SCOPIA 3G Video Gateway delivers an improved user experience through substantial reductions in call setup time. SCOPIA features built-in support for WNSRP, the only standardized call setup time reduction technique for real-time 3G multimedia services and the proposed ACN solution for reduced call setup time. It also features enhanced audio and video quality which was achieved through the use of advanced audio codec’s, intelligent video packet technologies and the seamless handling of audio calls to simplify user dialing plans.

In addition, the SCOPIA 3G Video Gateway offers new levels of administrative security, including HTTPS support, physical/logical separation of media and management, and the use of access control lists.

Delivering seamless video telephony and streaming connectivity between 3G-324M enabled mobile devices and IP networks, the entry level SCOPIA 400 and carrier grade SCOPIA 1000 3G Video Gateway automatically perform full protocol conversions between 3G-324M, SIP, H.323, RTSP, and H.320 (ISDN).

"These latest enhancements to the SCOPIA 3G Video Gateway underscore RADVISION's commitment to the successful deployment of 3G and IP video telephony," noted Eli Doron, RADVISION’s CTO. "RADVISION is continuously involved with real world deployments, which allows us to lead the industry and proactively deliver the innovations required for this dynamic 3G market.”
