ITEM 1 Press Release Source: RADVISION RADVISION(R) To Demonstrate Advanced Video Solutions for Unified Communications at Spring VoiceCon 2007 Monday March 5, 7:00 am ET Company Will Exhibit New Solution to Connect Remote Users, Advanced High Definition Video Conferencing Capability, and Video Integration for IBM Lotus Sametime ORLANDO, Fla & 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 that during March 5th - 7th at the VoiceCon exhibition in Orlando, RADVISION will demonstrate multiple technology advancements and significant enhancements for unified visual communications. At VoiceCon booth 1135, RADVISION will be showcasing: o The introduction of SCOPIATM Desktop - a revolutionary new way to connect traditional room based video conferencing with desktop and remote users. o Advanced HD (High Definition) conferencing. o Innovative video integration with IBM Lotus Sametime. The Introduction of SCOPIA Desktop Until now, video conferencing has been mostly confined to the conference room. Users have benefited from the value of voice, video and data collaboration between conference rooms but there has been no simple way to include users at their desktops or remote users on laptops that did not involve complex software installations, expensive licensing fees or firewall traversal problems. RADVISION's SCOPIA Desktop eliminates these issues. It provides an extension to any room system based videoconferencing deployment by allowing remote users to connect to a conference and fully participate with audio, video and data collaboration as if they were all in the same room. SCOPIA Desktop uses a freely distributable web based plug-in that can be used by anyone inside or outside the enterprise firewall. It is now simple to connect to and fully participate in meetings no matter where users are - at their desk, at a customer location or in a hotel across the world. Advanced HD (High Definition) Conferencing Following on from RADVISION's market leading support for High Definition (HD) video conferencing, RADVISION will demonstrate support of High Definition Continuous Presence that will allow conferences with a mix of HD and Standard Definition (SD) endpoints. This latest technology bridges the thousands of SD devices to the new world of HD. It allows each endpoint user to participate in the conference at the highest quality the endpoint is capable of without degrading every device to the lowest common denominator and thus maximize their enjoyment of seeing everyone using Continuous Presence. Innovative Video Integration with IBM Lotus Sametime RADVISION brings advanced conferencing capability to IBM's unified communications and collaboration product, Lotus Sametime. By adding RADVISION's unique multi-window video and audio plug-in to Lotus Sametime, users can escalate Lotus Sametime instant messaging chat sessions into full multiparty audio and video sessions and extend those conferences to other devices such as standards-based video conferencing systems, 3G videophones or virtually any telephone or cell phone available today. "RADVISION continues to develop powerful new visual collaboration solutions to support the advanced conferencing environments being developed by our market-leading partners, including Cisco's high definition and Telepresence offerings and IBM's Lotus Sametime," said Bob Romano, RADVISION's VP of Enterprise Marketing. "With our introduction today of SCOPIA Desktop and our advanced SCOPIA platform with High Definition Continuous Presence, we have taken our support of our partners a major step forward in providing what the market is demanding for combined voice, video and data communications solutions."

The activity group currently includes among its members representatives from leading companies in the telecommunications industry, such as Ericsson, Motorola, NMS Communications, Nokia Corporation, Samsung Electronics, Sharp Corporation and Sony Ericsson Mobile Communications. Tsahi Levent-Levi, a Product Manager in RADVISION's Technology Business Unit, was chosen to chair the activity group. IMTC has been involved for over a decade in interoperability testing and has been a driving force in the adoption and deployment of mature H.323 and 3G-324M devices and networks. The IMTC IMS activity group promotes and facilitates the development and implementation of interoperable multimedia conferencing solutions based on open international standards, as well as other standards organizations. The proliferation of open standard solutions will advance the multimedia conferencing industry and further its widespread deployment. In order to do this, the IMTC IMS activity group focuses on interoperability of end-to-end functionality and terminal-network signaling and media. In addition, the IMS activity group finalizes IMS client application specifications, creates test specification and implementation guides, and organizes test events. This includes performing and documenting well-planned and controlled interoperability tests, as well as planning, executing, and tracking rigorous interoperability tests for the benefit of participating member companies. The activity group reports feedback to 3GPP, 3GPP2, GSMA and other standard developing organizations to apply the knowledge gained through testing to improve relevant standards. The IMTC IMS activity group also allows competing companies to conduct regular dialogue regarding interoperability of their products and to develop a common stance enabling them to help shape and evolve industry-wide standards. The Evolution to IMS The IP Multimedia Subsystem (IMS) is a standardized Next Generation Networking (NGN) architecture that meets an important need in the growing trend towards fixed, wireless and mobile network convergence. The IMS core network enables operators and service providers to deliver identical IP services to both fixed and mobile customers over any access. As IMS is the cornerstone of converged telecommunications, it offers unique opportunities for the development of next-generation devices and equipment and converged mobile communications. RADVISION is leading the IMS evolution with the RADVISION IMS Express(TM), a complete IMS Developer Suite. These IMS developer tools and IMS-ready infrastructure products provide all the necessary protocol toolkits, IMS application servers, IMS testing tools, and an IMS client package for terminal developers - complete with application engines in addition to the underlying signaling and media technology.
