ITEM 1 Press Release Source: RADVISION RADVISION and Clique Deliver End-to-End Video Solution Monday October 29, 7:00 am ET Joint marketing and development efforts will bring new interactive mobile video telephony client application to market * See live demo at VON Fall 2007 in Boston 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 today that it has joined forces with Clique Communications, Inc., a leading provider of IP video communication solutions, to jointly develop a new video telephony client application for mobile devices. The mobile video client application, focused on delivering superior video quality and an enhanced user experience, is being developed using RADVISION's Multimedia Terminal Framework. By bundling RADVISION's SCOPIA Interactive Video Platform with the new Mobile Video Telephony (MVT) application, RADVISION is uniquely poised to deliver an end-to-end solution to mobile operators who want to drive revenue-generating interactive video services, such as video communities and conferencing, participation TV, Mobile surveillance and monitoring, video contact centers and more. "Our partnership with RADVISION is an important component of our mobile strategy," said John Vitale, Director of Business Development and Strategic Partnerships for Clique Communications. "The new MVT client will be compatible with the nearly endless range of services that can be developed using the SCOPIA Interactive Video Platform. We believe this will usher in a new era of revenue-generating video services on pre-IMS and evolving IMS networks." RADVISION's Multimedia Terminal Framework allows application developers to focus on application development, hardware integration and user interaction rather than complex VoIP standards when developing Customer Premise Equipment (CPE) devices, such as IADs and WiFi Phones. This enables faster time-to-market. The framework is a complete solution, encompassing signaling, call control and media management. The SCOPIA Interactive Video Platform is an IMS-ready, carrier-grade video-enabled media server with flexible APIs for development and deployment of multiple interactive advanced multimedia services in converged networks. "This joint development effort is a real springboard for full IMS deployment, and complements our existing offerings in the mobile space," said Tsahi Levent-Levi, Product Manager for RADVISION Technology Business Unit. "RADVISION offers a complete line of technology products to develop IMS clients. Our cooperation with Clique positions us to provide client application level solutions using the jointly developed MVT and addresses the needs of customers like service providers with turn-key application solutions that go beyond our existing product line of enabling technology tools." The Mobile Video Telephony client is available now from RADVISION or Clique for customer demonstrations. Customization with carriers and OEM's of a SIP and H.264 compliant Video Telephony Client is planned for late Q4 2007. The new Mobile Video Telephony application will be showcased at the RADVISION Booth #537 at VON Fall 2007 in Boston October 29-November 1.
