RADVISION INTRODUCES VIAIP MULTI-SERVICE PLATFORM TO THEASIAN-PACIFIC MARKET AT TELECOM ASIA 2000 IN HONG KONG.

RADVision (Nasdaq: RVSN), has introduced its chassis-based viaIP multi-service platform to the Asian-Pacific market. The viaIP platform is being showcased at Telecom Asia 2000 in Hong Kong, a leading telecom conference targeting service providers, next generation telcos, and large enterprises from December 4-9. RADVision's viaIP all-in-one solution integrates multimedia gateways, multipoint conferencing, data collaboration, and gatekeeper intelligence into a single, standards-based platform. This cost-effective, Voice and Video over IP (V2oIP solution provides the scalability and proven interoperability needed for deploying IP-centric voice, video, and data services on large-scale IP communication networks.

"The Asian-Pacific market is experiencing a significant growth in large-scale video and voice over IP networks, especially in countries such as China, Taiwan, and Korea," said Dan Hochberg, Manager of RADVision Hong Kong, a RADVision subsidiary established earlier this year to provide sales and marketing support for the growing needs of the expanding Asian market. "RADVision's viaIP sets a whole new price/performance standard for high-capacity, IP-centric multipoint/gateway platforms. It supports the greatest number of concurrent users, conferences, and participants, and is simply the most cost-effective, flexible, user-friendly solution available today."

RADVision is presently introducing the viaIP at major events and road shows around the world. Following its initial U.S. introduction at ISPCON and the Asian-Pacific showcase at Telecom Asia, RADVision will present the viaIP platform throughout Europe, January 15-18, 2001, at its European Road Show in London, Paris, and Munich.

Scheduled to begin shipping in Q1/2001, the viaIP-400 is the first version of the viaIP platform to be introduced. It is a 4-slot Compact PCI (cPCI) chassis that supports hot-swappable, mix-and-match functionality. This highly configurable and scaleable design supports MCU cards for multipoint V2oIP conferencing functionality for 30, 60, and 100 conferencing ports per card and high performance Windows NT application server cards for running Data Collaboration Server (DCS) and Enhanced Communication Server (ECS) applications. DCS provides T.120 data sharing capabilities. ECS provides advanced gatekeeper functionality for managing H.323 network resources, implementing policies, and call control for real-time voice and video traffic. Multimedia Gateway cards with two PRI interfaces per card for translation between H.320 and H.323 will be introduced Q2/2001.
