RADVISION Enables Alcatel-Lucent OmniTouch My Teamwork Conferencing and Collaboration Solution with SCOPIA® HD Multipoint Video Conferencing Capability

TEL AVIV (March 17, 2008) –

RADVISION® Ltd. (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 RADVISION and Alcatel-Lucent (Euronext Paris and NYSE: ALU) have teamed up to deliver multipoint video conferencing on top of the Alcatel-Lucent OmniTouch My Teamwork conferencing and collaboration application. Alcatel-Lucent’s enterprise collaboration customers can now benefit from RADVISION’s leading SCOPIA video conferencing platform.

OmniTouch My Teamwork, part of Alcatel-Lucent’s Unified Communications offering, delivers conferencing and collaboration capabilities across any network, from any location within or outside the business to support a dynamic enterprise environment–enabling workers to stay in touch from wherever they are at any time from any device. Businesses benefit from a flexible, software and standards-based platform for easy integration into business processes with carrier-grade scalability to accommodate growth. The full feature set with presence-based calling, ad hoc, reservationless, and scheduled audio and web conferencing, secure IM and integrated peer-to-peer video empowers employees with single-click access to a range of communication media so they can choose the best method given the task to perform their jobs effectively.

The SCOPIA video conferencing platform is a complete multipoint video communications solution that delivers a very cost-effective, high quality video experience. SCOPIA’s advanced media processing capabilities allow mixed conferences of HD (High Definition) video systems, standard definition end points, and video from desktops in the same call while preserving their native resolution and without requiring all participants to downgrade to their common capabilities. With the SCOPIA multipoint conferencing unit’s optimized capacity, users receive maximum value for their investment based on the video application they use – for example, in cases where HD is not fully utilized, the number of available ports for standard definition and desktop systems increases resulting in a reduced cost per port.

Additional benefits of the SCOPIA conferencing platform include:

* Connectivity to H.323, SIP, ISDN, and 3G video conferencing systems providing support for existing and future conferencing investments.
* Full transcoding and media processing between various audio and video formats from 3G to HD video allowing each participant to utilize the highest quality available to them.
* A highly collaborative video experience where through HD Continuous Presence, multiple participants can be seen simultaneously.
* Efficient bandwidth utilization where the connection rate remains constant regardless of the number of participants viewed.

“Combining RADVISION’s SCOPIA video capabilities with OmniTouch My Teamwork provides us with key enhancements to our product portfolio,” said Eric Penisson, vice president of Alcatel-Lucent, enterprise products. “The addition of SCOPIA positions us to increase our market penetration in the Unified Communications arena.”

“Extending the Alcatel-Lucent Unified Communications solution with the SCOPIA conferencing platform provides a very advanced and affordable video conferencing solution – where users of HD, standard definition, and desktop systems can all communicate,” said Zeev Bikowsky, General Manager Networking Business Unit for RADVISION. “Our unique method of advanced media processing provides great performance with affordable prices.”

The joint solution will be on display at the Alcatel-Lucent booth #711 at VoiceCon in Orlando March 17-20, 2008.
