TEL AVIV (April 08, 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 it has attained Gold Certified Partner status in the Microsoft Partner Program with a competency in ISV/Software Solutions for the third straight year, recognizing RADVISION’s expertise and impact in the technology marketplace. As a Gold Certified Partner, RADVISION has demonstrated expertise with Microsoft technologies and proven ability to meet customers’ needs. Microsoft Gold Certified Partners receive a rich set of benefits, including access, training and support, giving them a competitive advantage in the channel.

RADVISION recently introduced its SCOPIA Microsoft Office Communications Server (OCS) 2007 Connector providing advanced video conferencing system interoperability to Microsoft Office Communications Server 2007. The SCOPIA Connector enhances the Microsoft solution providing the capability for Office Communicator users to participate in conferences with standards-based video conferencing systems and devices. The SCOPIA Connector is a simple-to-use, highly flexible tool allowing OCS 2007 users to join a meeting hosted on the SCOPIA Conferencing Platform. With it, Office Communicator desktop users have full interoperability with video conferencing room systems including the latest HD (High Definition) endpoints with continuous presence multipoint video.

“RADVISION has a significant history of support of Microsoft technologies. Our unique expertise in creating solutions enhancing Microsoft’s Real Time Communications and Unified Communications initiatives has been recognized with the attainment of Microsoft Gold Certified Partnership status for the third straight year,” said Zeev Bikowsky, General Manager Networking Business Unit for RADVISION. “The benefits provided through our Gold Certified Partner status will allow us to continue to enhance the offerings that we provide for customers.”

“Customers are looking for partner companies that can bridge the gap between their business demands and technology capabilities,” said Allison Watson, vice president of the Worldwide Partner Sales and Marketing Group at Microsoft Corp. “They need to trust in a company that can act as an expert adviser for their long-term strategic technology plans. Microsoft Gold Certified Partners, which have certified expertise and direct training and support from Microsoft, can build a positive customer experience with our technologies. Today, Microsoft recognizes RADVISION as a Gold Certified Partner for demonstrating its expertise providing customer satisfaction using Microsoft products and technology.”

As one of the requirements for attaining Gold Certified Partner status, RADVISION had to declare a Microsoft Competency. Microsoft Competencies are designed to help differentiate a partner’s capabilities with specific Microsoft technologies to customers looking for a particular type of solution. Each competency has a unique set of requirements and benefits, formulated to accurately represent the specific skills and services that partners bring to the technology industry.

The ISV/Software Solutions Competency recognizes the skill and focus that partners bring to a particular solution set. Microsoft Gold Certified Partners that have obtained this competency have a successful record of developing and marketing packed software based on Microsoft technologies.

“Solutions competencies are an important way for Microsoft to better enable independent software vendors (ISVs) to meet customer needs,” said Sanjay Parthasarathy, corporate vice president of the Developer & Platform Evangelism Group at Microsoft. “They allow ISVs to keep and win customers through their deep knowledge of solutions-based Microsoft platform technologies. Microsoft has a long history of working closely with ISV partners to help them deliver compelling solutions and applications to our mutual customers, and the Microsoft Competencies are an important step in continuing to enhance vital relationships with ISVs worldwide.”

The Microsoft Partner Program was launched in October 2003 and represents Microsoft’s ongoing commitment to the success of partners worldwide. The program offers a single, integrated partnering framework that recognizes partner expertise, rewards the total impact that partners have in the technology marketplace, and delivers more value to help partners’ businesses be successful.
