TANDBERG Teams with WebEx to Expand Collaborative Conferencing Offering

TANDBERG Extends Web Communications Capabilities with ACE Vision

NEW YORK AND SAN JOSE Calif., April 28, 2003 -- TANDBERG, a global provider of collaborative communication solutions, and web communications leader WebEx Communication, Inc. (Nasdaq: WEBX), have developed a comprehensive service for data, voice and video communication that allows enterprise customers to combine the capabilities of TANDBERG's videoconferencing platform and WebEx's MediaTone communications network. The new service enables customers to participate in meetings by video, audio or web conferencing service and allows TANDBERG to better serve the rapidly growing demand for highly integrated collaborative communication services.

"The combination of TANDBERG and WebEx creates a complete virtual conference room environment, extending the reach of both web and video conferences," said David Alexander, industry analyst and research manager of Frost & Sullivan. "This is a step in the right direction for both vendors, enabling them to leverage TANDBERG's expertise in videoconferencing and WebEx's talent in the web conferencing marketplace."

This is an important step in fulfilling the promise of TANDBERG's Architecture for the Collaborative-Communications Enterprise (ACE). ACE is a framework for unifying the many essential components required to build an integrated voice, video and data solution. ACE allows TANDBERG users to connect to the WebEx MediaTone Network, a global network specifically designed for high-speed web communications, to add WebEx capabilities to traditional videoconferences or include PC-based attendees in the meeting. WebEx meetings do not require any specialized hardware or software, just a browser and Internet connection.

At the core of ACE is the TANDBERG Management Suite (TMS) and Scheduler -- the common software platform that manages components and services from multiple vendors in a single system. To schedule a conference, the administrator using TMS, or the end user using Scheduler, simply selects the WebEx option when scheduling a meeting. The confirmation e-mail includes information for audio and video calls plus a link that brings participants into the meeting via the Internet.

"WebEx is the only company to design, develop and deploy a global, switch-based network specifically developed for interactive and live Web communications," said Andrew Miller, vice chairman and CEO at TANDBERG. "At TANDBERG, it is clear to us that the Internet is a critical component to any collaborative communications solution that attempts to integrate voice, video and data for the enterprise. To deliver on our unique and powerful ACE vision, our teaming with WebEx, the industry leader in Web communication services, will provide our customers a comprehensive solution."

"TANDBERG is the technology leader in videoconferencing," said Subrah Iyar, CEO of WebEx Communications. "By combining TANDBERG's videoconferencing platform and the WebEx MediaTone Network, customers will have access to the most innovative and easy-to-use communication services on the market."

WebEx provides web communications services to corporations, technology companies and telecommunications providers worldwide. WebEx's services enable end-users to share presentations, documents, applications, voice, and video spontaneously with anyone, anywhere, using Windows, Macintosh or Solaris systems, all through the browser. All of WebEx’s services are built on the MediaTone communications platform and delivered through the WebEx MediaTone Network, the only global network designed and deployed for high-speed Web communications.

At every level of an organization, TANDBERG collaborative solutions allow people to connect and share information faster and more efficiently. TANDBERG offers a high-performance video system for every video need and room size. In addition, easy-to-use TANDBERG software schedules and manages video, audio and web conferences. All TANDBERG products support the ACE vision of open standards and interoperability with best-of-breed solutions. Corporations, government agencies, healthcare service providers and educational institutions maximize productivity with collaborative solutions from TANDBERG.


TMS and Scheduler support for the WebEx MediaTone Network will be available in Q2.
