PLEASANTON, Calif. and BOSTON, Oct. 29, 2007 -- VON CONFERENCE & EXPO (booth 629) -- Polycom, Inc. (Nasdaq: PLCM), the world's leading provider of unified collaborative communications solutions, today announced the Polycom HDX platform was named the best high definition (HD) video conferencing solution by Wainhouse Research in a head-to-head comparison with competing systems from Tandberg and LifeSize. The Polycom HDX series received top marks in eight out of 10 categories, including video quality, audio quality, and multimedia performance, as well as HD and SD (standard definition) interoperability, camera quality and performance, user interface and content-sharing performance (H.239).

"In our comparative review of three industry-leading HD video conferencing endpoints, Wainhouse Research named the Polycom HDX platform as our number one choice," said Andrew W. Davis, managing partner, Wainhouse Research. "Our extensive, hands-on competitive analysis shows that the Polycom HDX series received top scores in 8 out of 10 evaluation categories. Besides great video quality, the HDX series provides outstanding, leading-edge audio performance and unparalleled multimedia capabilities."

Polycom HDX video conferencing systems are the only video conferencing endpoints on the market to deliver the value of UltimateHD(TM), which includes HD video, HD voice and simultaneous HD multimedia content-sharing capabilities.

"The Wainhouse Research evaluation reinforces what Polycom customers have already experienced: that Polycom HDX solutions are the best video conferencing choice across applications and use scenarios," said Joe Sigrist, senior vice president and general manager of video solutions at Polycom. "Polycom believes that delivering the best user experience is about more than just video resolution, it is also about voice quality, the ability to share content in HD, the user interface, camera performance and more. It is also about giving customers a complete integrated solution for HD video conferencing that makes the technology reliable and easy to deploy, manage and use."

Polycom has expanded the award-winning HDX line to now include the HDX 4000(TM) series, personal multimedia HD systems designed for executives, physicians and small groups; the HDX 8000(TM) series, for mid-range conference and meeting rooms; as well as the HDX 9000(TM) series, for large meeting rooms, classrooms and integrated custom-room environments. The HDX platform also powers the Polycom RealPresence(TM) Experience (RPX(TM)) HD immersive telepresence solutions and Polycom Telepresence Experience (TPX(TM)) HD telepresence solutions, providing seamless interoperability between telepresence solutions and video conferencing endpoints.

Polycom HDX systems also feature patent-pending Lost Packet Recovery technology to help ensure an outstanding video conferencing experience for voice, video and content, even on networks with considerable levels of IP packet loss. Lost Packet Recovery can improve the pervasiveness of video conferencing in an organization by ensuring the highest and most consistent quality for home office workers, field deployments, calls on "dirty networks" subject to frequent packet loss, and even calls over the public Internet.

The standards-based Polycom HDX line is part of the industry's only integrated and complete HD video collaboration portfolio, including HD video endpoints and systems, telepresence and immersive telepresence solutions, HD conferencing bridges, HD recording, streaming and playback systems (for both video and content), HD video content management, and integrated Polycom HD Voice endpoints.
