ZIPDX ADVANCED CONFERENCING SERVICE SUPPORTS NEXT-GENERATION CONFERENCE PHONES FEATURING HD VOICE

ZipDX Leverages Wideband Audio to Maximize HD Voice Technology on Polycom’s New SoundStation IP 6000 and 7000 Conference Phones

LOS GATOS, CALIF. - April 8, 2008 - ZipDX, the only audio conferencing service offering standards-based wideband audio, today announced interoperability and full support for Polycom’s SoundStation® IP 6000 and SoundStation IP 7000 with Polycom HD VoiceTM technology. Polycom, the world’s leading provider of unified collaborative communications solutions, launched the breakthrough conference phones this week.

ZipDX recently completed beta testing among small and mid-sized enterprise customers who used the service with the SoundStation IP 6000 and IP 7000 conference phones.

Merit Games has been a ZipDX customer since October 2007 and participated in the beta program. “I never realized how valuable wideband audio was until I was able to experience it on my Polycom phone through ZipDX,” said Michael Maas, CEO of Merit Games. “With HD Voice, there’s less repetition and fewer misunderstandings. I’ve found our calls to be more productive overall. In addition, my team really appreciates a number of other ZipDX features that we haven’t seen with other services. Excuses about misplacing codes and losing track of time are gone; our conferences start promptly.”

The ZipDX system can work with the IP 6000 and IP 7000 in conjunction with an IP-PBX, or in a “ZipDX stand-alone” mode for those businesses that have not yet transitioned to VoIP, but want the benefits and outstanding user experience of high-performance voice conferencing.

ZipDX designed its Conferencing 2.0 audio collaboration service to maximize the capabilities of Polycom’s phones and incorporate additional features to enhance usability and productivity for Polycom customers, including a call dashboard on the conference phone display area.

“SoundStation IP 6000 and 7000 models set a new bar for conference phone performance,” said Chalan Aras, vice president of marketing for Polycom’s voice communications solutions division. “The ZipDX service is the perfect complement to these devices. Conference calls conducted using ZipDX in combination with our next-generation conference phones and existing HD Voice desktop phones deliver an unmatched user experience that leverages the wideband audio performance of Polycom HD Voice for astounding clarity and recognition.”

About Wideband Audio

Wideband audio encodes twice as much speech information as traditional, or narrowband, audio. Wideband-audio phones capture both the deeper lows and higher frequencies of the human voice to deliver crystal clear sound quality. It is an invaluable tool for conferencing, where it is often a challenge to identify speakers with similar voices, understand accented speakers, overcome background noises and hear faint talkers.
