Avistar and MVC Mobile Video Communications Team to Deliver Desktop Videoconferencing Solutions in Germany

Avistar Communications Corporation (Nasdaq: AVSR), a leading provider of unified visual communications solutions, has signed an agreement with MVC Mobile Video Communications GmbH of Frankfurt to sell Avistar's C3 desktop technology in Germany. The partnership agreement enables German companies and their employees to enjoy the benefits of desktop video conferencing conveniently and easily wherever they may be.

According to Simon Moss, CEO of Avistar, "Germany is the world's third largest economy and a prime market for videoconferencing solutions, particularly because it has such a strong commitment to 'green' initiatives. Desktop videoconferencing reduces the need for business travel, helping companies reduce their carbon footprint. As Germany's leading provider of video, audio and data conferencing solutions, MVC is well-equipped to represent Avistar and deliver our award-winning C3 technology solutions to customers."

Dr. Sven Damberger, CEO of MVC, said, "Avistar's C3 technology fills an important niche in our unified communications portfolio by bringing standards-based, interoperable videoconferencing to the desktop. It's a logical extension for our customer base, which is more frequently asking for ways to bring the benefits of room-size videoconferencing to users at their desks so they can cut back on travel costs and reduce their environmental impact."
