SAN MATEO, California and READING, England, October 8 /PRNewswire/ --

Avistar Communications Corporation (Nasdaq: AVSR), a video collaboration
platform provider, today announced that Beyondis, a Reading, U.K.-based
distributor of Voice over IP and videoconferencing products, will offer
Avistar's patent protected C3 desktop technology to its resellers throughout
the U.K. This move enables Beyondis resellers to offer a deeper product line
to their customers, who have been requesting desktop videoconferencing as a
way to enhance their communications abilities among their employees.

Darren Innes, General Manager, Worldwide Sales, Avistar, said, "Avistar
desktop videoconferencing increases the 'stickiness' that resellers want in
their relationship with customers. It expands their ability to meet their
customers' needs, and it offers a whole new product area that is proven,
cost-effective and easy to use. They'll quickly find that it will help
them in existing customer installations as well as open new doors for them.

"Beyondis is known for its quality reseller support programs that are a
notch above the rest," he continued. "Having Avistar in its product portfolio
sweetens Beyondis' pot a bit more, and enables Avistar to have more feet on
the street representing our product line."

Andy Aikman, Technical Director, Beyondis, said, "Working with Avistar is
a logical extension of what we do and complements our product line. More and
more, customers want the convenience of videoconferencing without having to
schedule a room. With Avistar, they can have videoconferencing from their
home, desktop or hotel room -- essentially anywhere they have their laptop.
We expect that Avistar desktop videoconferencing will be a product initially
ordered by management, and then as they use it, they'll want to see it
accepted as a company-wide communications tool. We are thrilled to have
Avistar help us move our customers in that direction."
