Avistar Communications Corporation has hired Darren Innes as general

generating a new level of intensity in our sales and distribution efforts,
complementing our market leadership in intellectual property and licensing

Under his direction, I look forward to significant new business partnerships,
channel and direct sales growth in 2008."

in the unified communications revolution," said Innes. "I know from
experience the importance of effective communication across large and
dispersed organizations. Avistar's patented technology makes it possible for

naturally and accelerating the accomplishment of shared objectives. And while
the alternatives are hyping their promise, Avistar is proven at scale in real
installations."
