SAN MATEO, Calif., Jan. 17 /PRNewswire-FirstCall/ -- Avistar Communications Corporation , has announced that Colgate-Palmolive Company, a multinational consumer products company, will deploy its desktop videoconferencing technology integrated with Lotus Sametime. Beginning with an initial installation this month, Colgate-Palmolive's aim is to benefit from the most innovative and effective combination of collaboration tools available for the corporate environment. Colgate-Palmolive recognizes the value that Avistar desktop videoconferencing adds to unified communications, by improving communication, fostering collaboration, and reducing travel expenditures, with their associated carbon emissions.

Colgate-Palmolive has opted for Avistar's hosted service, enabling infrastructure management and technical support to be off-loaded, yet offering full product performance and reporting. Following a successful rollout, the company expects to extend desktop videoconferencing more broadly later in 2008 and into 2009, with the potential to include thousands of users.

"Our objectives in adding desktop videoconferencing to our Sametime installation are to enhance collaboration across geographic boundaries in order to deliver new products more quickly, gain the value of face-to-face communications both internally and with suppliers, and to reduce travel expense and its impact on our environment," said Jack Haber, Vice President of Corporate eBusiness at Colgate-Palmolive.

"Avistar effectively integrates with Lotus Sametime to bring desktop videoconferencing to any number of uses across the enterprise," said Darren Innes, Avistar's general manager for worldwide direct and channel sales.
