Microsoft to test new IM server - News - ZDNet "The new version of Live Communications Server will push the presence picture forward, said Dennis Karlinsky, lead product manager for Microsoft, with several new "federation" features that allow IM sessions and availability information to be used outside the corporate firewall.
Businesses maintain an "edge proxy server" to serve as a gateway to other Live Communications Server users, Karlinsky said. Companies can selectively share availability information with other businesses, helping to streamline communications and transactions.
"The main goal our customers have told us about is they want to be able to connect to customers and partners," Karlinsky said. "We want to provide the ability for two or more enterprises to connect in a secure way."
