Laut Cisco geht es bei der Zusammenarbeit mit Microsoft zunächst um die Presence-Federation der Lösungen der beiden Anbieter. Das Problem:

“Currently, Cisco federates all the presence and availability information from its unified communications systems and publishes that data to Microsoft’s Office Communications Server (OCS), which can then push it to Microsoft clients. Microsoft doesn’t reciprocate. The companies are working on making the same kinds of information go from Microsoft’s software into Cisco’s, said [Rick] McConnell, who is vice president and general manager of Cisco’s Unified Communications Business Unit.”
