Abstract (en)
[origin: WO2009153176A1] In a method for determining active communication sessions, a request to determine active communication sessions is received. Queries as to whether communication sessions are currently active are sent to at least two communication session servers. The respective query answers that indicate one or more active communication sessions being controlled by the respective communication server are received. A first answer that indicates one or more active communication sessions being controlled by the at least two respective communication servers is sent. A communication session information server executes the method.
