Abstract
The method is executed by a call control server that establishes a media session for sending and receiving media data between a calling terminal and a called terminal. The method includes exchanging messages with calling terminal and called terminal for establishing the media session, generating a session information necessary for establishing the media session based on the messages exchanged with the calling terminal and/or the called terminal, monitoring a media information included in the messages, the media information containing a definition specifying a way of exchanging the media data, determining, based on the monitoring result, whether the media session has been established, and transferring the session information to at least one other call control server different from the call control server if the media session has been established.
