/**

* Class for mobile originated MCE sessions.

*

* CMceOutSession represents outgoing invitation to remote terminal to join in a session.

*

* The characteristics of the session are defined by user of this class by attaching

* media streams into the session. Theses charactereistics are turned by MCE server into SDP

* and attached into sent invitation request.

*

* After the session has been succesfylly established, it can be later updated and

* must be finally terminated.

*

* If for any reason instance of this class is deleted while in established state,

* session is automatically terminated by MCE server.
