bug: sometime lrc asks the daemon to send a message with an invalid
     call id.

fix: lrc checks if the call is still in the calls list and if the
     call is running.

bug: lrc send messages trough sip channel when the call is in status
     other than in progress or on hold.

fix: lrc checks the status, and decide wich way to send the message.
