The code is not tested and might be broken. Parse the setup request
of a MO call, create a new "call" with a MNCC leg and then issue the
call to create a RTP socket. Once this has been done, release the call
as the code to open a second leg has not been written yet.
In case the MNCC server is crashing we need to release all calls,
use the event emitted by the MNCC connection and iterate over all
calls and call the release function.
Right now a call has two legs, the initial one and the remote. In
general this will allow a SIP to SIP, SIP to MNCC and MNCC to MNCC
structure in the future.
