Summary:                    Immediately releases channel after a DISCONNECT with
In-band audio
Description: 
When the network side sends a DISCONNECT message, libpri sends a RELEASE
and enters Release Request state.
While this is a valid behavior at all cases, it would be nice to be able
to hear the in-band disconnection message, where found.

However, before sending a RELEASE, the B-channel is opened and the audio
is played by Asterisk for a short moment.
This is quite annoying since if the audio is a message and not a tone, it
is chopped, resulting in user confusion.

Attached is a patch that ignores the DISCONNECT when it is accompanied by
inband audio. This is fine and a recommended behavior according to the spec
(Q.931, 5.3.4.1) since the network will start timer T306 (network
dependent) and send a RELEASE after that expires.
