Summary:                    Asterisk does not end call properly and stops
reacting to following SETUP messages
Description: 
Using libpri 1.4.11.4. About once in a week or two Asterisk stops reacting
to SETUP messages with a certain call reference number. Message is
completely ignored and it does not reply until Asterisk is restarted. As
the PBX on the other side of ISDN reuses this call reference often, it
almost completely disables making any call. I am adding the full log with
pri intense debug. Call has reference number 2304, you can easily see the
situation:

grep "reference 2304" log

In the last working call asterisk didn't reply to RELEASE message. Since
this moment all messages with this reference number were ignored. It could
be as well libpri issue but chan_dahdi seems to me more appropriate.

Issues with ISDN calls changing B channels during call negotiations.

The handling of the PROCEEDING message was not using the correct call
structure if the B channel was changed.  (The same for PROGRESS.) The call
was also not hungup if the new B channel is not provisioned or is busy.

* Made all call connection messages (SETUP_ACKNOWLEDGE, PROCEEDING,
PROGRESS, ALERTING, CONNECT, CONNECT_ACKNOWLEDGE) ensure that they are
using the correct structure and B channel.  If there is any problem with
the operations then the call is now hungup with an appropriate cause code.

* Made miscellaneous messages (INFORMATION, FACILITY, NOTIFY) find the
correct structure by looking for the call and not using the channel ID.
NOTIFY is an exception with versions of libpri before v1.4.11 because a
call pointer is not available for Asterisk to use.

* Made all hangup messages (DISCONNECT, RELEASE, RELEASE_COMPLETE) find
the correct structure by looking for the call and not using the channel
ID.
