Summary:                    [patch] LibPRI problem with restart of PBX processor
(Testing SVN 1688)
Description: 
Asterisk is connected to legacy Siemens PBX. PBX has dual CPU and switches
over active/passive processors at (or close to) 00:00.

During the switchover, the link stays up but the PBX sends SABME. Asterisk
should clear state to restart q921. A few seconds after the first call
comes in, we see the legacy PBX drops the link and tries to re-establish -
it normally does this after a protocol error (timer expiry etc).

I will try and reproduce with pri debugging enabled.

---------------------------------------------------------------------- 
The issue17360_v1.4.patch should fix the sequence error problem.  The last
trace was a big help.  Libpri was passing an event from Q.921 to Q.931
before Q.921 was finished processing the frame.  Q.931 immediately sent a
message in this intermediate state which put Q.921 in a bad state.
