Summary:                    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 trace shows Asterisk sending the SABME's because it could not get a
response from the PBX.  Then T309 times out and drops the active calls. 
This behavior should happen under these circumstances because
communications failed for some reason.  DAHDI has indicated that it lost
layer 1 and the link went into alarm.  It did not come out of alarm until
after the calls were dropped.  When it came out of alarm communications
were able to resume.

Your other trace appears to have been accidentally deleted.
