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.

Hello,
What is strange is that with Libpri 1.4.10 and previous version, the PBX
does not drop the link. With 1.4.11 it dropped multiple times so I reverted
back. This suggests the underlying physical link and clocking is OK. This
PBX I believe drops the link as a recovery mechanism for some protocol
issue or PBX side timer expiry. However, I've looked through the Asterisk
logs and nothing seems obvious to me.
I'll upload the missing file again.
Kris.
