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.

  Prevent a CONNECT message from sending a CONNECT ACKNOWLEDGE in the
wrong state.

  Filter the processing of the CONNECT message to prevent libpri from
  sending a CONNECT ACKNOWLEDGE when the call is in an inappropriate
state.
  This can happen when we hang up an outgoing call after the other end has
  sent a CONNECT but before we have processed the CONNECT.
