Summary:                    Failure of resetting of a PRI B-Channel causes
deadlock in process
Description: 
By default, once every hour, the Asterisk system resets the channels of a
PRI. This workflow is based on "reset the first channel"; when the reset
gets acknowledged "let's reset the next channel" until all channels are
done. This works fine if all channels get acknowledged, but when an
acknowledgment isn't received, the whole system is deadlocked for that
PRI.

This is the change in /etc/asterisk/zapata.conf:

 ;
 ; PRI resetinterval: sets the time in seconds between restart of unused
 ; channels, defaults to 3600; minimum 60 seconds.  Some PBXs don't like
 ; channel restarts. so set the interval to a very long interval e.g.
100000000
 ; or 'never' to disable *entirely*.
+; PRI resettimeout: sets the time Asterisk will wait for an
acknowledgement 
+; on a restart of an unused channel, defaults to 3.
 ;
 ;resetinterval = 3600
+;resettimeout = 3
 ;
 ;
