Summary: Q931 not sending RELEASE after getting DISCONNECT
Description:
Several times per day, I'm getting Disconnection Cause Codes 102's
(recovery on timer expiry) which BT tell me are the result of Asterisk not
sending
a RELEASE in response to a DISCONNECT.
I'm seeing a handfuls of these in 'bursts' on a system making/taking
around 1500 calls per day and while the net result is that we loose a
channel for 30 seconds while it times out, these instances are visible to
the boss and I'm getting grief over them :-(
I've turned on pri debug and attached an example of one of these calls and
it does seem that BT are correct - there's no response sent to the
DISCONNECT
message and the exchange sends a RELEASE with a cause code of 102 some 30
seconds after the original DISCONNECT was sent.
Curiously the logger always seems to output the same strangeness for the
Cause data in these instances like so:-

If it's any help, here's the timing of the instances this week (grep
'cause 102' /var/log/asterisk/full.X) so you can see the clumping:
