-------------------------

Hi Richard,

Thank you very much for your response, I added those line to chan_dahdi.conf as bellow:

K =  1
pritimer = K,1

But unfortunately i'm still getting this error: Channel 0/1, span 1 got hangup, cause 102

Please note that all the incoming calls that are directed to other SIP trunks are working fine, except this trunk which is cisco unified communications call manager. 

Regards

> 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:-
