[OpenSIPS-Users] dialog and accounting problem

[Denis Putyato]

Hello Bogdan

I have a lot of calls through Opensips. I found such call accidentally by looking another problem calls which has expired dialogs.
I will try to use debug 4 but I want pay your attention to fourth xlog. This xlog appear only when condition if (!$DLG_status == NULL) is true.
I see this xlog in log file, so Opensips as I understand, matched BYE to the dialog.

Hi Denis,

Indeed, the SIP capture looks like opensips is not matching the received 
BYE to the dialog....This is why the timeout is fired. But is strange, I 
do no see any obvious reason for the the matching to fail...

If you can reproduce this case, could you enable full debug in opensips 
(debug=4) in order to get more info regarding the BYE 
processing...Assuming that what you say is true - you get all 4 xlogs 
for the BYE.

Regards,
Bogdan
