[OpenSIPS-Users] dialog and accounting problem

[Bogdan-Andrei Iancu]

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
