[OpenSIPS-Users] dialog and accounting problem

[Bogdan-Andrei Iancu]

Hi Denis,

I agree with you on the 4th xlog - it should be printed only if the BYE 
matched the dialog - of course, if you identified the xlog sequence 
correctly :)

If the BYE matched the dialog, then the dialog should be terminated and 
no timeout.

What I can think of is that the BYE is not considered by opensips - do 
you see any errors in logs related to the BYE processing ?

Regards,
Bogdan
