[OpenSIPS-Devel] dialog module: dialog not cleaned up when BYE is sent

[Bogdan-Andrei Iancu]

Herman,

So after the BYE, what is the exact dialog state reported by MI cmd? 
(please post the output)

Also, is the dialog still present in the DB?

BTW, you do not have to do unset_dlg_profile() if negative reply is 
received - this will happen automatically as the dialog will be 
destroyed (theoretically :D)

Regards,
Bogdan
