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

[Bogdan-Andrei Iancu]

Herman,

The log you posted on the forum did not show any usage of loose_route() 
- if you look on the log, for ACK and BYE there is no mesage from "rr" 
or "dialog" module. Can you confirm this?

Regards,
Bogdan
