[OpenSIPS-Devel] Using dialog module functions from LOCAL_ROUTE

[Bogdan-Andrei Iancu]

yes, it is NULL as in LOCAL ROUTE there is no dialog information stored 
- this is by design (not intended to have dialog context in LOCAL ROUTE. 
This information can be pushed from the dialog module as the dialog 
module is the one triggering the BYE request...

...give a bit to review some code.....

Regards,
Bogdan
