[OpenSIPS-Users] Function set_advertised_address() seems to have wrong decision. Workaround?

[Bogdan-Andrei Iancu]

Hi Rodrigo,

The set_advertised_address() is not changing anything by itself, but 
setting (as the name says) what should be the IP when comes to 
advertising OpenSIPS in new headers like VIA or Record-Route - once 
again, when building and inserting such headers. This happens for 
requests, not for replies.

So, I do not understand your case with calling the function for a 200 OK 
:( .Do you have a trace at opensips level ?
