[OpenSIPS-Users] How to know that caller and callee talk from differente networks?

[Rodrigo Pimenta Carvalho]

Hi.


In my script OpenSIPS.cfg sometimes I do need to call "set_advertised_address" and sometimes I don't.


Basically, I want to call this function only for messages between caller and callee that is registered from different networks. Ex: caller is in the same network (LAN) as the sip proxy and the callee is somewhere on Internet.


So, how to know that, during a dialog, caller and callee are in 2 different networks?


When they are in different networks, I want to call set_advertised_address for SIP OK and SIP BYE messages.


Any hint will be very helpful!


Thanks a lot.
