Hi, My Kamailio server listens on multiple IPs - say IP1, IP2. If a request arrives on one IP, Kamailio uses the same IP as the source address when forwarding, which is good. But is there any way a UA could generate a request to IP1 that gets forwarded by Kamailio with source address IP2 ? The reason I ask is because Asterisk is setup to trust all calls arriving from IP2 but not IP1.
Thanks Ben

Yes, this is the function of force_send_socket() and/or $fs.

Thanks Alex. I didn't actually want to change the socket in my kamailio script. Just checking that there is no way the SIP message itself can specify which source IP is used when forwarding.

Maybe, if I understand you correctly, the 'advertised_address' and/or 'advertised_port' settings are the thing for you?

No, these parameters are not used for selection of socket, not even for routing. They are the values to be used to build Via headers, instead of using the values from sending socket.
mhomed helps also in selection of the right outgoing socket, when the route to destination is possible only from specific sockets.
Cheers, Daniel
