I have a little problem, i need to force the UA (outside NAT with public IP address) to send the BYE messages to my Sip Server so I can account them in the acc table. I use record_route() to acomplish that but the thing is the Record-Route field in the message that an UA recieve, the IP address is the SIP SERVER LOCAL IP ADDRESS BEHIND NAT (Record-Route: <sip:5000022@192.168.0.2;ftag=192550680;lr=on>) which means, of course, that the message will not pass trough the SIP Server. How Could i force the server to write in the Record-Route field the valid IP address of my Sip Server (200.24.99.131)????
