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)????

If the SIP server listens on the private IP address only then you have to force it to use the public IP explicitely because it does not know it.
You can use record_route_preset("200.24.99.131;lr");
