Hi all, I have a user behind NAT with address : sip:userA@192.168.10.210:42276. When user send REGISTER, the proxy checks if user is behind NAT. If it is, proxy makes:
fix_nated_register(); force_rport(); setbflag(6).
When I check what kind of address proxy has saved on LOCATION database, I see at Contact column: sip:userA@IP_NAT:42276. So proxy mantains the same Port of the user and doesn't save the NAT's IP:PORT pair. Why? In this way, in fact, proxy is not able to keep connection alive.
