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.
Regards,
daniel
