I think this has been discussed once before, and perhaps the best/only way would be to use and on-bridge script to compare the addresses. However, when you call uuid_media and freeswitch sends the reinvite, I bet it using the resolved public IP address of the phones rather than the internal ones. If there's a way to do it, it'll be based on that. Running a script to send the reinvite pointing to the internal addresses and port numbers SDP addresses. Assuming the SDP hasn't been modified.

Thank you guys for all your hints.
ICE & TURN are quite new protocols invented to fix all issues that STUN leave not fixed, such as double NAT. They try to discover client network topology.
I think best solution is marking each phone on the same site with a flag and using bypass media.
Thanks again.
