Hi Nick,
So, your opensips should do the NAT traversal for the signaling
(fix_nated_contact() stuff), but it should not do anything in regards to
media (rtpproxy) if caller and callee are behind the same NAT - how to
test that ? after lookup(location), when you know the destination IP of
the callee, you can simply check if SRC IP of the call is the same with
the destination IP - if so, it means caller and callee are behind the
same NAT.

Hello
I checked it. It don't to go to the route[nat_fixups].
But My UACs both behind the same NAT.
How to check why not go to the route[nat_fixups]??
Thanks
Nick

It will change it if fired. Make sure that you get to
"route[nat_fixups]" for the call. And for testing, try removing the
flags" (isflagset(5) || isbflagset(6))" etc... xlog("Why me god:
$ru\n") always seems to have mercy on our souls. ;)
Nick.
