Yes, thanks, obviously my config is not for every NAT case XD
Anyway I'll try to add in a future a solution for that. I could test to if the
caller Contact and called Contact are "similar" private IP. Anyway this is
not 100% secure since we cannot know which netmask are they using, so we
cannot know if they are in fact in same LAN.
Any suggestion?

if (isbflagset(5)) { # Caller is behind NAT
if ( $dd == $si ) {
xlog("L_INFO", "Both users behind same NAT, so we dont use
RtpProxy\n"); resetbflag(6); # Unset NAT flag general.
}
}
if two sip UAs have same public ip address, it does not mean that they
would be behind the same nat. there may be another nat box behind the
first one. in fact, it is a very common case, when dsl modem includes
nat and a few ethernet ports and you connect a wlan ap to one of them.
