I forgot to say that the received field is now present because I've changed the
route[NATDETECT] in the default configuration as
route[NATDETECT] {
#!ifdef WITH_NAT
force_rport();
-->>> if (nat_uac_test("19") || proto != UDP) {
if (is_method("REGISTER")) {
fix_nated_register();
} else {
fix_nated_contact();
}
setflag(FLT_NATS);
}
#!endif
return;
