Hello, until this morning I haven't been able to modify any
configuration, what I did basically, is to use nat_uac_test("19") in
both places.
if (is_method("INVITE")) {
+ if(nat_uac_test("19")) {
- if(isbflagset(2)) {########## # behind a NAT
log("MIS: Forcing proxy within router 1")
force_rtp_proxy();
};
Watching the logs it seems that nat i detected properly during the
INVITE and the force_rtp_proxy is called for the outgoing call, but
rtpproxy gives back an answer that kamailio doesn't recognize.
I could't find any reference to this value neither.
