Dear all,
I have a Kamailio with RTPoxy configured. The purpose is to pass the RTP from this server. When I make calls behind NAT the RTProxy seems to be engaged but in traces I don't see any RTP.
Is there anything wrong with the idea or I'm missing something in the configuration ?
Thank you Alex

That would be difficult to know without seeing your configuration.
Dear Alex,
The configuration is the default with WITH_NAT defined. I have some extra logs (xlog("RTPPROXY started..")) enabled in the RTPPROXY route in order to understand if it is engaged or not.
When I make calls behind NAT the RTPPROXY is engaged but I don't see any RTP in traces.
Do you have any idea on how can I keep the RTP?
Thanks Alex Pappas

Dear all,
I see in my logs that when the call enters the route :
# Caller NAT detection route route[NAT] { #!ifdef WITH_NAT xlog("alx --- ROUTE NAT , we have nat ---"); force_rport(); *if (nat_uac_test("8")) {* if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(FLT_NATS); xlog("alx --- ROUTE NAT , set flag FLT_NATS ---"); } #!endif return; }
I get the following error:
nathelper [nhelpr_funcs.c:195]: *message body has length zero* nathelper [nathelper.c:1184]: *cannot extract body from msg!*
From traces i see that only in the SDP I have an IP which is not public but
even with that I cannot engage the RTPPROXY.
My Kamailio version is 3.1.3 and the config file is plain , from installation.
Any ideas?
Thank you Alex

8 - SDP is searched for occurrence of RFC1918 addresses
So I gues you call nat_uac_test("8") for a request which does not have a body at all. You could use has_body from textops module to extend the check, e.g:
if (has_body("application/sdp") && nat_uac_test("8")) { ...
