I added these lines to my REGISTER section


Code:
if (nat_uac_test("31")) {
if (method=="REGISTER") {
fix_nated_register();
} else {
fix_nated_contact();
};

now it looks like this:

Code:

if (is_method("REGISTER"))
{
# authenticate the REGISTER requests (uncomment to enable auth)
if (!www_authorize("", "subscriber"))
{
www_challenge("", "0");
exit;
}

if (!save("location"))
sl_reply_error();

exit;
if (nat_uac_test("31")) {
if (method=="REGISTER") {
fix_nated_register();
} else {
fix_nated_contact();
};
};


}


but still have one way audio, the reason is that for the ext registered in my house KAMAILIO does not change the private ip for the public one, however for the ext registered from my office it does it.

also, I saw these messages in the var/log/messages file:

I tried restarting kamailio and rtpproxy but with no luck.
Has anyone been able to config kamailio 1.4 with rtpproxy?
thank you all in advance
Fabian

Subject: [Kamailio-Users] kamailio and rtpproxy-no audio

hello

I am trying to use rtpproxy and kamailio. Below please find my kamailio.cfg file.
But this is what is happening:
1- ext 101[IP 76.109.183.2] is able to send audio to kamailio's IP [65.111.185.187]but it does not reach ext 100 IP [76.109.15.75].
2- ext 100 does not send RTP at all.
3- I still see the private IPs in the SDPs of both exts.

I am aattaching a wireshark capture
Thank you in advance

Fabian
