Hello,
I also tried rtpproxy_offer/rtpproxy_answer but no luck.
my rtpproxy is running..
rtpproxy -l 192.168.2.3 -l 127.0.0.1:7722 -u user
and kamailio on 192.168.2.3 asterisk on 192.168.2.23
all three in behind same nat 175.136.223.112.
and uac is behind another nat.
below is my wireshark INVITE and 200OK.
route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) {
unforce_rtp_proxy(); } else if (is_method("INVITE")){
rtpproxy_offer("rco","175.136.223.112"); xlog("offer"); } if
(!has_totag())
add_rr_param(";nat=yes"); #!endif
onreply_route[REPLY_ONE] {
xdbg("incoming reply\n");
#!ifdef WITH_NAT
if ((isflagset(FLT_NATS) || isbflagset(FLB_NATB))
&& status=~"(183)|(2[0-9][0-9])") {
rtpproxy_answer("rco","175.136.223.112");
xlog("answer");
}
if (isbflagset("6")) {
fix_nated_contact();
}
#!endif
