Dear All When I get INVITE (received in UDP), I send it to another proxy in TLS. For this purpose I have modified kamailio.cfg route section , please refer the lines in red. Just before sending in TLS, I modify the IP address in SDP, so that media packets will pass through RTP proxy running When INVITE is reached the next proxy, I see the IP address is changed . So far so good.
Next I am trying to modify the IP address in 200 OK to INVITE. However it is not taking effect.
I hope we need to modify in onreply_route function. Something is wrong here. I am receiving 200 OK for INVITE in TLS. Next I am sending 200 OK for INVITE to endpoints using UDP. Not sure if onreply_route is being executed or not. Can somebody give me pointer whats wrong here.
*# Sample onreply route 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])") { force_rtp_proxy("r"); } if (isbflagset(FLB_NATB)) { fix_nated_contact(); } #!endif } *
* # Main SIP request routing logic # - processing of any incoming SIP request starts with this route route {
# per request initial checks route(REQINIT); setflag(FLT_NATS); # NAT detection route(NAT);
if(is_method("PUBLISH")) { loose_route(); t_relay(); exit; }
if(is_method("REGISTER")) { t_relay_to("tls:115.114.48.75:443"); exit(); }
if(is_method("INVITE|BYE|CANCEL|SUBSCRIBE|REFER|NOTIFY")) { xdbg("incoming request\n");
route(RTPPROXY); t_relay_to("tls:115.114.48.75:443"); exit(); }
