Re: [SR-Users] Kamailio cfg file doubt

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.

THe onreply_route {} is executed for every response. If you want to trigger your own reply route, like your onreply_route[REPLY_ONE] {} you have to do it with the TM module funcition t_on_reply().

/O

# 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();
    }
