Re: [SR-Users] Enforced TLS, still some packets are through UDP

Hi,

TLS work on TCP 5061 To view the header you can use $ hdr (HEADER_NAME).

Not much English, sorry.

Dear All I ma trying to have all SIP signalling through TLS. Using Kamailio 3.1.5.

In a typical setup, endpoints initiates call, messages reach Kamailio proxy, Kamailio proxy forwards these packets to main proxy.

In Kamailio.cfg, I have added below code.

route {

    # per request initial checks
    route(REQINIT);
    setflag(FLT_NATS);

    if(is_method("REGISTER"))
    {
            t_relay_to("tls:115.114.48.19:443");
            exit();
    }
    else
    {
            xlog("incoming request\n");

            route(WITHINDLG);
            route(RTPPROXY);
            t_on_reply("REPLY_ONE");
            t_on_failure("FAIL_ONE");
            t_relay_to("tls:115.114.48.19:443");
            exit();
    }

..............

I am finding most of the messages are getting transmitted in TLS. But few ACK and REFER / REFER response packets are still being transported in UDP.

Can somebody tell me whats the wrong I am doing here.

By any chance route(WITHINDLG); route(RTPPROXY);

before t_relay_to("tls:115.114.48.19:443");

can cause this ????

And one more doubt.., 115.114.48.19 I get in route header. How can I extract the value of route header, so that I do not have to hard-code

Many thanks in advance.
