[Serusers] SER 0.8.14 + MEDIAPROXY: 2 UA BEHIND the same NAT : no sound - sr-users

21 Mar 2005

HI,

I have installed SER 0.8.14 + MEDIAPROXY : when I make a call with 2 UA on
different NAT, it's good.

But, when the UAs are behind the same NAT, there are no sound. The RTP
packets go to the MEDIAPROXY but NO SOUND.

Does someone know how to solve this problem???

Best Regards

Thats my conf :

    if (method=="REGISTER") {
            # Mark as NAT'ed
            if (client_nat_test("3")) {
                setflag(2);
                force_rport();
                fix_contact();
            };

            if (!www_authorize("sip.vivaction.net", "subscriber")) {
                www_challenge("sip.vivaction.net", "0");
                break;
            } else if (!check_to()) {
                sl_send_reply("403", "Username!=To not allowed");
                break;
            };

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

        break;
    };

    if (method == "BYE" || method == "CANCEL") {
        end_media_session();
    };

    if (loose_route()) {
        if (method=="INVITE" || method=="ACK") {
            use_media_proxy();
        };
        # end media session for BYE and CANCEL is done above
        # before entering the loose route. no need to call it here
        t_relay();
        break;
    };

    # Force subsequent messages to pass trough this proxy
    if (method == "INVITE") {
        record_route();
    };

    if (client_nat_test("3") && !search("^Record-Route:")) {
        # Mark as NAT'ed
        force_rport();
        fix_contact();
    };

    if (method=="INVITE") {
            t_on_reply("1");
    };

    if (is_uri_host_local()) {
        if (!lookup("location")) {
            sl_send_reply("404", "User not found");
            break;
        };
    };

    if (method=="INVITE" || method=="ACK") {
        use_media_proxy();
    };

    if (!t_relay()) {
        if (method=="INVITE" || method=="ACK") {
            end_media_session();
        };
        sl_reply_error();
    };
}

failure_route[1] {
    end_media_session();
}

onreply_route[1] {
 if (status=~"(183)|(2[0-9][0-9])") {
        if (client_nat_test("1")) {
            fix_contact();
        };
        use_media_proxy();
    };
}
