[OpenSER-Users] Mediaproxy listening but handling zero bytes of audio - sr-users

5 Feb 2008


      Hi,
Im trying to test mediaproxy for the first time, I am forcing all traffic through mediaproxy in the openser.cfg (there's
nothing wrong with that in principal is there?). I have one SIP handset hanging directly off OpenSER and another
connected to Asterisk which has a channel configured to OpenSER. I can get the call answered but there is audio
only in one direction and even more strangely I see that mediaproxy has not handled any data at all in the audio stream.
This is what I see from mediaproxy:

This "0/0/0 packets, 0/0/0 bytes (caller/called/relayed)" being the part that I dont understand, well it proves its not handling the audio
stream, but other than put a use_media_proxy command in the openser route there isnt anything else I can do to get the data stream
to route via media proxy is there?
My openser route is very simple:
route{
if (!mf_process_maxfwd_header("15")) {
        sl_send_reply("483","Too Many Hops");
        exit;
    };
if (msg:len >=  max_len ) {
        sl_send_reply("513", "Message too big");
        exit;
    };
if (method=="OPTIONS") {
        exit;
    };
if (method=="REGISTER") {
        record_route();
                if (!save("location")) {
                sl_reply_error();
        };
        exit;
    };
if (loose_route()) {
        append_hf("P-hint: rr-enforced\r\n");
        if(is_method("BYE"))
        { # log it all the time
            acc_rad_request("200 ok");
            acc_log_request("200 ok");
            end_media_session();
        }
        route(1);
    };
if(is_method("INVITE") && !has_totag())
    {   # set the acc flags
        record_route();
        use_media_proxy();
        setflag(1);
#        setflag(2);
        $avp(s:can_uri) = $ru;
    };
if (!uri==myself) {
        append_hf("P-hint: outbound\r\n");
        route(1);
    };
if (uri==myself) {
if (!lookup("location")) {
            # log to acc as missed call
            acc_rad_request("404 Not Found");
            acc_log_request("404 Not Found");
            sl_send_reply("404", "Not Found");
            exit;
            };
        append_hf("P-hint: usrloc applied\r\n");
    };
route(1);
}
# SECTION 5 - SECONDARY ROUTE BLOCKS
route[1] {
    if (!t_relay()) {
        sl_reply_error();
    };
    exit;
}
Anyone any ideas what might be going on or how I can investigate the issue further?
thanks for any help! Andy.
