[OpenSIPS-Users] Trouble getting mediaproxy to work (dialog module)

[Dan Hislop]

Hopefully this is better:  (it looks ok on the web forum where I posted it, just not in email I guess)

Thank you, your advice helped a lot.  You were right, the processes were all hanging around and when i killed them and got a fresh start, things started up much better.

I now have engage_media_proxy in a place which should be hit only when there is no totag (please confirm this?):

        if (has_totag()) {
                # sequential request withing a dialog should
                # take the path determined by record-routing
                if (loose_route()) {
                        if (is_method("BYE")) {
                                setflag(1); # do accounting ...
                                setflag(3); # ... even if the transaction fails
                        }
                        route(1);
                } else {
                        /* uncomment the following lines if you want to enable presence */
                        ##if (is_method("SUBSCRIBE") && $rd == "your.server.ip.address") {
                        ##      # in-dialog subscribe requests
                        ##      route(2);
                        ##      exit;
                        ##}
                        engage_media_proxy();
                        if ( is_method("ACK") ) {
                                if ( t_check_trans() ) {
                                        # non loose-route, but stateful ACK; must be an ACK after a 487 or e.g. 404 from upstream server
                                        t_relay();
                                        exit;
                                } else {
                                        # ACK without matching transaction ... ignore and discard.\n");
                                        exit;
                                }
                        }
                        sl_send_reply("404","Not here");
                }
                exit;
        }


>report back if you still see the problem with the syslog entries.

When I place a call from one NATTED device to another NATTED Device, I think it's trying to use mediaproxy but something is timing out... (and my SIP SDP does not tell the caller anything about the proxy address).  why might this be?  see following trace out:

By the way, my opensips and mediaproxy are on the same box, with only one (private IP) NIC, sitting behind a firewall 1:1 NAT, so in the mediaproxy config.ini i have dispatchers and listen, listen_management listed with the private IP (since i believe opensips itself needs to connect to this IP), and relay_ip as the public (since i believe clients will connect to this)
