[SR-Users] rtpengine does not send RTP packets out

[Juan Perez]

thank you Richard, yes the IP is local to the machine:

./rtpengine --interface=pub/<PUBLIC_IP> --interface=priv/10.0.2.68 --listen-ng=127.0.0.1:7722--timeout=30 --port-min=35000 --port-max=65000 --log-level=7 --log-facility=daemon

The PUBLIC_IP is a NAT that the machine has, it is a virtual machine (Amazon), so it is not configured on any interface in that machine.

But the Private one it is configured on the eth0:

[root at ip-10-0-2-68]# ifconfig
eth0      Link encap:Ethernet  HWaddr 12:23:49:EF:3A:53
          inet addr:10.0.2.68  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::1023:49ff:feef:3a53/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:9001  Metric:1
          RX packets:161973 errors:0 dropped:0 overruns:0 frame:0
          TX packets:102009 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:117022408 (111.6 MiB)  TX bytes:20614133 (19.6 MiB)
          Interrupt:247

This is how kamailio is setup to communicate with rtpengine and it is the only line I have manually configured for that module in the kamailio config file, everything else is by default

:

# ----- rtpengine params -----
modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:7722")

This is the line I have on the Route section to forward the INVITE to the Asterisk:

 rtpengine_offer("direction=pub direction=pub replace-origin replace-session-connection");

The whole Route section is this:

route[TO_FS] {
        # here we load the Asterisk GWs that will be used to send the calls out.
        t_on_reply("TO_FS");
        t_on_failure("TO_FS");
        $var(result) = load_gws(10);      
        rtpengine_offer("direction=pub direction=pub replace-origin replace-session-connection");

        xlog("L_INFO","mylog: TO_FS: Call received. Loading LCR_GRP 10\n");
        if (!load_gws(10)) {
                xlog("L_INFO","mylog: TO_FS: After, GW_URI_AVP: $avp(i:709).\n");
                sl_send_reply("503", "Unable to load destination gateways");
                xlog("L_INFO","mylog: TO_FS: Destination GWs load section failed!. Load_GW function.\n");
                exit;
        }

        if(!next_gw()){
                xlog("L_INFO","mylog: TO_FS: After, GW_URI_AVP: $avp(i:709).\n");
                xlog("L_INFO","mylog: TO_FS: Destination GWs load section failed!. Next_GW function.\n");
                sl_send_reply("503", "Unable to find a gateway");
                exit;
        }
        xlog("L_INFO","mylog: TO_FS: Destination GWs load section OK.\n");

        if (!t_relay()) {
                xlog("L_INFO","mylog: TO_FS. T_Relay failed. Method [$rm].\n");
                sl_reply_error();
        }

        exit;
}

And this is the line I setup when I manage the Reply from the Asterisk:

onreply_route[TO_FS] {
        xlog("L_INFO","mylog: OnReply Route TO_FS.\n");
        if (has_body("application/sdp")) {
                xlog("L_INFO","mylog: Starting rtpengine session. Answer\n");
                rtpengine_answer("direction=pub direction=pub replace-origin replace-session-connection");
        }
        exit;
}

Seeing as you're using the "direction" options, can you double check
that the local IP addresses that you've configured at the command line
are actually addresses bound to local interfaces on the machine?

cheers
