Hi Putra,

Actually a recent fix should allow in the latest 3.2 version to use the socket's tag when setting the outbound socket, like :

socket=udp:enp1s0:5060 TAG internal   # INTERNAL_INTERFACE (192.168.1.2)
socket=udp:enp2s0:5060 TAG external   # EXTERNAL_INTERFACE (DHCP)
...
....
$socket_out = "external";

But use the latest 3.2, git or nightly builds.

Hi,

I see, you start listening on an interface (enp2s0), which translates into the DHCP IP, but you can not use the socket/listener to do a force send socket ....as there is no way to reference it. Unfortunately something like that is not possible right now, but I see it as a valuable addition.

For the moment, what you can do is to use some pre-processing  (see [1]) in order to fill in your CFG the actual IP - and do an IP detection from the opensips init.d / startup script.

    Hi,

    Ok. I’m totally in learning process.

    Let me explain my test deployment. I have 2 separate network that
    connected via opensips server.

    Internal SIP Server                                       Opensips
    Server (2 NIC)                         External SIP Server

    (User 634) 192.168.1.1  - - - - - - - -  192.168.1.2    |
    (EXTERNAL_IP) DHCP IP - - - - - - - - 172.16.16.1 (User 605)

    What my intension is to relay calls between Internal and External
    SIP server via Opensips server.

    I use this method to achieve this:

    socket=udp:enp1s0:5060   # INTERNAL_INTERFACE (192.168.1.2)

    socket=udp:enp2s0:5060 # EXTERNAL_INTERFACE (DHCP)

    .

    .

    # From Internal to External

    # Testing one number only first 634 to 605

    if ($rU=~"^605") {

                   sethostport("EXTERNAL_IP:5060");

    $socket_out = "udp:EXTERNAL_IP:5060";

    rtpproxy_engage("ier");

    route(relay);

    exit;

    }

    # From External to internal

    # Testing one number only first 605 to 634

    if ($rU=~"^634"){

                   sethostport("192.168.1.2:5060");

    $socket_out = "udp:192.168.1.2:5060";

    rtpproxy_engage("eir");

    route(relay);

    exit;

    }

    I have no problem on call from external to internal because I know
    the IP address of internal opensips server, the problem is call
    from internal to external.

    Is there better solutions than this?

    If so, when you receive a request on the external IP, the
    $socket_in(ip) should return the actual DHCP IP.

        My INTERNAL_IP is set to static and EXTERNAL_IP set to DHCP. I
        just use tag to test something.

        Hi,

        How do you define the listening socket in OpenSIPs cfg ? (the
        one related to the DHCP interface)

        Regards,

            Is there a way to get the IP address of DHCP interface to
            use in the script? I can get the call go through if I set
            both the interface as static.

            Hi,

            via the socket_xx() vars you can get only the sockets
            relative to/used by that call, you cannot iterate thru the
            listening sockets.

            Regards,
