[OpenSIPS-Users] How to get all listening socket IP address as variable

[Muhamad Putra Abdullah]

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.

Hi,

socket=udp:enp1s0:5060 tag INTERNAL_IP  # CUSTOMIZE ME
socket=udp:enp2s0:5060 tag EXTERNAL_IP  # CUSTOMIZE ME

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)

Hi,

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.

Hi,

I have 2 listening interface for opensips 3.2. How do I get both IP address to be used as variable in opensips config file? I try to use socket_in/ socket_out but failed to get the other interface IP address.

Thanks
