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

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.
