      <br>
      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.<br>
      <br>
      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.<br>
