[OpenSIPS-Users] Can I use loop back when there is no network link ?

[Bogdan-Andrei Iancu]

Hi Rodrigo,

Using lo or the 127.0.0.1 IP in the opensips cfg definitely works (I'm 
using the lo IP whenever I'm doing local tests with OpenSIPS, so it 
works for sure). Do you see the listener created (use netstat) ? also, 
do you see the traffic going to the right listener (use ngrep) ?

Best regards,
