hi there, I am trying to connect from different clients (iPhone, Windows 10 PC, etc.) with LinPhone to RasPBX, however clients cannot register. I tried two different versions of RasPBX, raspbx-03-12-2017 and raspbx-28-01-2017, no luck. Am I missing something on the RasPBX side or is pfSense doing something? Thanks, Savas
