I have 3CX Phone for Android installed on a Samsung Galaxy 4 Mini, and it works fine when I'm connected to my LAN via WiFi. But when I connect via a 3CX Tunnel then I see a first see a message "Registering", "Tunnel Connection" and finaly "Hung up" (massages traslated from Swedish). Then a message at the top of the screen says "Disconnected", then "Connecting...", then "Disconnected", "Connecting..." and so forth. I can make and receive calls, but it seems like something doesn't work as it should. I also have a Win7 machine with 3CX Phone which I also can connect via 3CX Tunnel and it connects without any problem. Any suggestion what the cause to this can be?
