Hello I'd sure like more information on configuring the gcloud version of 3cx debian. 3cx install script is excellent... My local phone is behind a firewall. I opened my gcloud IP address to my local phone as well as usual 3cx ports. Entered the gcloud IP address as proxy, with user ID, pass, as per usual setup. Phone fails to register with error 408. phone is spa504g on 3cx graphical window under extensions I have the options to use outside of lan set. Is there a way to use SBC tunnell for connections to gcloud version of 3cx debian? I am challenged to configure a tunnel? As I don't find option on the graphical display... What am I missing?
