I have searched and can not find anything on using this internally. I don’t want to use a sip provider. Can I not just set this up as a internal server, have extensions to have internal communications?
I setup extensions, do I need to setup a trunk still? Everything I see shows me connecting to a provider.
You basically don’t set up any any outbound routes. With any switch I’ve built, I make sure I can call from extension to extension before even connecting it up to the outside world.
