Just for fun, a few associations I’m part of want to set up our own IP-phone network, with our own phone numbers and such.
- Is this possible?
- How would one go about doing this?
- Does it have to be it’s own separate network or can it work via the internet without special setup beyond a public IP?
If you don’t need external calling you don’t need a trunk, it’s just for connecting to the outside world. I found [[https://www.asterisk.org/|Asterisk]] was a good place to start. The config is rather involved though, so there are various front ends for it.
