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?
Is it possible to just run your own SIP-trunk? We’re not intending on sending or receiving calls from external numbers outside of our little network.
If you don’t need external calls sip trunk is not needed.
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.
