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?
I’ve been running 3CX for a couple of years with a Voicehost trunk configured. I found it much simpler than free PBX to setup and maintenance has been a breeze. There’s apps or a web based option too. 3CX can be a little picky with older unsupported hardware - the old Cisco phone I bought was a tricky setup, but the Yealink I have phone was plug and play easy.
The tricky bit was configuring the opnsense router and firewall to correctly handle all the ports properly, but I think that’d be the same for any solution and for an internal only option probably not required.
