Self-hosted IP-phone network
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?

You will want a couple things. First get yourself some VoIP phones. Yealink is a decent brand. Grand stream Wave is a good option for Android and iOS softphones.
Secondly download a PBX. I recommend Fusion PBX others will recommend 3cx but the main thing is to avoid Asterisk.
Finally get yourself a SIP trunk from a phone provider.
Now cry in pain as you are constantly bombarded with SIP attacks in your home.
Interesting - why avoid asterisk?
I looked into fusion to play with but I’ve been using asterisk casually since like the 00s with no issues.
Owned by a for profit *aaS provider whose motivations are money.
Fusion PBX is a front end of freeswitch is not. Mark and the team at Fusion are top notch with their support.
Is fusionpbx completely open source? Do you have any further reasons why you would recommend it?
I was looking into asterisk the last couple of days for a new company PBX and need some alternatives to compare against. Asterisk looks also a bit complicated though not impossible
mostly open. Here is the git repo for FusionPBX so you can see. https://github.com/fusionpbx/fusionpbx
Super easy to get off the ground. Here is the install page https://www.fusionpbx.com/download.php
We used it as a multi tenant hosted pbx back when I was working for an ISP. works really well.
Ah yes that makes sense. I was taken aback by my latest install of freepbx. I feel it wasn’t as aggressive during the Digium days but it definitely left a bad taste in my mouth.
I heard good things about free switch, although it seems like a paradigm change. I’ll have to check it out.
What's the problem with Asterisk? FreePBX uses it and as far as I can tell, it's the only way to get Lenny working.
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.
