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.

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.

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

[–] [email protected] 2 points 7 months ago

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.

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.

[–] [email protected] 7 points 7 months ago

If you don't need external calls sip trunk is not needed.

[–] [email protected] 4 points 7 months ago

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.
