A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

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.

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.
