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?

If you happen to have a Fritzbox with VoIP capability it contains a SIP server and you can register SIP clients on it (e.g. Fritz App Fon, linphone, twinkle) and use them to phone internally.
