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?

SIP providers usually sell numbers in contiguous series for businesses. For example, if your company buys a block of 50 numbers, the SIP provider then allocates XXX-5100 to XXX-5150.

But since you're keeping this strictly internal, you don't have to worry about that.
