It was incredibly easy. Dump your phone carrier if you're already paying for phone service. Buy an old box off CraigsList (I got mine for $70). Get unlimited local and long-distance calling with Asterisk and GoogleVoice. You can even buy hardware to connect it to the existing phone wiring in your house and use regular old analong phones.
You don't even need to know that much about Linux. The configuration is all done thru a webserver that's built in to the OS too. You just point your browser at your box's local IP, input your username and password, and you're setting up your phone.
There's all sorts of cool features I've not even delved into yet, like dialing phone-to-phone in the house by assigning them extensions, attaching voicemail mp3's to an auto-generated email, etc. And it's all free, except the hardware.
