Asterisk
Asterisk is an open source VoIP PBX system you can run at home, or even at your business. BALU has a number of folks on the mailing list who have Asterisk implementations including large-scale commercial use, but I decided to throw up a few wiki pages here to document my experiences as a brand new Asterisk user setting up a home installation. Please feel free to add to these or make any corrections.

p.s. If someone still has a copy of the presentation and/or the video on Asterisk that was taken at the Adama Brothers Produce meeting it would be great to get that content up on the system, or at least a link to it if they already live elsewhere on the internet.
