I did some phreaking as a kid (in the 1970's), but stopped when I turned 18. I learned a lot about phones in the process, and spent most of my career doing telecommunications engineering.
This article is from 2002 when it was probably still a lot cheaper to roll your own PBX than to buy one.
For the past seven years, I've been running FreePBX in a VM (in the same embedded, fanless server that hosts my OpenWRT router). I've got three full-featured VoIP desk phones with way more capability than the author's, and with a lot less effort.
