Building a copper telephone network at EMF - Matthew Harrold

An overview of how I went from thinking about bringing a handful of analog telephones, to building a copper telephone network covering most of the EMF festival site.
I'll be going over the hardware and software I used, what I learned, what I'd do differently, and how people can help to make it better.
