The real beauty of the Raspberry Pi is you don’t even need any extra hardware to do all sorts of cool things. We already have a full-featured Asterisk PBX running on the RPi complete with Google Voice for free calling throughout the U.S. and Canada as well as free worldwide calling through iNum access points. http://nerd.bz/QTtlIB You can take it for a spin by calling 1-843-284-6844. With a little luck, we’ll have the complete writeup on Nerd Vittles later next week.
Each Friday is PiDay here at Adafruit, be sure to check out our posts, tutorials and new Raspberry Pi related products. Have you tried the new “Adafruit Raspberry Pi Educational Linux Distro” ? It’s our tweaked distribution for teaching electronics using the Raspberry Pi.
