Turn your Raspberry Pi into a SIP hardphone with Twilio,Asterisk, FreePBX, and the Obihai OBi100

Those cheeky chappies over at Twillo (a web service that provides voice and text services) have posted a nifty little tutorial on setting up your Raspberry Pi with a phone handset & Asterisk (open source phone server) to receive calls over the internet!

Their example is a gentle into and uses their services but once you’ve got it up and running you could do all sorts of additional cool stuff with your new Pi Powered Switchboard!
