Install Asterisk/FreePBX on Raspberry PI with Google Voice.
I pay $30+ a month for a VoIP BYOD service, including selected World calling plan. I already have Asterisk in place at home but has to maintain a VM off Xen. With the powerful combination of Asterisk, Raspberry PI, and Google Voice, the cost is greatly reduced.
