can you leverage google voice instead of twilio, using asterisk or some other pbx if necessary?

Probably, but the Twilio call is only two lines of code :)

I may look into other backends, but Twilio was by far the easiest to get going. Currently checking out Tropo and Teleku.

I ask because it looks like Twilio is a pay service (and i though GV was free)
