FastDisa is being created to duplicate the features of Google Voice for mobile users with the help of Asterisk.
Call Routing
It contacts the Asterisk server over the internet and configures the call routing. When your phone dials, it dials your Asterisk server which follows the route.
If internet is not available, the app will still dial though using DTMF tones to route the call.
SMS Support
Maybe we'll get this integrated in the future. For now I'm using Twilio Hosted SMS and the app from textable.co which is working just fine.
See The Project Brief for more info.
