Call a phone number with your home phone without having to type it digit after digit. If your home phone is able to recognize a sound pulsation, it will listen to your smartphone for a "tone generated" phone number.
This application handles all international exit codes, whatever is your current country/network operator (even during roaming).
This application is really discreet, it binds to the call action of android, and provides a very simple launcher (with dual panel mode) to call each contact by DTMF sound code generation.
No ad, and free.
