Receive Voice Call
This sketch, for the Arduino GSM shield, receives voice calls,
displays the calling number, waits a few seconds then hangs up.
Circuit:
* GSM shield
* Voice circuit. Refer to to the GSM shield getting started guide
at http://www.arduino.cc/en/Guide/ArduinoGSMShield#toc11
* SIM card that can accept voice calls
With no voice circuit the call will connect, but will not send or receive sound
