According to #3786 removed the reference to Leonardo only in while(!Serial) of the examples. Changed in in "wait for serial port to connect. Needed for native USB port only"

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
