3 Make Voice Call
4
5 This sketch, for the Arduino GSM shield, puts a voice call to
6
7 a remote phone number that you enter through the serial monitor.
8
9 To make it work, open the serial monitor, and when you see the
10
11 READY message, type a phone number. Make sure the serial monitor
12
13 is set to send a just newline when you press return.
14
15 Circuit:
16
17 * GSM shield
18
19 * Voice circuit.
20
21 With no voice circuit the call will send nor receive any sound
