Hello I'm trying to figure out a way to automatically receive a call when i call from my cellphone for the gsm shield to pick up automatically from what i read in the 900 datasheet the command ATA should receive a call below is my sketch to send a call from my arduino to my cellphone I'm trying to go the other way around and have my gsm shield to receive the call automatically can someone please help me?

#include <SoftwareSerial.h>
SoftwareSerial SIM900(7, 8); // configure software serial port

void setup()
{
  SIM900.begin(19200);               
  SIM900power();  
  delay(20000);  // give time to log on to network. 
}

void SIM900power()
// software equivalent of pressing the GSM shield "power" button
{
  digitalWrite(9, HIGH);
  delay(1000);
  digitalWrite(9, LOW);
  delay(5000);
}

void callSomeone()
{
  SIM900.println("ATD + +1xxxxxxxxx;"); // dial US (212) 8675309
  delay(100);
  SIM900.println();

}

void loop()
{
  callSomeone(); // call someone
  SIM900power();   // power off GSM shield
  do {} while (1); // do nothing
}

The code you have, is for the arduino shield to call you. You want to call the other way ?

If you look about halfway down this long webpage, there is an example of how they receive an incoming sms to the arduino shield. I don't know about how to get an actual call. I don't know what you could do with an actual call if you got one.
