//establish virtual serial port for shield

// the number of the pushbutton pin
const int buttonPin = 2;

// the state of the button:

//setup serial and pin states

delay(500);
}

void loop()
{

//checks to see if there is cause for panic
panic();

//looks to see if the GPRS shield is communicating
if (mySerial.available())
Serial.write(mySerial.read());
}

///DialVoiceCall
///this function is to dial a voice call
void panic(){

//get the current state of the panic button
buttonState = digitalRead(buttonPin);

//checks to see if the panic button is pressed
if (buttonState == HIGH){

//calls phone number
//replace with your own phone number
//if in the US, keep the 1 in the front
//otherwise replace the 1 with your country code

Serial.println("HELLO");

mySerial.print("ATD14155551212;\r");
delay(1000);
}
}

void ShowSerialData()
{
while(mySerial.available()!=0)
Serial.write(mySerial.read());
}

void powerUpOrDown()
{
pinMode(9, OUTPUT);
digitalWrite(9,LOW);
delay(1000);
digitalWrite(9,HIGH);
delay(2000);
digitalWrite(9,LOW);
delay(3000);
}

Have you read:

Edit your post and add code tags to the sketch.
Please use code tags. Use the </> icon in the posting menu. [code] Paste sketch here. [/code]

Yes you can just copy and paste.

You'll need to install the SoftwareSerial library (see the IDE's Sketch menu, Include library, Manage libraries).

The phone number goes in this line.

mySerial.print("ATD14155551212;\r");

do i just add the number or replace the ATD number with the phone number?

theuden:

AT is an 'AT command'. ATD means 'AT - Dial', the command to dial a number.

If your phone number is 502 123456789 I think the line needs to be

mySerial.print("ATD502123456789;\r");

The comment says you need to include the international dialling code, which is 502 for Guatemala. Sometimes to do international dialling you need to put a + first like this.

mySerial.print("ATD+502123456789;\r");

Also Some AT enabled devices need the \r\n at the end of the command rather than just \r

(I've found that's always sending \r\n works as the \n will just get ignored if not necessary. This is what println() does. It Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n').)
