Sketch for making a Voice call with single push of a button - Not working...

Hi to all
i have this sketch

// libraries
#include <GSM.h>

#define PINNUMBER ""

// initialize the library instance
GSM gsmAccess; // include a 'true' parameter for debug enabled
GSM_SMS sms;

// constants won't change. They're used here to
// set pin numbers:
const int buttonPin = 6;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup()
{
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);     
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);     
  // initialize serial communications
  Serial.begin(9600);
 
  Serial.println("SMS Messages Sender");

  // connection state
  boolean notConnected = true;

  // Start GSM shield
  // If your SIM has PIN, pass it as a parameter of begin() in quotes
  while(notConnected)
  {
    if(gsmAccess.begin(PINNUMBER)==GSM_READY)
      notConnected = false;
    else
    {
      Serial.println("Not connected");
      delay(1000);
    }
  }
 
  Serial.println("GSM initialized");
}

void loop()
{

if (buttonState == HIGH) {   
    // turn LED on:   
    digitalWrite(ledPin, HIGH);

  if(vcs.voiceCall("+12345678"))
        {
          Serial.println("Call Established. Enter line to end");
          // Wait for some input from the line
          while(Serial.read()!='\n' && (vcs.getvoiceCallStatus()==TALKING));
          // And hang up
          vcs.hangCall();
        }
        Serial.println("Call Finished");
  }
  }
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

But i get error while trying to upload it.
Please can anyone post a working sketch for making a voice call with press of a button (not with asking to enter a phone number etc…) only press of a button and then call

Thanks

This is compiling and uploading with no problem…can someone let me know if it will work

          // And hang up
          vcs.hangCall();
        }
        Serial.println("Call Finished");
  }
  }

Question 1 : will it work if i connect directly pin 2 to 5V with a button so by pressing it will make connection between pin2 and 5V or it is nessecary to connect pin2 to GND with 10K resistor and with switch to 5V

Question 2: as i understand arduino gsm shield and arduino uno are connected to upload our sketch. After we have uploaded our sketch, will the gsm shield work without the arduino uno i we power it up with the 5V (given normally from the arduino uno to the gsm shield) or they need to be connected together all the time to work.

Thanks

Hi:

Remember you have to add the voice circuit for the sketch to run, if you want to be able to hold a conversation.It is described here: http://arduino.cc/en/Main/ArduinoGSMShield Regarding the questions: 1-Use the resistor, otherwise when the switch is open the input would be a random value. 2.-The Shield has to be connected to the Arduino UNO. The Arduino runs the sketch and sends commands to the shield (such as "call", "hang", etc...)
