public class IncomingCallInterceptor extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {
    String callingSIM = "";
    Bundle bundle = intent.getExtras();
    callingSIM =String.valueOf(bundle.getInt("simId", -1));
    if(callingSIM == "0"){

    }
    else if(callingSIM =="1"){
        // Incoming call from SIM2
