PhoneStateListener causing problems in outgoin calls

Question

Outgoing calls are ended automatically when phonestatelistener is used to monitor the calls. This is my code and when this is executed it blocks the outgoing calls :

public class CallHelper {
    public String number;
    private Context ctx;
    private TelephonyManager tm;

    private CallStateListener callStateListener;
    private OutgoingReceiver outgoingReceiver;
    SharedPreferences trackMeData;
    public CallHelper(Context ctx) {
        this.ctx = ctx;

        number ="";
        callStateListener = new CallStateListener();
        outgoingReceiver = new OutgoingReceiver();
        trackMeData = ctx.getSharedPreferences("LockedSIM", 0);

    }

    private class CallStateListener extends PhoneStateListener {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                number = incomingNumber;
                sendsmstoph(number);
                System.out.println("Incomgin");
                Toast.makeText(ctx, "Incoming: " + incomingNumber,Toast.LENGTH_LONG).show();
                break;
            }
        }
    }

    public class OutgoingReceiver extends BroadcastReceiver {
        public OutgoingReceiver() {
        }

        @Override
        public void onReceive(Context context, Intent intent) {
            number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Toast.makeText(ctx, "Outgoing: " + number, Toast.LENGTH_LONG).show();
            sendsmstoph(number);
        }

    }
