intent.ACTION_CALL do not working with android kitkat -

I try to call the Android programmatically.

I handle the button event:

  btnCall.setOnClickListener (New View.OnClickListener () {@Override Click Public Zero (see V) {// TODO Auto-generated method stub intent intent = new Intent (Intent.ACTION_CALL, Uri.parse ("Telephone: 123456"); initialization (intent);}});  

But instead there is only the open dialer screen on the call screen.

Android KitKat 4.4.2GL-G
