Up to Android 2.3 you can not override the calling screen, but you can show a Toast message on it. The longest period of a toast is 3 seconds and after that it will dissapear. You can however create a thread that calls show() method of the toast every 2 seconds. Something like that:

Thread t = new Thread() {
        public void run() {

            try {
                while (true) {
                    if( isInCall ){

                        toast.cancel();
                        break;
                    }

                    toast.show();
                    sleep(1850);
                }
            } catch (Exception e) {

                Log.d("Exception: " + e.toString());
            }
        }
    };
    t.start();

You have to declare toast:

private Toast toast;

You have to init the toast object befor showing it.

toast = new Toast(getBaseContext());    
LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View layout = inflater.inflate(R.layout.toast, null, false);

    toast.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
