How can I start a call via Intent, but make sure it goes via Bluetooth Headset?

Question

I can start a call with

  Intent intent = new Intent(Intent.ACTION_CALL);
  intent.setData(Uri.parse("tel://" + number));
  startActivity(intent);

But I want to make sure that when that call is started, it will be handled via the connected Bluetooth Headset, not via the phone's own mic and speaker. How can I do that? The solution can be specific to Samsung devices, if that helps.

Thanks a lot!
