2. Some phones default to playing ringtones from the external speaker to ensure you do not miss important calls.

3. If the ringtone playing from your phone is bothersome, try switching to Silent or Vibrate mode. Alternatively, adjust settings under "Ringtone Device" or "Bluetooth Headset Ringtone" (or any equivalent).
