When call off-hook, saves current DND state and sets it to totally silent to prevent notifications' vibration. When call ends it returns it to saved state.
You can also switch to more stable mode, that uses ringer state settings, but on some phones it is not working as it should.
Very low power consumption (thanx to "When changed" events)
