We need this as we want to attenuate music players even on silent
ringtone, to make the user aware the ringer is playing.

Use supplementary service notifications to display additional call info.

- If an incoming call was forwarded from another party, 'Forwarded call'
  is displayed as call type.
- If a call is held by the remote party, 'Waiting call' is displayed as
  call title.
- Some other events (e.g. forwarding state or conference call start) is
  displayed by (optional) toasts
