muting the incoming call ring

A widely known but most useful tip.

If you are not in a position to answer an incoming call and just want to mute the call’s ring –  press sleep/wake button once or press the volume reduce button. Eventually it will go to voicemail if unanswered.

If you want to mute the incoming call’s ring and let it go to voicemail directly without ringing further press sleep/wake button twice.
