How to silence your iPhone immediately when there is an incoming call

Phone ringing is embarrassing especially when you’re in a class or in a meeting. Even when you switch iPhone to silent mode, the phone will still vibrate when there is an incoming call. To quite the phone completely, you can just press once the Sleep/Wake button or either of the volume button. Your caller will see your phone as still ringing, but your iPhone will now be silent and stop vibrating.
