I have an iPhone 4S. I really don't know in which basis it shows Answer/Decline buttons when someone calling me. Sometimes it shows both buttons and sometimes it only show the option "Slide to answer".

enter image description here

The scenarios are,

  • The iPhone is locked/unlocked
  • The iPhone is in normal mode/silent mode

Note: I does not use Voice mail. I just need the "Decline" button in any mode/ any situation, because the mobile mode should not decide to hide the decline button. The owner of the mobile should decide it!

Push the power button on the top of the phone twice. The first time, the call is silenced. The 2nd time the call is rejected/directed to voice mail (if set up).

Thanks. Am I the only one who finds this totally non-obvious? :) Why aren't there buttons on the screen for this? – Andrew Ferrier Oct 8 '12 at 14:50
By the way, you can push any hardware button on the iPhone to silence a call, it doesn't have to be the power button. – bassplayer7 Oct 8 '12 at 16:26

When the phone is locked (the screen is off)

On iOS 6, it show slide to answer and a little phone, that, when you slide it up, shows more options, such as accept / decline and more options.

On iOS 5, it only shows slide to answer. Like Mark said, tap the power button once to silence the call, twice to reject it.

When the phone is in use (screen on, unlocked)

On All versions since the beginning of time, it will show Accept / Deny buttons.
