Cancelling Calls - option?

[jcww_99]

Hi,

With the iPhone when people call me, sometimes i get 2 option buttons
1) answer call
2) decline call

Sometimes i don't get those and instead have the slider option to answer but not to decline.

What circumstances do i get which option? Is there anyway to set the iPhone so the 2 option buttons come up all the time rather than the slide option?

ThanksQ!

Pressing the volume bar will silence the ringer. Although that may be more like ignoring the call.

I believe you can just hit the home button on top and it'll silence the call
