Silence ringer without hitting "ingnore?"

[The Weez]

With all of my previous [non-PPC] phones, when it rings/vibrates I could hit any exterior button to silence it but without hanging up. This would allow me to get out of a conference room and then pick up the phone when I was clear.

I can't find how to do that on a touch. I either answer it, or hang up.

Is this possible? Even if it's a particular button, it would be nice to have SOMETHING to silence only and not hang up.

Use the volume button on the left hand side. Up or down will silence without ignore.
