I can't find an answer anywhere and just recently discovered this problem (I don't receive a lot of calls).

I put my phone on vibrate while at work but recently noticed that the vibrate turns off and the ringer comes back on.

For instance, I'll deny a call (swipe the red circle to the left) but the phone will make a noise for the voicemail. I sometimes leave my phone at my desk and don't want it to play all my inappropriate ringtones.
