So I was using a lifeproof case and had some weird beep noises right before I connected a call. The noise goes away if noise cancellation is turned off. So I decide to do some investigating.
I just discovered that when the phone is removed from the case, if I cover the earpiece with my finger and make a call, I can hear the same beep from the earpiece! WTF? What is going on?
