One new feature in iOS 8 is the ability to answer incoming phone calls on your iPad if it’s in range of your iPhone and both devices are on the same Wi-Fi network. When OS X Yosemite ships, most likely later this month, you’ll be able to answer calls on your Mac, too. It’s great if you keep your phone in a bag or purse, or if you want to see who’s calling before reaching for the phone.
In the last day, though, I’ve had two frustrated people ask me how to make the iPad stop ringing when a call comes in. It is a feature you can turn off, but the setting isn’t obvious. Here’s how to do it:
- On the iPad (or other iOS device) running iOS 8, go to the Settings app.
- Scroll down to the FaceTime settings and turn of iPhone Cellular Calls.
Now, when a call comes in, you can ignore one device instead of two or more.

The voices inside my head tell me that there is a similar preference for FaceTime in OS X 10.10. (☜Those voices didn’t sign an NDA.)
