Prevent Calls from Specified Phone Numbers and Email Addresses
When you don’t want to receive FaceTime calls from certain people, follow these steps:
Open the iPad’s or iPhone’s Settings app. (Use Spotlight Search to find it quickly. ) In Settings, scroll down the left-side menu and select FaceTime. This will bring up the FaceTime settings on the right-hand side. (On iPhones, scroll down and tap FaceTime to bring up FaceTime settings. ) Look for the section You Can Be Reached By FaceTime At and tap to remove the checkmark next to any phone number or email address for which you don’t want to receive FaceTime calls. Tap to add a checkmark for any you want to be active. You can also add a new email address to the list. FaceTime calls will now ring only for the accounts you’ve selected.
