How To Silence Unknown Callers on iPhone

To screen or silence unknown calls on Phone or FaceTime, use the following steps:

1. Go to Settings as shown in the image below.

3. Now choose Phone or FaceTime.

If you have chosen the Phone app, then:

Find the option: Screen Unknown Callers. Tap on that.
Now you will see 3 options: Never, Ask Reason for Calling, and Silence.
If you choose Never, the phone will ring for unknown numbers, the way it rings when a saved contact calls you. If you choose Ask Reason for Calling, the phone will first ask the caller the reason for making the call before it rings. If you choose the Silence option, then the phone will go silent when an unknown number calls you.

If you have chosen FaceTime, then:

There will be an option to Silence Unknown Callers as shown below. You can turn it on to silence calls from unknown numbers. The system will move these calls to voicemail.

Make sure you save important contacts- like your child’s school bus’s contact number, your doctor’s contact, your family members’ numbers, etc. before silencing calls from all unknown (unsaved) numbers.
