Turning this feature on will only allow calls from numbers you've already interacted with, either via text message or because they've sent you their number in an email. Numbers that do not meet these criteria will be automatically blocked.
To turn on this feature, Go to Settings > Phone, look for the “Silence calls from unknown numbers” option and activate it. This will cause calls from unrecognized numbers to be automatically silenced, redirected to voicemail, and displayed in your call history.
The only calls you'll receive are from those in your contact list, call history, and those identified by Siri suggestions, based on numbers found in your emails or text messages. If you make an emergency call, the feature will automatically be disabled for 24 hours to ensure you can receive calls on your iPhone.
