Silence Unknown Callers

Hi skaurud,

"Silence Unknown Callers" is not designed to block all calls, there are exceptions as described here:

"This blocks phone numbers that you've never been in contact with and don’t have saved in your contacts list. If you’ve previously texted with someone using their phone number or if a person has shared their phone number with you in an email, a phone call from that number will go through."

There is further information here:

"Incoming calls will come through from people that are saved in your contacts list, recent calls list, and from Siri Suggestions to let you know who’s calling based on phone numbers included in your emails or text messages"

This information is from Detect and block spam phone calls - Apple Support.

If you still believe the feature is not working as expected, we would advise to contact Apple Support. They will be best equipped to investigate this further for you:
