Phone error ignoring a setting

Hi Supportme_,

It sounds like you may be having issues receiving calls from phone numbers that are not stored in your contacts. If that's the case, you'll want to check that Silence Unknown Callers isn't enabled on your iPhone. See: Detect and block spam phone calls

With iOS 13 and later, you can turn on Silence Unknown Callers to avoid getting calls from people you don’t know. 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.

To turn on Silence Unknown Callers, go to Settings > Phone, then scroll down, tap Silence Unknown Callers, and turn on the feature. Calls from unknown numbers are silenced and sent to your voicemail, and appear in your recent calls list.

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.

If an emergency call is placed, Silence Unknown Callers will be temporarily disabled for the next 24 hours to allow for your iPhone to be reached.

Before you turn on Silence Unknown Callers, make sure you have important contacts saved or you could miss a phone call that you don’t want to miss. The call will still go to voicemail and appear in your recent calls list, but you won’t get a notification while the call is ringing.

If your issue is related to something else, please provide us with more details.

Take care and thanks for posting here in Apple Support Communities.
