iPhone X Unknown caller blocking?

[robertcoogan]

Does anyone know how to block calls from "unknown" or "unknown caller" on an iPhone? AT&T (my carrier) doesn't offer the ability (that I have found) to block these calls. The only other option is to allow calls via the Do Not Disturb settings - which isn't much help since it doesn't filter out based upon that criteria.

That’s what I had to do due to robocalls. You turn on “Do Not Disturb” and then the only calls which get through are those callers who are in your “Favorites” list. Here’s the catch: you have to specify the callers in both phone calls and text messages, otherwise a call will go through but a text message will be blocked (for example).
