In the Phone section of the Settings app in iOS 13, there's an interesting new toggle called "Silence Unknown Callers," which appears to do exactly what the name suggests. With this feature enabled, calls received by people not in your contacts list seem to be sent straight to voicemail.

We tested out the Silence Unknown Callers feature this week, and it worked well. When an iPhone with the option enabled received a call from a number that wasn't a known number in contacts, the phone never rang - the call was sent directly to voicemail.

While we haven't done extensive testing, we did try introducing an unknown number by referencing it in an email because iOS can recognize phone numbers that way, but even when the number had been previously sent to us, phone calls from that number were still muted.

Silence Unknown Callers seems to be an effective way to limit incoming calls to numbers that you already know, blocking out the rest from causing your phone to ring.

It's a simple, useful solution to the deluge of spam calls that many of us in the United States receive on a daily basis. It's not identifying spam calls or risky numbers specifically so it's not the most elegant solution available, but it works for cutting down on unwanted calls.

This isn't a setting that you're going to want to enable if you're worried about missing some legitimate calls from numbers that you don't know, but all calls do go to voicemail, so when a legitimate call does come in, you can just call the person back.

Silence Unknown Callers will be available to everyone this fall when iOS 13 launches alongside new iPhones.

Love this! And I hope they mean exactly what you say (if # is not in contacts list)... not just the caller ID displaying "unknown caller". Since telemarketers mostly use fake phone numbers, caller ID won't appear as "unknown".

Hopefully that makes sense, I've been waiting for the option to only allow contact list calls forever!
 
I implemented this feature a long time ago by making a silent ringtone my default ringtone, then giving each person in my contacts I actually want to hear from their own audible ringtone. In the infrequent case I'm waiting to hear from a number I don't know that would otherwise be silenced, I temporarily switch from a silent ringtone to a real ringtone.

The new feature would be a lot simpler though, and would not require me to maintain my silent ringtone file.
 
How does this work? Like if a friend of mine called me from a number not on my contact list. Would it still ring to me? Or is it literally only for when it says unknown number on the caller id?

I can assure you, that’s how it works!!
Loving it. =)

Brilliant! I used to do that with my old semi-intelligent phone in Japan (pre-iPhone days). They were flip phones and their LED would light up when a call came in. I'd set a different color flash for each person who called or default. Ah, those were the days.
