How Silence Unknown Callers feature works on iPhone?

Please explain how Silence Unknown Callers

feature works on iPhone. As far as I understand this feature was

introduced by APPLE with iOS 13 on about 7 May 2021.

Before that it was IMPOSSIBLE to block calls on iPhones (APPLE did NOT allow call blocking before).

I am trying to understand how exactly Silence

Unknown Callers feature works on iPhone? Do they apply a silent ring

tone in order to silence unknown callers? How do they do that?

Appreciate your detailed, step by step explanation (pls. keep in mind I’m not a programmer).

Thanks,

iPhone 13

If the caller is not in your contacts, or in your recent calls list as an answered call or a a call placed by you, the call will be rejected by the phone. If you have voicemail on your cellular plan, it will drop directly to voicemail where the caller can leave you a message.

I am not sure of the specifics of how it works, but for me, anyone who calls who is not in my contact list will go directly to voicemail. I never hear my phone ring. If they leave a voicemail, I will see the message.

I am not asking for that (I understand that). I am asking what is the process, step by step explanation.

So far it looks like that one option is:

1) to redirect the call to voice mail so that the caller can lеаve а меssаgе. This means the call is accepted (not blocked).

2) "the call will be rejected by the phone" what does it mean? rejected how? - so the phone will not ring? or will ring once and display a warning, or what will happen? or the phone will not send back to the caller any signal or confirmation at all (playing dead, not existing number) - please clarify.

Thanks,

So you have that feature activated and unwanted calls go directly to your voicemail.

Also there is no sound or vibration at all - correct?

This sounds good, meaning there is no disturbance at all (and that's the goal).

This brings a little clarity - thanks.

This text in the article - https://techwiser.com/what-is-silence-unknown-callers-iphone-how-to-use/

"Do note that the phone will still ring but you won’t hear the ringtone." makes me think that Apple does use a silent ring tone... how can I prove that?
