I want to address this. Samsung has this feature; I turned it on on my phone since day 1. I didn't use to get scam calls like this; I don't know if it's the beta 3 on my fold, but I've been getting scam calls like crazy, probably about 4 - 5 calls a Day. That's annoying knowing that the feature on my phone supposed to block them automatically, and I believe it's not the beta as my S21 Ultra still getting scam calls, but I get more on my fold which I'm using the beta on
Responsibility to block known spam & scam calls also lies with the carrier and the user. I use nomorobo to block potential spam calls and route them to voicemail (in case it's a legitimate call, I can call back).
There are plenty of VOIP numbers available, however: scammers buy hundreds of numbers at a time, and their computers are calling thousands of people as fast as possible. It's unlikely we'll ever be able to block everything... so we do what we can.
