That isn’t how the BT call blocking phones work.
You have an option of which calls are allowed to ring your phone, those in the phone’s phone book you have put in automatically do, but you choose to send international, phone box, number withheld, or anything not in the phone book to a ‘holding pen’. The ‘holding pen’ in the phone answers the call and tells the caller to speak their name and press a particular button on their keypad. Do that then your phone rings, don’t do that and the phone tells them to go away, and all without you being disturbed.
So for the automated calls, if you chose to look at your inbound call history you would see a whole bunch of (fake) caller id numbers that were rejected.
There used to be a problem with some calls from hospitals, banks, etc. where the staff calling didn’t know what to do, but these days they are more used to it, so just follow the required steps.
As for some sort of database of banned CLI numbers - hah! These people are crooks operating the other side of the world. What on earth could the UK do which would persuade them not to do what they are doing. And good luck to the UK trying to find a technological solution.
