For this type of case it would be ideal if you could give him a passcode.

Couldn't be too difficult to set up a "unknown number" redirect that prompts for a pin, then forwards to a live line if correct.

This is adding more complexity. The solution is super simple, you should be able to report the number as spam, if a few other people report the number then the phone company will block the number and the phone company will have to pay the customers affected a small sum. You will immediately see the phone companies putting the work for detecting mass spammers, making sure that businesses that do mass calls have deposits for the case they abuse the system etc.
