Depends on what call management server you are using.
Asterisk-based has a module called Blacklist.
Finally, spam callers always spoof their numbers and blocking spoofed numbers without STIR/SHAKEN will be difficult if you have to "play by the rules". Shouting at the spammers, calling them with expletives, hanging up, etc. will not work. The fact that someone has picked up the phone means the number (or range of numbers) will be in their "hit list" they share among gangs.
If you want something that will work, you will need to implement Lenny. Once the spam callers find out your (range of) numbers have Lenny, and you are not afraid to use it, the scammers will remove your number(s) from their list.
