Sounds like you need AI call screening.

Don't know when that will get here, but when it does (and better AI-powered spam filtering), I think a lot of these problems will disappear, and a lot of sales teams are going to have to rethink.

Google Fi has screening you can enable either for all unknown callers automatically or manually by tapping a button when the call pops up.
