What I do is use ncid. In addition to the FCC bad list, I have two additional block scripts. One instantly blocks V telemarketers. The other silently hangs up on any new caller. Serious callers will think there was a glitch and call again, this time getting through. Meanwhile, I get a lead time to research the number with say 800notes to see if it should be permanently blacklisted.
