New phone is better at actually catching voicemail messages than old phone, so I learned that the old-area-code spammers are the car warranty spammers.

The 800-number social-security scam stopped, counterintuitively, after I answered one and hung up on it a couple seconds in. 🤷

(That may have been coincidental; as annoying as it was I figure busting that one was probably a high priority for *someone*.)
