This one has been going for years. Someone claiming to be collecting money for some sort of police fund. Seems to be a recording because he doesn't know what I say back. When I call to check the number, I get a kind of busy signal but higher pitched than usual. Scam no doubt.
Didn't answer call. Knew it was not from someone I knew. I've stopped picking up calls from numbers that I don't know. If I do end up picking one up, I don't speak. If not a live person, I hang up. Sometimes, even if a person, I still hang up!
