saw it said unknown name, picked up briefly, live individual on other end of call, hung up

Call says FL.  Unknown number so blocked it the future.  Scammers just changing numbers.

The Caller ID only shows this caller as OUT-OF-AREA only. This caller keep on calling at all hours of the day or evening repeatedly. This caller never ever leave any message upon my answering machine. And if I try calling back this caller never ever answer my call, and let the phone rings off the hook instead. I am only able to block so many of these type of callers at one time. I wish there was some way I could block this type of caller.  My Home Phone system only lets me block a limited numbers of callers.  Moreover,  my Home Phone landline provider only lets me just block a limited number of local numbers. There's a lot of misunderstanding with the "do not call" list. It only keeps legitimate marketers from contacting you, not the unscrupulous ones. That's why most of them hang up. They're hoping for a live voice, preferably a senior, who they can catch off-guard and spew their nonsense, and maybe even get a credit card payment. I have caller ID and I just don't pick up calls from numbers I don't recognize. And never, ever has one left me a voice-mail! Better federal legislation is desperately needed, but good luck with that. The most you'll ever get is a crappy Sunday news conference by a phony or worst, but nothing will ever happen.

Called it back its a auto warranty company trying to get you to extend a warranty on your vehicle.

When I called them back, they said they were a debt collection agency. definitely a scam if they're claiming to be different things.
