A few minutes ago I got a call frrom 865-249-0221, a number that has called me before with fake auto warranty coverage to sell. Right now I got a call from 865-415-0549, and I suspect it's the same people because the caller didn't leave any message when my message recorder picked up the line.

I would recommend not answering any calls from this number as well.  People who don't leave messages were not valid callers to begin with.
