Called and immediately hung up when I answered. I am on the nation do not call registry, so I also went ahead and reported the number to them.

i got a call from this number @ 10:24 a.m. i didn't answer it because it's a scam they are trying to get your personal information don't give it out

Same. Called, I don't answer if I don't recognize the number or are expecting a call - figure they can leave a message.  Hung up before my voicemail could even answer.
Call from Slatington, PA.

Likely scammer, left no message. Blocked.
