Just got a call from this number but no voicemail

Why not just answer it?  Why hide? Then we'd all know.

Answer next time.

What did they  say?

Why didn't YOU answer, Jimbo?  You must have received the call as well otherwise you wouldn't have looked up the number.  So why don't YOU  answer the call?

Best to NEVER answer unrecognized numbers or unknown callers.  Scammers have conned Americans out of millions and any caller hiding their identity or faking their number deserves to be ignored.

Call back gets, "please leave your number for 774-232-6412 (pause), service is not available."
This caller does not provide an identity on CID nor on voice response.
