These jokers can spoof your caller ID. They can make it display any number, functional or not. If they wanted to they could send 123-456-7890.
If you don't know the number. Let voicemail catch it. You can always call back if the call is/was legit..
Several "ring once" events, but did not pick up and did not call back. WhitePages says it's a VOIP number in Jasper, AL, but with VOIP, it could originate from anywhere. Seems like it's a phone-phishing scam. Don't bother calling them back.
