I got a call from an unrecognized Out-Of-State number. No message was left. As usual, I did not answer, and I looked up the number here. (800Notes is my go-to.) Thank you all for posting your experiences! I will be adding this number to my "Telemarketer" contact, which has a silent ringtone and is blocked. (I won't be bothered by this number again.) Out-Of-State Number + No Message = Scamarketer.
Called my cell. No message left. If I'd even noticed I received a call (I was driving and the radio drowns out my phone), I wouldn't have answered it anyway.
