This is a SCAM to get personal information.  Sometimes claim to be a Charity (fraudulent).  She actually gave her name once Carolyn Kimbro.  And that is who the number is registered to.  1166 Kelton Avenue Columbus, OH 43206  (according to her Ohio Business Registration she runs some sort of catalog or list business.)  Reported to FCC and State of Ohio Atty General.
