Haven't had problems for months, but this number called at 9:55 AM, then 4:27 PM. A short time later at 4:43, I was called by (410) 774-8191, a telemarketing number. Another telemarketer, (313) 263-2663, has also called me in the past week. Have not answered or called back and none of them left messages. Can only assume it's a scam doing a wide sweep to look for valid numbers around the holidays.
