I get calls from this number all the time.  There is usually a delay in someone answering.  The most recent was yesterday morning at 8:13 a.m.!!   The man calling identifed himself as Frank from some air and duct cleaning service and asked how I was?  I replied not very good as it was 8:13, he'd woken me up and that it was FAR too early to be calling soliciting!  But of course he had already hung up. Grrrr!
