Called office just now. First it rang twice but no Caller ID came up, which usually means the caller hung up. However, during the 2nd ring, it stopped and then started again and this time this number came up. I answered with co name to hear a robot saying (but it sounded like it was cut off at the beginning) "...message for..." and I hung up at that point. We're nowhere NEAR AZ and I've added this number to my "pick up, hang up" numbers.
928 area code is for an area in Arizona, reverse search says its likely coming from Flagstaff metro area and that its a cell phone, but thats all I could find.
I know that doesnt help anyone much, but maybe it will give someone else a foot up on looking.
411.com will do a further search and will let you know if there are names connected to the number or not, for $2 you can have them charge your phone plan and text you the name - be sure to text stop directly afterwards though or you will keep getting messages that they may or may not charge you for.
