I have now gotten a call from this number for about a week straight at about the same time.  Never leaves a message...thanks to this site, I know not to take the call.  Aggravating.

Calls my office phone, have see the same number on phones in conference rooms. Seems they just go down a cycle of numbers once they get a line phone.

Calling unlisted number... no business or reason for this call...
This is the first unwanted-caller that has called *twice in* just a few days.

I agree with HarryJ, cycling through the numbers...

called work phone; Ididn't answer; left no message.
