This number calls every day. A recording says 'Please press one', then hangs up.  Has been calling for at least 7 weeks, only on weekdays

Same Here, sometimes with an Area Code, but lately without.  Been going on for about 19 weeks.  Every weekday between 0900 and 1300 there will be a call from this number in some form.  At first I though it was for my Daughters student loans, as she moved and mail wasn't forwarded correctly.  But that has been cleared up sense October, ans the call continue to this day.  Thing that make you go Hmmmm!  I put SIT tones on my answering machine and it cut down most of the calls, but this one persists.
