I got 6 calls from this number to my office phone, while I was out teaching, or in the evenings when I am not there.
I called back and got a robot that told me this was moveon.org. That is a grassroots political organization.

I've got 7 or 8 of these all from times when I'm not in the office.  My company is looking into legal action.

This number has called my work cell phone (which is on the National Do Not Call Registry) at least six times today. I've called them back about 15 times, only to get the same unintelligible recording. It *sounds* like they're saying they are "MoveOn Dot Org," but I'm not sure. If anyone can find out who this is, please let me know - I'll be more than happy to drive down to Des Moines and pay them a visit and let them know exactly how I feel about being interrupted...
