These are calls from a creepy organization in Phoenix, AZ called The Goldwater Institute.  They are trying to destroy public education in Arizona!

They call more than once a day and the recording says that they help fund educational costs for children.  We don't have any kids, so this is getting very annoying.  Went to the website that they mention in the recording and there is no contact info anywhere to be found except a company called "Goldwater Institute" which nobody answers on the number listed...If they piss me off enough, I'll go to the goldwater building and make a complaint in person.

I also received a rash of these calls in a day.  Fortunately I have Callcentric so they got a "number disconnected" message each time.  But they still called!

i highly suspect this is a spoofed number. Calls numerous times in a row. For personal reasons we keep our (land line) voice mail off and ringers turned off. Just too many telemarketing and faked calls such as this.
