Call from what "appears" to be the same number as stated here, to my office, from Arizona?, I did not answer, they did not leave a message.

I received a call from the listed number. They left no msg. I returned call. Company is American Pacesetters 1280 South Country Club Drive
Mesa, AZ 85210-5145,(480) 784-2270. They do marketing research for trade publications

Telemarketers in action.  They have all cell phone numbers after these were released.  
They would not leave a message, which tells me the call is not important.  I would not waste my minutes calling them back.
