the number calls my private cell phone at least 3 times a week. saw the post about calling back and pressing #1 on the keypad. did it this morning, hope it works. when you call back an automated voice says "thank you for calling back, if you would like to be put on our no call list and not hear our special offers please press 1" or something along those lines.
Got the same BUT since they called on my company phone, I did answer and I played along (somewhat) until they asked for my address. A survey -- mostly likely Healthcare related (since that was a question). I did hear on Rush today that a group from the DC (202) area is calling Massachusetts residents slandering Scott Brown. Most likily the connection with this call -- hence why I tried to looked up this number.
