Sitting on my desk is a chipset test unit (called a Surf). Since the chips that we make are primarily used for cellphones, this unit functions as a cell phone and is registered and on the air with AT&T wireless most of the time, and has a valid phone number. It also is programmed to automatically answer and plays all audio through the regular telephone handset connected to it.
Just now, I heard a woman's voice, and realized that it was coming from the handset for the test unit. I picked it up and listened to part of a recording advising me that it wasn't too late to get extended warranty coverage for something -- either my car or possibly my cell phone.
So, not only did they make a recorded cold call to a cell phone, but to a cell phone registered to a company and used on test units. They did not make a sale.
