We get several calls a day from this number. We won't answer because we do not know who it is.

I recieved several calls but no message from this number. I checked my caller ID and called the number back. There was an automated message for Stone Bridge Life Insurance. The recording refered you to an 800 number if you where interested.

American Laser Skin Care

I also have received several calls from this number. What did you do to cancel the calls?

I called this number back on my cellphone after receiving the original call on my home phone with 'unknown name' in the caller window

The answering party identified with a recording " all representatives are busy....leave a message..."
and here's the "money shot"

the caller was: DIRECTV.... very suspicious that call was generated from an apparently local number...

UPDATE: after reading the remarks above that the same number sourced other different telemarketers I suspect it is one of those "dial a deal" numbers; every time this robodialer rings at your home the  minute you answer and the line goes "hot" a possibly different telemarketer is matched to the pickup...
