Did not answer this number.

Didn't answer the phone.

Update: This is an AT&T telemarketer, trying to sell AT&T services.

This is a new annoyance. I had looked them up here before my answering machine's message finished playing. So much for the Do Not Call list! ALL unsolicited calls must be banned!

They say they are from AT & T , I have told them twice to take my name off their list and not call me back.

Called them back, left name and number to be removed from their calling list. They state they are AT&T and are calling about new products, etc. I left my name and number, we will see if it works.

Next day, they called back again. Leaving name & number on their "do not call" voice mail done no good. duh. Idiots.

this number calls all the time on my phone line

They call everyday for the past two months, never leaving a message and sometimes at odd hours. My phone number is unlisted which I pay for it to be. Who ever they are, it's annoying.

We got a call from the number and with the "Caller ID: Advanced Call C".
No messages but someone stayed long enough for the machine to engage...I don't like this...Hope they don't call again, ever! Enough of these unsolicited calls, alright...

Didn't answer..

constantly calls never leaves a message

Constant calls from this number.  Never leaves a message.

Time to switch service.

THEY CALL CONSTANTLY AT ANY TIME OF THE DAY
