They are a 3rd party for AT&T trying to get you to sign up for DSL. I have asked them numerous times to add me to their do not call list, and they never do. I get about 3-4 calls a day from them, and I never pick up.
Calls repeatedly and when I block them they call from a different number. Would love to put an end to these calls without canceling my phone service. All telemarketing should be illegal in my opinion. As long as they continue calling I will continue reporting the number.
I called the number from an internet phone and sure enough, it's AT&T. I think this is an autodial machine that is calling us to find out when we are home for their telemarketing calls. They drive me CRAZY!
UPDATE - I called the number during business hours. It is actually West Business Services, which works for AT&T. I asked them to put my number on their do-not-call list, which they did. We'll see if it works out!
