received the same message yesterday on my home phone caller id.

Repeated calling. They don't leave a message. I don't recognize the number and won't answer or call back.

Scammers have been making phone calls claiming to represent the National Do Not Call Registry. The calls claim to provide an opportunity to sign up for the Registry. These calls are not coming from the Registry or the Federal Trade Commission, and you should not respond to these calls. To add your number to the Registry you can call 888-382-1222 from the phone you wish to register, or go click on “Register a Phone Number” in the left column of the DNC  home page. www.donotcall.gov
  Your registration will not expire. Telephone numbers placed on the National Do Not Call Registry will remain on it permanently due to the Do-Not-Call Improvement Act of 2007, which became law in February 2008. Read more about it at http://www.ftc.gov/opa/2008/04/dncfyi.shtm.

Comcast really should add more than 12 numbers we can block. Like 12 is great, but my cell phone can block unlimited numbers will the Call Control App.
