Blocking a specific phone number on the comcast phone system?

Question

does anyone know how to block a specific number from being able to call you on the comcast landline phone system? and if you can ~ does the person you blocked know that they have been blocked from calling you?

Answer 1

My best advice is to visit Walmart and pick up a Zapper.

Every time a number calls you that you dont' want to answer, just push a button on the box and the box won't allow the call to come through from that number ever again.
