How to Use Anonymous Call Rejection With Comcast Phone

Anonymous call rejection allows Comcast users to block calls from private or restricted phone numbers. Instead of the phone call ringing through, the caller will receive a message that the number does not take restricted calls. Activating anonymous call rejection can cut down on the number of prank calls and solicitors calling the user's phone. The service can be activated through the phone or online.
