How to Block Phone Numbers on Comcast Digital Voice

Comcast offers several features that allow you to choose which calls you answer. You can block up to 12 telephone numbers with the call screening feature. Anonymous call rejection restricts calls from numbers masked as "anonymous" and "private." You can also block caller ID before placing an outgoing call. With the exception of the 900, 976, 700 and 500-number call blocks, you can enable and disable each feature using your personal telephone.
