How to block or screen calls that don't show up on the caller ID

How to block or screen calls that don't show up on the caller ID

I am having trouble screening out calls on my voice service from a caller that shows up as an unknown number number unavailable.  Is there a call blocking feature that I am missing?

Make sure you have "block anonymous calls" checked in Xfinity Connect / preferences / voice / call blocking.

That will block a few calls but for you to block all the unknown or out of area calls, check out this link:http://forums.comcast.com/t5/Voice-Service-and-Equipment/unknown-number-out-of-area/td-p/1713421
