My house phone is through Comcast - and I blocked the allowed number of callers on Comcast, filled my Panasonic phone block (250 numbers) and have since signed with nomorerobo through Comcast (free with Comcast). It blocks all unidentified numbers and seems to be working quite well.
And I have an unlisted number - cannot imagine what it would be like with a published number.
