yes.. I used a filter. I should have read the Amazon reviews closer before bought the thing as some have mentioned that it doesn't work with DSL. The odd thing is the device seemed to work for about a month before acting up.
I'm now considering something one called a Digitone.
Amazon.com: Digitone Call Blocker: Electronics
But I hear there maybe be a newer version this year that allows more blocked numbers.
