I find my true call is very effective since people have to say their name
and when I hear their name and have no idea who it is I hit the dump button.

The biggest problem with these things based on black listed numbers is that
when no number is there they have to get screened every single time and many
people in say nhs, or council simply hang up.

My concern with these systems is that I might lose a legitimate call.
The unknown name might be a courier delivering a package I have been
waiting for, it might be a nurse in the hospital phoning on behalf of
one of my relatives, someone's partner, someone who has found my
property in the street etc. I'm not saying I accept all the calls but
the cautious side of me likes to make the judgement myself.
