cmoore@brl.mil describes the process for a NY Times/CBS News poll:

How pray tell can they have generated 'telephone numbers ... formed by
random digits, thus permitting access to both listed and unlisted
numbers' and then caused them to be 'screened so that only residences
would be called?' Is there some magic way to tell if a number is
residential or commercial, especially the unlisted ones. Or is this
simply a case of a newspaper article mixing facts and fiction?

[Moderator's Note: I think they made the assumption (mostly correct)
that business phones would probably not be non-pub; thus in the
process of sorting out who to call and who not to call, all non-pubs
were assumed to be residential for the purpose of filing the number in
one compartment or another.   PAT]
