The "caller ID" shown by caller ID phones uses a different mechanism
and a different information source than that accessible to emergency
services, toll-free providers and some others. They have access to the
unblockable (phreakers excepted) calling party number information used
for things like long distance billing. The biggest problem for the 911
system is inaccurate or incomplete data in the database that maps phone
numbers to addresses.

And VoIP providers who only track billing addresses, not the addresses
of the physical connections.
