I don't know about the USA, but in the UK it's done with something
similar to DNS. The telephone system looks up the first N digits of the
number to determine the operator it was first issued to. And places a
query to them. That either causes the call to be accepted and routed, or
they get an answer back saying "sorry, that number has been ported to
operator FOO-TEL, go ask them instead".
