Here is an updated listing of the prefixes used with 800 toll free
service prepared for us by Bill Huttig <wah@zach.fit.edu>. This list
shows which carrier handles calls placed to 800-xxx numbers. Choice of
carrier routing on calls to 800-xxx numbers cannot be overridden with
10xxx routing. It should also be noted as in the past here that on
calls to 800 numbers, the called party either immediatly in some
instances or on a delayed basis receives a record of numbers which
called. This identif ication of the calling party cannot be overridden
with *67 or the 'line-blocking' associated with Caller-ID.
