RE: Access Numbers [OT]

It's a bit pricey, but the LERG by Telecordia is the best implementation of
rate center homing. It pretty much has everything you need to use in a
carrier-class enviroment. However, unless you have CLEC status you are tied
into the local ILEC's rate centers.

Show's look exchanges for the Bell Atlantic area... I'm sure other RBOC's
have these as well.
