I think http://datec.web.att.com/faqs/telecom.htm is an internal AT&T webserver

Arrgh.. You're correct, and I should have noticed.
It's the 1996 FAQ for Telecom Digest,
Message-ID: <95.12.30.223ghbe6@massis.lcs.mit.edu>
TELECOM Digest - Frequently Asked Questions - v.7 17 December 1995
from newsgroup comp.dcom.telecom.tech

It's still in v.8 -

I've contemplated a project to make an independent VH database and I'm
looking for input as to whether anyone would care.

We currently maintain a searchable db of NPA/NXX info at
http://www.cctec.com -> Search -> Search for info on NPA/NXX

I wrote some code to take the Rate Center Name + State info and lookup the
lat/long and then translate it into V&H coordinates.

For one-off's and approximation of inter-CO distance, it will probably work.
The premise is "close is better than nothing". I'll also add a public
lat/long <-> V&H convertor to the mix.

For unknown CO's, we'd look for input from the community. Thoughts from the
group?

  I also have something similar here:

  Are you importing the nanpa data? that's where I am getting
my data from. There is a link off of my page to the
NANPA data which can be imported fairly easily.

I came across this one while writing dial-peers for a VoIP network that
went outside the North American Numbering Plan:

http://www.numberingplans.com

They sell a complete database for �249 (or �49/month subscription) but
also have a free tool to look up individual numbers.

I also have something even more similar, yet different:
