Looking for an AT&T contact that can update a prefix list

[joe at ngn-networks.com (Joe Freeman)]

If there's an AT&T contact on the list, or if anyone knows how to get a
prefix filter updated, I'd appreciate a response.

I put in a request for the update yesterday, and even called in to make sure
they'd do it, but it's apparently not done yet, and I've had a customer down
for hours waiting on it.

Thanks-
joe
