I was under the impression that AT&T got their numbers indirectly too -- I'll look for that thread. (It explained as I recall why they did not have local service at all ATT Land-Line Rate Centers.)
EDIT: Can't seem to remember who holds many of the ATT CV numbers? (Help anyone?)
EDIT2: Had to go part way through sign-up to see what was available. NOTHING LOCAL for me!!!!
I selected a 248-242 number »
www.telcodata.us/telcoda ··· ange=242And the middle-man company I was remembering is TELEPORT COMMUNICATIONS GROUP AMERICA.
The point is: I don't think ATT CV is considered a CLEC (or what-ever the right terminology is) and is likely no more accountable than Vonage would be.
