These guys over in the what appears to be an "AT&T direct" forum appear to be able to help people. Might give them a shot, they seem to help many over there. The one I worked with was a "beach boy" but is now known as david is who fixed my problems with a rather weird problem with a dsl line.

Maybe he can help you guys and gals out too.
