The only way to get to the bottom of this is probably just applying for a relevant job at AT&T, get accepted by whatever means necessary (low asking salary, nepotism, etc), check their network configuration yourself, then immediately submit your resignation once you're satisfied. I think I read somewhere about someone who did exactly like this in a software company. A new employee showed up, immediately fixed a long-standing bug, then submit their resignation.
