[VoiceOps] Who do we call - 3rd plus party carrier issues affecting local customers

[Mary Lou Carey]

I would try calling AT&T's NOC and asking them if they can tell what 
trunk group they're receiving the call from. That might allow you to 
keep tracing the call back to the previous carrier until you find the 
culprit. I can send you their number privately.
