[VoiceOps] AT&T Wireless call routing problem / contact

Hey, Does anyone know anyone / have any contact information for ATT Wireless engineering, or (even better) is there an ATT Wireless engineer who would mind contacting me off-list? We're seeing a problem with call routing to certain NXX, but only when forwarding calls to TNs in that NXX. Thanks, -- Nathan Anderson First Step Internet, LLC nathana at fsr.com
