[VoiceOps] SHA Lookup

[Mary Lou Carey]

I'm assuming you don't have a subscription to the LERG because SHA 
information is in LERG 7 SHA. You can also find the incumbent for each 
rate center on localcallingguide and then go to the carrier's site and 
look up which end offices are associated with each tandem to figure it 
out that way. Or if you are interconnected with the LEC, just request 
the information from their trunk forecasting department.
