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.

When I have a call routing issue, I look up what the LRN is of the
number I'm sending to. I then look up that NPA-NXX in telcodata.us to
find who the incumbent is in that rate center. I then look up what the
tandem information is for that incumbent switch. Then I know whether
it is the tandem I'm connected to in that LATA or the other tandem.
Telcodata.us doesn't always have that information.
What's the path of least resistance to getting that data?
