I think I would agree. :)

So here is where the finer points of Asterisk pattern matching must
come into play.

All of the customer DID's match the pattern _NXXNXXXXXX. If we put
that pattern in the local context, then wouldn't that mean that calls
from a local customer to another local customer would match the
_NXXNXXXXXX pattern before even trying to match against the specific
patterns in the "clients" context? We need to be able to route
local-to-local calls without using two trunks to go back and forth
through the upstream provider.

Thank you for your input. I know this is a problem most operators can
get past, so there's got to be just something not lining up quite
right in my mental model. :)
