Michigan has mandatory thousands block pooling, and active LNP in most
of those exchanges. I'm sure many of these other states are the same.
Blocking this is a really dangerous thing to do, even if you don't care
that the FCC would take a dim view. 906-204 for example has cingular
cell phones in it.
