Someone in Killduff is in on the scam, but perhaps with a level of
plausible deniability inherent to revenue-sharing agreements.

But the precise figments of routing that make this possible within the
ICC/CABS environment after the 2011 FCC "USF/ICC Transformation Order"
might be quite baroque. It's hard to say without the LERG handy. They
might be using a CEA. I don't know.

See FCC 19-94 for background info on these concepts:
