The calls are being blocked... well, they'd have to be being blocked
*before they get to your gaining carrier, I guess, right?

That nearly *requires* the code to be in the LERG, so the originating CO
can execute it.  We have some people here who know the LERG back and fro;
Paul? Anyone else?  You ever heard of this?

Can you originate a call to that number from a different carrier via
PRI, and see which ISDN error you get back?  Or have someone else call
it that way?

ISDN errors tend to have a bit more data in them.

I'd do it, but I don't have any PRIs laying around anymore.
