- Actually, to my knowledge (the Mother of all Disclaimers), the PUC
- could *not* order this, nor make it stand. The FCC could, but state
- PUCs have no jurisdiction over interstate telecommunications, and the
- FCC tends to take a dim view of state PUCs attempting to claim
- jurisdiction over interstate matters. The FCC, as far as I know, is
- considering this issue even as we speak.

- I believe Bellcore TRs specify that this must be provisionable on a
- per-IXC basis in each CO, FYI.

- It's technically feasible, but outside their jurisdiction for
- interstate calls.

-
- Ditto.
