It worked, I dare say, flawlessly. Well, as flawlessly as Inter-Tel
worked. Still had to watch out for line error counters, and still had
to reboot it daily (Windows + Inter-Tel equals unstable).

When sending calls into Inter-Tel, the other side, probably asterisk,
masquerades as telco sending in call as PRI.

In the other direction, you configure the lines as OPX, or off-premise
extensions. Just make the extensions match for each line on the PRI
and set your dialplan so you keep things making sense.
