Right. We talked about this about a month ago, and it would require more
than programming to allow the isdn b channel of 1 pm3 to access the modem
in another pm 3. I would think it would require a BUS extension, something
like a SUPERSTACK setup.

AFAIK, that is how it works. Some people will buy a bare pm 3 JUST for
isdn customers and set up a different phone # to prevent this.

Hrm, sounds like an INTERESTING and possibly plausible idea. Try it!

Dont need to set up separate PRI's. The phone co can set up different
hunts within and/or across PRI's (im told by swbt).

But Id try your modems at the end idea first.
