[Asterisk-Users] Norstar MICS

[David Gomillion]

I am currently working on an Asterisk test system, and will be
presenting a demo to the Board of Directors tomorrow night.  I want to
make sure I have all of my ducks in a row.

The Asterisk system will be used to replace a Norstar MICS.  The
location has two PRI's coming in, with a few hundred DIDs.  I know how
to make * use the DIDs incoming, and I know how Nortel uses the DIDs.
Now for the question: I wish to put * between the telco and the Nortel
PBX.  How do I set up dialing out a PRI from * to the Nortel and sending
the 4 digits so that the legacy phone system knows which extension to
route the call to?

Am I thinking about this wrong?  It seems to me that I need to buy a
4-port T1 card, take in the 2 PRIs on two of the ports, do the * magic,
and output 2 PRIs on the other 2 ports, thereby connecting the Nortel
and * and the P$TN.  Has anyone actually done this?

Can it work?  I really don't want to lie... If I need to present the
plan as replacing the entire system all at once, that's fine, but
they're a lot more likely to sign off if we can do it as a phase-out
instead of a forklift upgrade.

Thanks,
David Gomillion
