I'm a little new to the Mitel setup, but things look ok. I've got a T1 connected from the Mitel to a Nortel Option 81c. When I dial the access code on the Nortel to hit the T1 to the Mitel, I do indeed get dialtone from the Mitel, but when I dial any extention on the mitel, I get reorder. If I setup vacant number re-routing on the Mitel, then any number I dial goes to the vacant number where I rerouted to, so apparently it is seeing the digits. I have things setup for 4 digit extention numbers, and it is waiting for all 4 digits before giving me reorder. If the call gets directed to the vacant number re-route, I can answer it, and the speech path sounds fine.

So I'm guessing I'm missing something somewhere.
