I can't explain to you exactly what you need to do on your Nortel box, 
but basically what you want is for it to dial the DID digits as DTMF 
after the modem picks up the call and before it bridges the incoming 
call through.

Also, I don't know if your modems support voice (AT+FCLASS=? response 
contains an "8") or IS-101 DTMF detection and reporting from the voice 
mode, but if it does, then in your modem config files you'll want to use 
the "CallIDPattern: SHIELDED_DTMF" option.  Take a look at:

 http://hylafax.sourceforge.net/man/hylafax-config.php

and search for "SHIELDED_DTMF".  There is a sample configuration there.  
Make sure that you set RingsBeforeAnswer to 0 as you'll not be 
fax-answering based on rings any more, but rather based on DTMF digits.  
Basically what you're trying to do is to throw the modem temporarily 
into voice mode when the call is answered, watch for DTMF and collect 
the digits, and then throw it back into fax mode and start the usual 
fax-answering at that point.  The DTMF digits are then passed along to 
faxrcvd and FaxDispatch and you can utilize them from there with 
$CALLIDn from there.
