DID to Fax Server

[llam]

Hi, my company is going to upgrade the phone lines from PSTN to PRI. DID will be ordered so the system knows where to direct the phone calls. I would like to do the same thing for incoming fax calls. Rather than relying on the devices that receive the fax, I would like the fax service, which is behind the Norstar MICS, to pick up the DID from Norstar. According to the incoming number, different actions should be taken.

I am looking at FaxMaker.(

I was given a list of supported hardware. (

My questions are:
1. What facility (or modules) should be added to my Norstar MICS system in order to serve the requirements?
2. Which FaxMaker supported hardware works the best with the added module?

TIA!
