For analog DID with HylaFAX I think that the only hardware to use is the 
MultiTech MT5634ZBA-DID.

This depends on how you configure the modem.  See the manual.

DTMF, but again, it may be configurable.

It refers to how many digits are in the DID.  Often this is 4.

Wink... but again, I believe that it's configurable.

I guess no.

PRI is different from analog DID.  A PRI will cost you hundreds of 
dollars per month.  An analog DID line will cost you maybe $50.

The MT5634ZBA-DID is the only hardware that I know of that will help you 
here.

Analog DID lines are receive-only.  If you need to use the modem to send 
as well then you'll need a second line for that.  (The modem handles 
both lines.)
