It is not about dial plan.  Your original plan should work if you can get 
Asterisk/Zaptel to do "silent answer" (in priority 2).  Otherwise nothing is 
going to work.  On the other hand, all Brother IntelliFAX support silent 
answer (something they call intelligent ring or the like).  See if your 
machine has an TAD (telephone answering device) port - and old Brother I 
used had this.

If yes, you can enable silent answer on the FAX, then connect your 
X100P/Asterisk to this TAD port.  FAX machines usually monitors for FAX tone 
for 2 rings.  Some machines also cut off ring to TAD before it determines it 
the call is not for FAX; if not, simply program your Asterisk to wait for a 
few seconds before doing anything.  This should give you the same 
functionality.
