If I had a separate line/DID then all this would not be a problem and I 
could just connect it to the fax extension.  Where we are we have the 
single pstn line for voice calls but my wife needs to receive some faxes 
from her boss now and then.  So I thought it would be a simple thing to 
add fax reception to Asterisk/freePBX....

 From all my experimentation today I would say that selecting Zap fax 
detection does NOT work.   The closest thing to working is using the 
NVfax detection and setting the fax destination in the incoming route.  
Then it seems to recognize the incoming fax and not ring the phones but 
it fails dismally at connecting to the fax extension and instead 
continues to deliver a ring to the caller.  If I could figure out how to 
get freePBX to do a Dail(IAX2/3999) when it detects a fax instead of  
the PlayTones() business I'm sure it would be just fine.

-- Starting simple switch on 'Zap/1-1'
   -- Executing Set("Zap/1-1", "FROM_DID=s") in new stack
   -- Executing Set("Zap/1-1", "FAX_RX=3999") in new stack
   -- Executing Answer("Zap/1-1", "") in new stack
   -- Executing PlayTones("Zap/1-1", "ring") in new stack
 == Spawn extension (from-pstn, s, 5) exited non-zero on 'Zap/1-1'
   -- Hungup 'Zap/1-1'

I did find this http://aussievoip.com.au/wiki/index.php?page=DM-Fax but 
it seems to reference an older version of freePBX than what I have 
(2.1.1) and the old/new code is considerably different.
