Since this does not occur when the fax machine is turned off it can only 
mean one thing: the fax machine is participating in the Phase B protocol 
exchange.... meaning that both the fax machine and the HylaFAX server 
are answering the same calls.  This won't work.

What's happening is that either 1) the fax machine is answering and is 
also sending these "prologue" frames to the sender and the sender does 
not like getting these "mixed" signals - so it sends DCN, or 2) the fax 
machine itself is signalling DCN because it's answering and noticing 
that it's getting HylaFAX's signals also answering.

Again, both the fax machine and HylaFAX cannot answer simultaneously.  
If you insist on having the fax machine answer calls as a backup, then 
set it to answer after like 5 rings and HylaFAX to answer after 1 or 2.  
If that doesn't work, then you'll need to use a fax modem that "cuts 
off" the pass-through port when it is using the line and then run the 
fax machine off of that pass-through port.
