You haven't posted any logs of the failing attempts, or packet captures 
of the SIP traffic, so it's pretty much impossible for anyone to help 
you debug this (anyone who tried would just be guessing).

Steve did not write res_fax (which where SendFAX and ReceiveFAX come 
from), and there are no 'undocumented' options available for it, because 
it's open source and the source code shows all the options that are 
available.

If you would like to try to figure out what is going on, start by 
posting a *complete* log file from Asterisk for a failed inbound FAX 
attempt, with 'core set debug 10' and 'core set verbose 10' and all 
logger levels (including 'fax') enabled.

Thanks
