You haven't posted any logs of the failing attempts, or packet captures <br />
of the SIP traffic, so it's pretty much impossible for anyone to help <br />
you debug this (anyone who tried would just be guessing).<br />
<br />
Steve did not write res_fax (which where SendFAX and ReceiveFAX come <br />
from), and there are no 'undocumented' options available for it, because <br />
it's open source and the source code shows all the options that are <br />
available.<br />
<br />
If you would like to try to figure out what is going on, start by <br />
posting a *complete* log file from Asterisk for a failed inbound FAX <br />
attempt, with 'core set debug 10' and 'core set verbose 10' and all <br />
logger levels (including 'fax') enabled.<br />
