The entire log of the call with the debug all the way up including sip traces would be a good start

sofia profile internal siptrace on
console loglevel debug

edit fax.conf.xml and set verbose to true and restart 

get a pcap of the whole thing.

open an issue on jira and attach everything and report the bug ID here.

So far you have kept that much secret. What you supplied was only the
very last stages of a call log, where Freeswitch seems to be output the
