The audio you posted doesn't seem to come from the call in your log 
file. The audio is very odd, with sections of a FAX called joined 
together in a strange order. The log file is very simple, and tells you 
exactly what went wrong. It says:

        Fax processing not successful - result (10) Far end is not able 
to transmit.

and the reason it says this is because the DIS message from the far end 
says:

        .... ...0= Ready to transmit a fax document (polling): Not set
