I don't understand your goal. You want to send or receive fax?

On our side, dialplan very simplified on incoming calls (receive fax):

. in CLI> fax show settings ; output FAX For Asterisk Settings: blabla
. Set(FAXOPT(faxdetect)=yes); or faxdetect=yes in sip.conf
. Answer()
; if a fax is detected, go to fax extension
. exten => fax,n,ReceiveFAX(${FAXPATHTOFILE}/${FAXFILE},fs)

and done.
