You can trick their machine into sending tones. The following code with
send tones that a "terminating" fax machine would normally respond with.
This will even force really old G2 fax machines to respond.
indications.conf:
faxrec = !2100/2600,!0/10,!1850/2600
[custom-fax-did]
exten => s,1,SetVar(FAXFILE=/var/spool/asterisk/fax/${UNIQUEID}.tif)
exten => s,2,SetVar(EMAILADDR=${FAX_RX_EMAIL})
exten => s,3,SetCallerID(<${FROM_DID}>)
exten => s,4,Answer
exten => s,5,Playtones(faxrec)
exten => s,6,Wait(6)
exten => s,7,rxfax(${FAXFILE})
exten => s,8,system(tiff2pdf -p letter ${FAXFILE} -o ${FAXFILE}.pdf)
exten => s,9,system(mime-construct --to ${EMAILADDR} --subject "Fax DID
${CALLERIDNUM}" --attachment ${CALLERIDNUM}.pdf --type
application/pdf --file ${FAXFILE}.pdf)
exten => s,10,system(rm ${FAXFILE} ${FAXFILE}.pdf)
exten => s,11,Hangup

It all boils down to this: If they don't send a tone I won't get the fax.
And I certainly understand this approach. However, there are some
situations where this is simply not suitable - where missing a fax costs
money. Take, for example, the real estate industry where a fickle
customer (isn't everyone fickle when dealing with real estate?) can be
surveying mortgage quotes (frequently done by fax) and if you don't get
their faxed authorization to pull their credit report and then you call
them two days later to find out where it is ... well that customer may
have already signed with another lender... and that just cost that agent
1-2% of the mortgage price (so that lost fax easily cost $2000 in lost
opportunity).
