Hello.
I've been trying to setup Free Fax for Asterisk on a Debian machine with Asterisk 1.8. I have managed to register and installed the Digium modules. Sending and receiving through it have resulted in failure. The output of fax show capabilities is:
Registered FAX Technology Modules:

Type : DIGIUM
Description : Digium FAX Driver
Capabilities : SEND RECEIVE T.38 G.711 MULTI-DOC

1 registered modules

We have a fax blackbox through which I'm trying to send faxes to the Asterisk server. Every time that I send a fax I get a timeout error. Been tinkering with the settings and whatnot to get it working.



The extension to receive fax:
exten => recvfax,1,Verbose(2,Receiving fax)
same => n,Set(FAXDEST=/tmp/fax)
same => n,Set(tempfax=${STRFTIME(,,%C%y%m%d%H%M)})
same => n,Wait(
same => n,ReceiveFax(${FAXDEST}/${tempfax}.tiff,f,d)
It's without most of the tinkering I've done, which are: setting ecm to no, tweaking the min/max rate and other things.

Also, because the fax machine can't print (half broken), we receive our faxes through a fax to email service we have subscribed to, so the tests for sending have that one as a destination.

The extension to send fax:
exten => sendfax,1,Verbose(2,Sending fax)
same => n,Set(faxlocation=/tmp)
same => n,Set(faxfile=fax.tiff)
same => n,Set(FAXOPT(headerinfo)=Testing FAX)
same => n,Set(FAXOPT(localstationid)=123456)
same => n,SendFax(${faxlocation}/${faxfile},d)
same => n,Verbose(2, Fax Status: ${FAXOPT(error)})
I did the exact same thing, and tried sending from both a SIP channel and a DAHDI line. The weird thing is that when I am sending through Asterisk I get, as a response to fax, a recorded message from the telco. Sending through the same line with the fax machine works perfectly.

Any advice and help is welcome.

Hello;
Just taking a quick glance at it, I think you have a syntax error in your dial plan. Instead of ReceiveFax(${FAXDEST}/${tempfax}.tiff,f,d, shouldn't it be ReceiveFax(${FAXDEST}/${tempfax}.tiff,fd) with no comma between the f and d options?
Regards;
John

It seems to me that I installed it.

Also, @John, there indeed seemed to be a syntax mistake, but Asterisk never complained, so I didn't notice it. Unfortunately, even after correcting it the fax exhibits the same behaviour.
