software would have a difficult time making sense of). In other words, unless you ded-

icate a DID to each user who might receive a fax, Asterisk isn’t going to be able to do

much more than send all faxes to a single email address. You could code something in

the dialplan to handle this, though, or have an external cron job or other daemon handle

distributing the received faxes.

A simple dialplan to handle fax to email might look something like this (you will need

the mail program mutt installed on your system):

exten => fax,1,Verbose(3,Incoming fax)

; folder where your incoming faxes will initially be stored

same => n,Set(FAXDEST=/tmp)

; put a timestamp on this call so the resulting file is unique

same => n,Set(tempfax=${STRFTIME(,,%C%y%m%d%H%M)})

same => n,ReceiveFax(${FAXDEST}/${tempfax}.tif)

same => n,Verbose(3,- Fax receipt completed with status: ${FAXSTATUS})

; *** This line should not have any line breaks

same => n,System(echo | mutt -a ${FAXDEST}/${tempfax}

-s "received fax" [email protected])

Obviously, this sample would not be suitable for production (for example, it does not

handle fax failure); however, it would be enough to start prototyping a more fully

featured incoming fax handler.

Fax to PDF

Delivering a fax to a user as a PDF is a popular request. Since PCs, Macs, and Linux

desktops can natively read TIFF files without any conversion required, this isn’t strictly

required. Nevertheless, many people insist on this functionality.

You can use a utility such as ghostscript to perform the conversion.

Fax Detection

You may have a dedicated phone number for receiving faxes. However, with Asterisk,

that is not a requirement. Asterisk has the ability to detect that an incoming call is a

fax and can handle it differently in the dialplan. Fax detection is available for both

DAHDI and SIP channels. To enable it for DAHDI, set the faxdetect option in /etc/

asterisk/chan_dahdi.conf. In most cases, you should set this option to incoming.

Table 19-1 lists the possible values for the faxdetect option in chan_dahdi.conf.
