* listens for fax tones as soon as you Answer() the line. If you Answer
the line before ringing the local lines, it will actually detect fax tones
while in the Dial statement.

I would be interested in how you do fax autodetection.
I don't do anything particularly special, Asterisk just makes it work.
This is using a bog-standard POTS line at home. Here's the relevant
part of my config:
[macro-outsideline]
exten = s,1,LookupCIDName
exten = s,2,SetMusicOnHold(random)
exten = s,3,Dial(${PHONES},13,Ttm)
exten = s,4,Answer
exten = s,5,Goto(outside-ivr,s,1)
[outside-ivr]
; This is the outside IVR
; Playback a We're not home message
; To leave a message for Scott, press 1
; To leave a message for C, press 2
; Otherwise stay on the line.
;
; Also, 3 = main voicemail
; 4 = check voicemail (main)
; 5 = check voicemail
; 6 = DISA (with password)
;
; Check for fax, too
exten = s,1,NoOp
exten = s,2,DigitTimeout(5)
exten = s,3,ResponseTimeout(2)
exten = s,4,Wait(1)
exten = s,5,Background(laird/ivr-greeting)
exten = t,1,VoiceMail(s2201)
exten = t,2,Hangup
; other stuff goes here, but it's not really important
exten = fax,1,Answer
exten = fax,2,Goto(fax,2201,1)
[outside]
exten = s,1,Macro(outsideline)
exten = fax,1,Goto(fax,2201,1)
95% of this isn't important for faxing, but I included it for context.
The big issue is the IVR stuff and the 'fax' extension. Once we get to
the IVR, asterisk is listening for DTMF tones and apparently also fax
tones. If it hears a fax, then it goes to the 'fax' extension. That's
it.

[Asterisk-Users] RxFax/spandsp: file-naming of received faxes
Hi,
after successfully having installed RxFax/SpanDSP and some promising tests
(great piece of software, Steve!) I wonder if it is possible to avoid
overwriting the same tiff file over and over again.
Browsing the sourcecode of app_rxfax.c I found a magic '%d' flag being parsed
out from the argument of rxfax(), but didn't manage to make that work.
extensions.conf:
exten = _3XX,1,rxfax(/tmp/faxfor-${EXTEN}-%d.tif)
always produces filenames like 'faxfor-345-0.tif', so the %d is handled somehow.
My intension is to watch the fax directory for new files by a cron job and email
them to their recipients.
It would be nice to have %d being replaced by a timestamp like 20040328120208 or
simply an incrementing integer and if possible have the calling station id added
to the filename.
Any hints are greatly appreciated.
Thanks a lot,
Jan

Hi Jan,
Try this:
exten = _3XX,1,SetVar(FAXFILE=/tmp/faxfor-${EXTEN}-${TIMESTAMP}.tif)
exten = _3XX,2,rxfax(${FAXFILE})
Good luck,

Or
exten =
_3XX,1,SetVar(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
If you want a unique id, why not use the one that Asterisk provides?
In case anyone's interested, I spent a bit of time on incoming faxes
yesterday, prototyping a DID FAX-type setup. Here are a few snippets,
in case anyone's interested.
[macro-faxreceive]
exten = s,1,SetVar(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
exten = s,2,DBGet(EMAILADDR=extensionemail/${MACRO_EXTEN})
exten = s,3,rxfax(${FAXFILE})
exten = s,103,SetVar([EMAIL PROTECTED])
exten = s,104,Goto(3)
[fax]
exten = 2201,1,Macro(faxreceive)
exten = 2202,1,Macro(faxreceive)
exten = 2203,1,Macro(faxreceive)
exten = h,1,system(/usr/local/sbin/mailfax ${FAXFILE} ${EMAILADDR} \
${CALLERIDNUM} ${CALLERIDNAME})
; I'm using a shared analog line for testing this, so I'm using the fax
; autodetection code to yank faxes out of my IVR and into the 'fax'
; pseudo-extension
[outside]
...
exten = fax,1,Goto(fax,2201,1)
Finally, here's /usr/local/sbin/mailfax:
#!/bin/sh
FAXFILE=$1
RECIPIENT=$2
FAXSENDER=$3
tiff2ps -2eaz -w 8.5 -h 11 $FAXFILE |
ps2pdf - |
mime-construct --to $RECIPIENT --subject Fax from $FAXSENDER
--attachment fax.pdf --type application/pdf --file -
In Debian, tiff2ps comes in libtiff-tools, ps2pdf is part of
Ghostscript, and mime-construct is its own package.
To set the email address associated with each extension, do 'database
put extensionemail EXTEN [EMAIL PROTECTED]'
