Call-file problem for SendFax()

Postby alias_ebx » Tue Jan 25, 2011 10:35 am


i have a working "Asterisk" and "Digium FAX Driver 1.8.0_1.2.1" running and i am able to receive incoming faxes.
the problem is, that i do not understand yet, how to exactly put the information together to get a working call file.

my channel for outgoing calls is titan0. the technology ist SIP.
so when regulary placing calls i use this syntax: SIP/____DESTINATION_NUMBER____@titan0 which works fine.
with the given configuration i get following errors:

Code: Select all
    -- Attempting call on SIP/____DESTINATION_NUMBER____@titan0 for s@fax-outgoing:1 (Retry 1)

... and ...

Code: Select all
    -- Channel 'SIP/titan0-00000000' sending FAX:
    --    /var/lib/asterisk/fax-outgoing/output.tif

exten => s,n,NoOp(FAXOPT(error) : ${FAXOPT(error)})

Code: Select all

Context: fax-outgoing
Extension: s
Priority: 1
Set: FAXFILE=/var/lib/asterisk/fax-outgoing/output.tif
Set: TIMESTAMP=25/01/11 : 16:40:01

i actually do not completely understand the procedure for sending faxes with FFA...
although i actually know that i have messed up those variable assignments like filename - they are probably redundant: in callfile and in fax-outgoing context. its just temporary sample-copy-paste-code...

how should my call-file look like?

AFAIK, you'd better put the outcall destination inside callfile as follows:
Code: Select all
Channel: SIP/titan0/____DESTINATION_NUMBER____

Your trunk is not supporting Fax traffic, is g711 codecs allow?

Have you verified that the document trying to be queued is a valid tif file that Asterisk agrees with? There is a ghostscript command that you can run for this see below. Basically you have to set parameters on the document that conform with what Asterisk is allowed to send. This is from a small Perl script I wrote a while back.

gs -q -dNOPAUSE -dBATCH -sDEVICE=tiffg4 -sPAPERSIZE=letter -sOutputFile=/tmp/finaltif.tif /tmp/thepdf.pdf

This will have ghostscript convert the file into the format that Asterisk requires for documents to be sent. Hope this helps! :D
