Asterisk Fax to email
Asterisk Fax to email example
Description
This is a working example of a fax to email implementation for asterisk
Packages used
- Spandsp (receive faxes)
- Bash (script)
- sendEmail (sending emails) - http://caspian.dotconf.net/menu/Software/SendEmail/
Overview
The idea is quite simple. I needed a fax server that could send an email with attachment when a fax is received. Fax comes in on dedicated extensions (I am not doing any fax detection as I am using SIP only) , using the dialplan the fax is received and saves to a tiff file. The email address, To name and the hosting companys name is stored in the asterisk db using database put from the management console.
These are retrieved when the call is received and passed along to a bash script which generates an email and sends it with the fax as an attachment using sendEmail (opensource per script)
Configuration files
Extensions.conf
[macro-faxreceive]
exten => s,1,SetVar(FAXFILE=/var/spool/asterisk/fax/${CALLEDFAX}/${UNIQUEID})
exten => s,2,DBGet(EXTEMAIL=${MACRO_EXTEN}/xEmail)
exten => s,3,NoOP()
exten => s,4,DBGet(EXTNAME=${MACRO_EXTEN}/xName)
exten => s,5,NoOP()
exten => s,6,DBGet(EXTCOMPANY=${MACRO_EXTEN}/xCompany)
exten => s,7,rxfax(${FAXFILE}.tif)
exten => s,103,SetVar(EXTMAIL=fax@company.com)
