What is fax2mail
A bash script to accept inbound faxes and forward them (in PDF/EPS/TIFF format) to the desired email addresses. This script links to Asterisk PBX.
The latest version of the fax2mail script can be downloaded from here.
CPAN Prerequisite
For fax2mail to be able to send emails mime-construct requires to be installed.
yum -y install perl cpan libyaml perl-YAML wget http://search.cpan.org/CPAN/authors/id/R/RO/ROSCH/mime-construct-1.11.tar.gz tar xzvf mime-construct-1.11.tar.gz cd mime-construct-1.11 perl Makefile.PL make install
Patch
Install LWP. For a list of CPAN mirrors
perl -MCPAN -e "install Bundle::LWP"
For mime-construct to be configured correctly on a CentOS installation a patch must be run.
perl -MCPAN -e "install Proc::WaitStat" perl -MCPAN -e "install MIME::Types"
NOTE: When the patch is run you will need to press enter a few hundred times.
Testing
mime-construct
You should see:
mime-construct: no recipients specified
Simple email sending
mime-construct --to "your@mail.com" --subject 'hi there' --string "test"
Email with attachment
/usr/bin/mime-construct --header 'Sender: MOR_FAX@TEST.COM' --header 'From: MOR_FAX@TEST.COM' --to your@mail.com --subject 'Email test' --file-attach /var/spool/asterisk/faxes/fax_test.pdf
fax extensions
[prifax]
exten => s,1,GotoIf($["${CALLERID(name)}"="${CALLERID(number)}"]?:3)
same => 2,Set(CALLERID(name)=)
same => 3,AGI(cid-lookup-v4.agi)
same => 4,Set(FAXFILE=/var/spool/asterisk/fax/${UNIQUEID})
same => 5,Answer()
same => 6,Wait(2)
same => 7,ReceiveFAX(${FAXFILE}.tif)
exten => h,1,System(/usr/sbin/fax2mail -f ${FAXFILE} --cid-name "${CALLERID(name)}" --cid-number ${CALLERID(num)})

# File: fax2mail |
# Type: BASH script |
# Summary: fax to E-Mail helper application for asterisk PBX |
# Description: fax2mail is a helper application which sits between |
# asterisk and a MTA. Is is designed to be called by asterisk upon the |
# receipt of a new fax. It will forward the received fax to the email |
# address of choice, and will convert the file the one of several |
# formats. |
# |
#=========================================================================|
# |
# Usage: |
# fax2mail allows these parameters from asterisk as follows: |
# -p = To attach in pdf format (default) |
# -e = To attach in eps format |
# -t = To attach in tif format |
# -f = absolute path to file w/out .tif extension |
# --cid-name <CID Name> = Set CID Name of caller to <CID Name> |
# --cid-number <CID Number> = Set CID Number of caller to <CID Number>|
# --dest-exten <Exten Called> = Used to look up destination info |
# from voicemail.conf. |
# --dest-email <Destination Email> = Used to send teh email to. |
# optional if --dest-exten is provided so that the email address |
# can be looked up in voicemail.conf |
# |
#=========================================================================|
# |
# Examples: |
# fax2mail -f /absolute/path/file |
# file.tif in /absolute/path/ would be coverted to a pdf and sent to |
# the email address specified in the "DEFAULTTO" global variable |
# fax2mail -f /absolute/path/file --dest-exten 100 |
# file.tif in /absolute/path/ would be converted to a pdf and sent to |
# the email address associated with the exten 100 in voicemail.conf |
# fax2mail -t -f /absolute/path/file --dest-email user@domain.tld |
# file.tif in /absolute/path/ would be emailed in tif format to |
# user@domain.tld |
# |
#=========================================================================|
# |
# Astrerisk config: |
# [default] |
# ...Unimportant stuff removed for this... |
# ;Detected fax call |
# exten => fax,1,Goto(fax,s,1) |
# |
# [fax] |
# exten => s,1,Macro(recvfax) |
# exten => h,1,System('/usr/bin/fax2mail --cid-number "${CALLERIDNUM}" |
# --cid-name "${CALLERIDNAME}" --dest-exten "${INIT_EXTEN}" |
# -f "${FAXFILE}"') |
# NOTE: INIT_EXTEN has to be set with something similar to... |
# exten => s,n,Set(INIT_EXTEN=${EXTEN}) |
# |
# [macro-recvfax] |
# ; |
# ; Receive incoming fax macro: |
# ; |
# exten => s,1,Set(FAXFILE=/var/spool/asterisk/fax/${STRFTIME(${EPOCH} |
# ,,%Y%m%M%S)}-${CALLERIDNUM}-${INIT_EXTEN}) |
# exten => s,2,rxfax(${FAXFILE}.tif) |
# |
#=========================================================================|

# Dependencies: |
# This application requires asterisk, ast_fax, app_rxfax, tifflib |
# mime-construct |
