IAXModem for SME Server
Introduction
This Howto is for the installation of IAXModem in conjunction with Asterisk, SAIL and HylaFax in order to provide a fax over VOIP solution. It is based on information from various forum posts [1] [2]
Sail and Asterisk Setup
Global Settings
In Global Settings
- Make sure that Late Termination is set to 'No'.
- Make sure that the Autosense FAX Extension is set to a number you want to use for the Fax. You will need this number later.
- The Fax Delay setting defaults to 2 seconds. You may need to adjust this later to make sure faxes get detected before asterisk attempts to terminate somewhere other than the FAX.
Trunklines
For each Trunk under Trunklines that you want to be able to detect incoming Faxes on
- Make sure that the Fax detection tick box is ticked
- Include a Transformation String of '95:' at the beginning
Fax Route
Create a new Route for faxes with dialplan(s) starting with 99.
example: 95X.
and with Paths pointing to the Trunks on which you wish to receive faxes - those with Fax detection ticked as above
Fax Extension
Create a new Extension with the same number as set in the Autosense FAX Extension as above. The Device should be 'IAXModem'.
Once created check the stanza generally conforms to the following and change as necessary:
[2000] type=friend username=FaxModem secret=asterisk host=dynamic qualify=3000 context=internal callerid="Faxmodem" <2000> disallow=all allow=slin
IAXModem
Installation
Download the iaxmodem rpm from Aelintra and install
wget http://sarkpbx.com/sail/iaxmodem/iaxmodem-1.0.0-1.noarch.rpm yum localinstall iaxmodem-1.0.0-1.noarch.rpm
Configuration
Check and edit /etc/iaxmodem/ttyIAX0 as necessary:
device /dev/ttyIAX owner uucp:uucp mode 660 port 4570 refresh 60 server 127.0.0.1 peername 2000 secret asterisk cidname YourCompany cidnumber 0123456789 codec slinear
Check and Run
Check the modem registers with Sail and Asterisk
/usr/local/sbin/iaxmodem ttyIAX
should give an output similar to
Modem started Setting device = '/dev/ttyIAX' Setting owner = 'uucp:uucp' Setting mode = '660' Setting port = 4570 Setting refresh = 60 Setting server = '127.0.0.1' Setting peername = '2000' Setting secret = 'asterisk' Setting cidname = 'YourCompany' Setting cidnumber = '0123456789' Setting codec = slinear Opened pty, slave device: /dev/pts/0 Created /dev/ttyIAX symbolic link Registration completed successfully.
and in an asterisk CLI
--Registered IAX2 '2000' (AUTHENTICATED) at 127.0.0.1:4570
Now
db configuration set iaxmodem service status enabled /etc/rc.d/rc7.d/S93iaxmodem start
HylaFax
Install the smeserver-hylafax contrib. When you run faxsetup, at the end it will ask to continue and run faxaddmodem to setup a modem. Enter 'ttyIAX' as the modem port and continue and set other values as required. The IAXModem should be discovered if it was working OK as above. Do not reboot or start HylaFax yet. Edit /etc/hylafax/etc/config.ttyIAX and add
ModemDialCmd: ATDT95%s
Also check
# make attachments readable RecvFileMode: 0666 LogFileMode: 0666 DeviceMode: 0666 # for shared lines set to 10 RingsBeforeAnswer: 1 # change to suit SpeakerVolume: quiet LocalIdentifier: "YourCompany"
Now if you want you can configure who receives faxes by editing
/etc/hylafax/etc/FaxDispatch
Finally set the modem port in the database
db configuration setprop hylafax port=ttyIAX /sbin/e-smith/expand-template /etc/inittab
Now continue with the contrib setup for Hylafax
Operation
Incoming faxes on a Trunkline with detection enabled should be detected by asterisk. You may need to increase the Fax Detect Delay in Global Settings of SAIL to ensure the fax is detected and routed to the fax extension before the call is routed anywhere else. Once detected the incoming fax should be routed to the Autosense FAX Extension, where IAXModem will answer and pass the fax to Hylafax.
Outgoing faxes emailed to 'user@0123987654.fax' will be sent by Hylafax to IAXModem with a dial string prefixed by 95, for example 950123987654. This will initiate a call in asterisk. The 95 prefix will be recognised as the fax route and the call passed to the relevant outgoing Trunk, where the 95 is stripped off and the real number dialled.
iaxmodem Startup Script
The following is the code for the /etc/rc.d/init.d/iaxmodem script from the current iaxmodem-1.2.0.tar.gz source.
#!/bin/sh
# Startup script for iaxmodem

# chkconfig: 2345 95 05
