一 asterisk+FreePBX的安装请看freepbx 安装配置教程 for CentOS 5.1 /5.2
二 安装IAXmodem+Hylafax
1.安装Postfix
yum install postfix
2.安装hylafax依赖包
yum install ghostscript sharutils mgetty-voice
ln -s /share/fonts/default/ghostscript/ /usr/share/ghostscript/fonts
3. yum install iaxmodem
或下载iaxmodem源码包：http://ufpr.dl.sourceforge.net/project/iaxmodem/iaxmodem/iaxmodem-1.2.0/iaxmodem-1.2.0.tar.gz（用./build static或者./configure->make编译，将iaxmodem复制到/usr/sbin/）
在asterisk中新建IAX2用户1000密码1000将端口改为4570，用户2000密码2000将端口改为4571
如下：
[1000]
type=friend
setvar=REALCALLERIDNUM=1000
secret=1000
qualify=yes
port=4569
transfer=no
mailbox=1000@default
host=dynamic
dial=IAX2/1000
context=from-internal
callerid=device <1000>
accountcode=
[2000]
type=friend
setvar=REALCALLERIDNUM=1000
secret=2000
qualify=yes
port=4571
transfer=no
mailbox=1000@default
host=dynamic
dial=IAX2/2000
context=from-internal
callerid=device <2000>
accountcode=
创建iaxmodem：ttyIAX0、ttyIAX1的配置文件
mkdir /etc/iaxmodem/
vi /etc/iaxmodem/iaxmodem-cfg.ttyIAX0 内容如下
device /dev/ttyIAX0
owner uucp:uucp
mode 660
port 4570
refresh 60
server 127.0.0.1
peername 1000
secret 1000
codec alaw
vi /etc/iaxmodem/iaxmodem-cfg.ttyIAX0 内容如下
device /dev/ttyIAX1
owner uucp:uucp
mode 660
port 4571
refresh 60
server 127.0.0.1
peername 2000
secret 2000
codec alaw
4. 下载hylafax：http://yum.trixbox.org/centos/5/RPMS/hylafax-4.4.4-1rhel5.i386.rpm
安装：rpm -ivh hylafax-4.4.4-1rhel5.i386.rpm
通过faxsetup或faxaddmodem在/var/spool/hylafax/etc/下新建配置文件config.ttyIAX0、config.ttyIAX1
config.ttyIAX0内容如下：
# $Id: iaxmodem,v 1.1 2006/04/02 23:18:30 darren Exp $
#
# prototype config for the IAXmodem softmodem which uses
# the spandsp soft-DSP library
#
#
CountryCode: 0086
AreaCode: 0311
FAXNumber: 1000
LongDistancePrefix: 1
InternationalPrefix: 011
DialStringRules: etc/dialrules
ServerTracing: 0xFFF
SessionTracing: 0xFFF
RecvFileMode: 0600
LogFileMode: 0600
DeviceMode: 0600
RingsBeforeAnswer: 1
SpeakerVolume: off
GettyArgs: "-h %l dx_%s"
LocalIdentifier: "1000"
TagLineFont: etc/lutRS18.pcf
TagLineFormat: "From %%l|%c|Page %%P of %%T"
MaxRecvPages: 200
#
#
#
# Modem-related stuff: should reflect modem command interface
# and hardware connection/cabling (e.g. flow control).
#
ModemType: Class1 # use this to supply a hint
#
# The modem is taken off-hook during initialization, and then
# placed back on-hook when done to prevent glare.
#
#ModemResetCmds: "ATH1/nAT+VCID=1" # enables CallID display
#ModemReadyCmds: ATH0
Class1AdaptRecvCmd: AT+FAR=1
Class1TMConnectDelay: 400 # counteract quick CONNECT response
Class1RMQueryCmd: "!24,48,72,96" # V.17 fast-train recv doesn't work well
CallIDPattern: "NMBR="
CallIDPattern: "NAME="
CallIDPattern: "ANID="
CallIDPattern: "NDID="
# Uncomment these if you really want them, but you probably don't.
#CallIDPattern: "DATE="
#CallIDPattern: "TIME="
修改config.ttyIAX0、config.ttyIAX1的的属性： chown root:root config.ttyIAX0 config.ttyIAX1
将其他的config* 文件删除
5.在/etc/inittab末尾添加：
IAX0:23:respawn:/usr/sbin/iaxmodem iaxmodem-cfg.ttyIAX0
t0:23:respawn:/usr/sbin/faxgetty ttyIAX0
IAX1:23:respawn:/usr/sbin/iaxmodem iaxmodem-cfg.ttyIAX1
t1:23:respawn:/usr/sbin/faxgetty ttyIAX1
6.reboot
7.在/dev/里有ttyIAX0、ttyIAX1说明iaxmodem加载成功
注册其他用户拨打1000或2000会听到传真的滴滴声。
三 安装Avantfax

#chmod +x avantfax-install
#sh avantfax-install
安装avantfax
下载avantfax-3.1.6：http://ufpr.dl.sourceforge.net/project/avantfax/avantfax/3.1.6/avantfax-3.1.6.tgz
#gunzip avantfax-3.1.6.tgz
#tar avantfax-3.1.6.tar
#cd /anywhere_you_untarred_the_sources/avantfax-2.2.6
#chown -R asterisk:asterisk avantfax
#mv avantfax /var/www/html/
#mysql -uroot -ppassw0rd < create_user.sql
#mysql -uavantfax -pd58fe49 avantfax < create_tables.sql
#cd /var/www/html/avantfax/includes/
#cp -a local_config-example.php local_config.php
#vi local_config.php
and change "$dft_config_lang = "en";" to your language ("it" in my case)
#chmod -R 777 /var/www/html/avantfax/tmp
#chmod -R 777 /var/www/html/avantfax/faxes
#cd /var/spool/hylafax/bin
#mv faxrcvd faxrcvd.old
#mv notify notify.old
#ln -s /var/www/html/avantfax/includes/faxrcvd.php /var/spool/hylafax/bin/faxrcvd
#ln -s /var/www/html/avantfax/includes/notify.php /var/spool/hylafax/bin/notify
#mv /usr/bin/faxcover /usr/bin/faxcover.old
#ln -s /var/www/html/avantfax/includes/faxcover.php /usr/bin/faxcover
#/usr/sbin/faxadduser -a pwd asterisk
#/usr/sbin/faxdeluser localhost
#/usr/sbin/faxdeluser 127.0.0.1
#echo 127.0.0.1 >> /var/spool/hylafax/etc/hosts.hfaxd
#vi /etc/sudoers
and add the following line (all on one line):
asterisk ALL = NOPASSWD: /sbin/reboot, /sbin/halt, /usr/sbin/faxdeluser, /usr/sbin/faxadduser -u * -p * *
#vi /etc/crontab
and add the following 2 lines:
0 * * * * /var/www/html/avantfax/includes/phb.php
0 0 * * * /var/www/html/avantfax/includes/remold.php
6. reboot重启以后打开"http://youipaddress/avantfax",用用户名：admin 密码：password 登陆
（在trixbox中可能出现Error: register_globals must be set to Off in /etc/php.ini，编辑/etc/php.ini，将register_globals = Off、register_long_arrays = Off、register_argc_argv = Off就可以了）
7. 在modem设置中添加ttyIAX0、ttyIAX1
