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

#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

#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
