前几天入手Sangoma的A200语音卡，在CentOS下进行配置，使用FreeSwitch。由于网络上大部分人不是很熟悉这个东西，所以都会选择Asterisk作为系统。
以下是本人配置FreeSwitch经历，
在livejournal.com找到一片相关的配置文章。
FreeTDM seems to be replacing OpenZAP now. Following is a quick FreeTDM-based setup to use FreeSWITCH with a Sangoma FXO/FXS card, B600.
We start with minimal CentOS 5.5 install, all options unchecked. After the install is finished,
yum -y update
reboot
yum -y install autoconf automake make gcc gcc-c++ bison flex libtool kernel-devel libjpeg-devel libtermcap-devel libogg-devel libvorbis-devel nano ncurses-devel ntp mc wget
remove most 32-bit packages
yum -y remove glibc.i686
remove the rest of i386 packages
yum list installed | grep i386
service iptables save
service iptables stop
chkconfig iptables off
service ip6tables save
service ipt6ables stop
chkconfig ip6tables off
mcedit /etc/selinux/config
change
SELINUX=enforcing
to
SELINUX=disabled
chkconfig ntpd on
ntpdate pool.ntp.org
reboot
cd /usr/src
wget ftp://ftp.sangoma.com/linux/current_wanpipe/wanpipe-3.5.17.tgz
tar xfz wanpipe-*.tgz
cd wanpipe-*
make freetdm
make install
wanrouter hwprobe verbose
cd /usr/src
wget http://files.freeswitch.org/freeswitch-snapshot.tar.gz
tar xfz freeswitch-snapshot.tar.gz
cd freeswitch-snapshot
./bootstrap.sh
./configure
mcedit modules.conf
uncomment ../../libs/freetdm/mod_freetdm (I also uncommented mod_flite, mod_spandsp, mod_shout, mod_pocketshpinx)
make all install
make samples && make cd-sounds-install && make cd-moh-install
/usr/sbin/wancfg_fs
mcedit /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml
add <load module="mod_freetdm"/> (should be in the same section as mod_openzap)
(Again, look for mod_flite, mod_spandsp, mod_shout, mod_pocketshpinx)
Create FreeSwitch start/stop script:
nano /etc/init.d/freeswitch
Put the following into the file (starting from "#! /bin/sh" and up to "exit $RETVAL"):
#! /bin/sh
#
# freeswitch: Starts the freeswitch Daemon
#
# chkconfig: 345 96 02
# processname: freeswitch
# description: Freeswitch fedora init script \
# config:
# Author: gled
# Source function library.

return 0
}

do_start() {
do_setlimits
$DAEMON -nc
RETVAL=$?
if [ $RETVAL = 0 ]; then
success $"$base startup"
else
failure $"$base startup"
fi
echo
return $RETVAL
}
do_stop() {
$DAEMON -stop
RETVAL=$?
[ $RETVAL = 0 ] && success $"$base shutdown" || failure $"$base shutdown"
rm -f $LOCKFILE
echo
return $RETVAL
}
# See how we were called.
case "$1" in
start)
do_start

stop)
do_stop

restart)
do_stop
echo "Waiting for daemon to exit…"
sleep 5
do_start
;;
*)
echo $"Usage: $0 {start|stop}"
exit 2
;;
esac
exit $RETVAL
Set attributes:
chmod a+x /etc/init.d/freeswitch
Set startup:
chkconfig –add freeswitch
chkconfig freeswitch on
useradd freeswitch
groupadd freeswitch
chown -R freeswitch:freeswitch /usr/local/freeswitch
mcedit /etc/group
Change the line:
freeswitch:x:500
to:
freeswitch:x:500:freeswitch
mcedit /root/.bash_profile
set PATH variable to:
PATH=$PATH:$HOME/bin:/usr/local/freeswitch/bin
mcedit /usr/local/freeswitch/conf/vars.xml
set global_codec_prefs to allow video, adding H263 and H264 codecs:
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM,H263,H264"/>
reboot
do the tests with X-Lite softphone
check using fs_cli command
issue ftdm list and ftdm dump commands while in fs_cli to see spans and channels
!!! for dialplan you need to use span_id and chan_id, not physical_span_id, and not physical_chan_id !!!
close fs_cli with "…" (ellipsis)
Here is the autogenerated freetdm.conf.xml with some additions I’ve made:

以上是一个老外的日记。
配置完成后发现一些问题，Wanpipe虽然模块启动了，但相关协议没有加载，查看log找到问题，wanpipeX.conf 没有这个文件。
找到Wanpipe的源文件，执行./Setup install 选择TDM Install，系统会询问一些诸如linux-Kernel位置的问题，默认按Enter继续，执行到最后安装成功，会自动检测协议和当前模块，生成自动启动脚本。
执行wancfg进入图形化的配置界面。根据界面提示很容易的就可以创建wanpipe1.conf文件，这样wanpipe模块在启动之后就可以自动加载wanpipeX.conf文件，同样，在Back到wancfg的主配置界面可以继续配置wanpipe2.conf。
