1，关于FreeSwitch
FreeSWITCH 是一个电话的软交换解决方案，包括一个软电话和软交换机用以提供语音和聊天的产品驱动。FreeSWITCH 可以用作交换机引擎、PBX、多媒体网关以及多媒体服务器等。
FreeSWITCH 支持多种通讯技术标准，包括 SIP, H.323, IAX2 以及 GoogleTalk ，可以方便的与其他开源的PBX系统进行对接，例如 sipX, OpenPBX, Bayonne, YATE 或者 Asterisk.
FreeSWITCH 支持许多高级的 SIP 特性，例如 presence/BLF/SLA 、TCP TLS 和 sRTP，它还可以用来作为类似于 SBC (Session Border Controller) 的透明代理。

2，安装
代码迁移过，不在github了。操作系统式centos6，（centos7 操作系统也类似）
https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse
centos6 安装
https://freeswitch.org/confluence/display/FREESWITCH/CentOS+6
首先安装依赖：
yum install git gcc-c++ autoconf automake libtool wget python ncurses-devel zlib-devel libjpeg-devel openssl-devel e2fsprogs-devel sqlite-devel libcurl-devel pcre-devel speex-devel ldns-devel libedit-devel这里遇到一个问题，不能直接下载master代码，编译不过去，依赖一个libyuv库。使用1.4版本进行编译。
git clone -b v1.4 https://freeswitch.org/stash/scm/fs/freeswitch.git
# The -j argument spawns multiple threads to speed the build process
./bootstrap.sh -j
./configure -C
make && make install
make sounds-install
make moh-install安装成功：
---------------------------------------------------------------------- Libraries have been installed in: /usr/local/freeswitch/mod If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl,-rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to `/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. ----------------------------------------------------------------------

增加系统服务，并启动
#拷贝centos6 服务文件
cp build/freeswitch.init.redhat /etc/init.d/freeswitch
chmod 750 /etc/init.d/freeswitch
chkconfig --add freeswitch
chkconfig --levels 35 freeswitch on
#增加用户
useradd --system --home-dir /usr/local/freeswitch -G daemon freeswitch
#设置权限
chown -R freeswitch:daemon /usr/local/freeswitch/
chmod -R 770 /usr/local/freeswitch/
chmod -R 750 /usr/local/freeswitch/bin/*
#创建run目录
mkdir /var/run/freeswitch
chown -R freeswitch:daemon v1.4
#配置二进制文件
ln -s /usr/local/freeswitch/bin/freeswitch /usr/bin/
#启动服务
service freeswitch start4，安装客户端
客户端使用x-lite。下载地址：
http://www.counterpath.com/x-lite-download/
启动后配置下服务器，freeswitch默认注册了20个账号，从1000-1019，默认密码都是1234。
配置信息，假设服务器地址是 192.168.1.100。
同样在另外一个电脑注册1001，然后就可以进行拨号了。
5，总结

freeSwitch还是非常好用的，只需要编译下，配置服务就行。
开源的需要研究透彻，主要的代码是用c写的，支持lua扩展，freeswitch支持很多功能还需要仔细研究。
