因为所在部分主要负责公司客服业务，需要了解freeswich相关内容，所以这里将学习内容记录下。
1：安装freesswich
freeswich是一个实现了软交换协议的开源软件，可以对对接运营上的通话线路，实现拨打电话。
- 安装依赖
yum install -y https://files.freeswitch.org/repo/yum/centos-release/freeswitch-release-repo-0-1.noarch.rpm epel-release yum install -y yum-utils --enablerepo=extras yum install -y yum-plugin-ovl centos-release-scl rpmdevtools yum-utils git wget vim devtoolset-7-gcc* devtoolset-7 libtiff-devel cmake3 libatomic unixODBC unixODBC-devel.x86_64 postgresql-libs postgresql-devel libpqxx-develyum install -y gcc-c++ autoconf automake libtool ncurses-devel zlib-devel libjpeg-devel openssl-devel e2fsprogs-devel sqlite-devel libcurl-devel pcre-devel speex-devel ldns-devel libedit-devel libxml2-devel libyuv-devel libvpx-devel libvpx2* libdb4* libidn-devel unbound-devel libuuid-devel lua-devel libsndfile-devel yasm-devel
- 下载源码并编译
cd /data
git clone -b v1.10.7 https://github.com/signalwire/freeswitch
cd /data/freeswitch
git clone https://github.com/freeswitch/spandsp.git
git clone https://github.com/freeswitch/sofia-sip.git#编译spandsp
cd /data/freeswitch/spandsp
./bootstrap.sh
./configure
make
make install#编译sofia-sip
cd /data/freeswitch/sofia-sip
./bootstrap.sh
./configure
make
make install#添加库的路径到系统
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}
ldconfig# 编译fs
cd /data/freeswitch
./bootstrap.sh
./configure --enable-portable-binary --prefix=/usr/local/freeswitch --with-gnu-ld --with-python --with-openssl --enable-core-odbc-support --enable-zrtp
make
make install
注意：如果报错，找到modules.conf文件，将报错的模块注释掉即可。如
#applications/mod_signalwire #applications/mod_av，具体根据当时的情况看吧，谁报错就注释掉谁。
- 启动

停止命令 ./freeswich -stop
- 查看端口号
会启动好几个端口，各有各的作用。
[root@localhost bin]# netstat -nlp|grep frees

2：安装软电话
模拟真实的电话，客服使用的就是这玩意，从这里 下载，下载后，按照如下配置注意ip改成你自己的：
变为下图就成功了：
此时我们就可以通过freeswich呼叫软电话了通过fs提供的fs_cli工具和originate命令：
[root@localhost bin]# ./fs_cli -H 127.0.0.1 -p ClueCon
