问题描述：fs_cli无法连接FreeSWITCH服务器

解决方法：https://freeswitch.org/confluence/display/FREESWITCH/mod_event_socket

Configuration

First enable the mod_event_socket module in modules.conf.xml (in a system compiled from source this is located in /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml)

By default the module is enabled but restricted to localhost by the settings specified below.

The module settings can be changed in the event_socket.conf.xml file (in a system compiled from source this is located in /usr/local/freeswitch/conf/autoload_configs/event_socket.conf.xml):

<configuration name="event_socket.conf" description="Socket Client">
  <settings>
    <param name="listen-ip" value="127.0.0.1"/>
    <param name="listen-port" value="8021"/>
    <param name="password" value="ClueCon"/>
  </settings>
</configuration>

The default settings allow socket connections only from the local host. To allow connections from any host on the network, use 0.0.0.0 instead of the default 127.0.0.1:

<configuration name="event_socket.conf" description="Socket Client">
  <settings>
    <!-- Allow socket connections from any host -->
    <param name="listen-ip" value="0.0.0.0"/>
    <param name="listen-port" value="8021"/>
    <param name="password" value="ClueCon"/>
  </settings>
</configuration>
最后重启freeswitch,进入到bin目录中，[root@root bin]# fs_cli -H 127.0.0.1 -P 8021 -p ****
