fs_cli是FreeSWITCH的一个客户端连接程序，可以方便地查看运行情况，并对其进行控制。若在本机使用默认配置，可直接启动fs_cli；否则需要携带参数（以连接运行在192.168.1.100上的FreeSWITCH为例）：
启动一个命令行窗口，通过help可以查看操作命令；
fs_cli.exe -H 192.168.1.100 -P 8021 -p NewPSW
fs_cli也可执行一条指定的命令（如获取版本信息）：
fs_cli.exe -H 192.168.1.100 -P 8021 -p NewPSW -x "version"
以下‘Console窗口‘是指通过命令行启动（不用nc参数）时的显示与控制界面。
退出操作
退出fs_cli（保持FreeSWITCH运行）：
/quit
/bye
/exit
...：三个点，若在‘Console窗口‘中为退出FreeSWITCH；
Linux可通过ctrl+D快捷键；
退出FreeSWITCH：
shutdown
日志与显示操作
设定显示日志级别
通过console loglevel设定显示级别（fs_cli和‘Console窗口‘中都可以）：
debug,info,notice,warning,err,crit,alert：7个级别
1~7： 对应上面7个级别（7为debug，1为alert）
0：关闭所有输出（console loglevel 0）；
fsctl loglevel <level>：设定指定日志级别；
/log：默认为debug或指定的级别（与loglevel相同）；
/nolog：关闭日志；
sofia profile internal siptrace on/off：开启或关闭SIP消息跟踪功能。

fsctl debug_level [level]：设定日志记录级别（影响日志记录、console输出等）
0 - fatal errors, panic
1 - critical errors, minimal progress at subsystem level
2 - non-critical errors
3 - warnings, progress messages
5 - signaling protocol actions (incoming packets, ...)
7 - media protocol actions (incoming packets, ...)
9 - entering/exiting functions, very verbatim progress
fsctl hupall <clearing_type> dialed_ext <extension>：关闭所有指定呼叫，如：fsctl hupall normal_clearing dialed_ext 1000
fsctl shutdown [asap|asap restart|cancel|elegant|now|restart|restart asap|restart elegant]
cancel - discontinue a previous shutdown request.
elegant - wait for all traffic to stop, while allowing new traffic.
asap - wait for all traffic to stop, but deny new traffic.
now - shutdown FreeSWITCH immediately.
restart - restart FreeSWITCH immediately following the shutdown.
通话相关命令简介
查看注册用户：
sofia status/xmlstatus profile internal reg [1006]
show registrations
删除注册用户：sofia profile internal flush_inbound_reg <用户id>
查看通话通道：show channels [like 1006@] as xml
呼叫（1.6版本下，要带absolute_codec_string='PCMA'，否则可能是视频呼叫，然后编码失败）：
originate user/1011 &bridge(user/1013)
originate user/1006 &bridge(sofia/external/5001@192.168.6.90)
originate user/1011 &playback(rec1011.wav)
originate user/1012 &conference(3001)
originate user/1011 &echo
关闭所有指定呼叫：hupall <cause> [<variable> <value>]
hupall normal_clearing foo bar：关闭所有通道变量foo=bar的channel
加入会议：
conference 3001 dial {absolute_codec_string='PCMA@20i'}user/1013
conference 3001 dial sofia/external/5001@192.168.6.90
列出所有会议：conference list
呼叫中心：
查看Agent：callcenter_config agent list
查看队列：callcenter_config queue list
顺振：originate user/1006 &bridge(user/1011|user/1012)
同振：originate user/1006 &bridge(user/1011,user/1012)
添加通道变量：originate {origination_caller_id_number=8888,ignore_early_media=true,xugd-wavfile=notice.wav,absolute_codec_string=PCMA}user/1018 &lua(voiceNotify.lua)
重新加载配置：
reloadxml：重新一般配置修改（拨号计划、用户等）
