电话会议是一个常用功能，freeswitch当然支持，下面是基本用法：
一、发起会议
| 1 |
conference test bgdial user/1004
|
上面的命令表示，发起1个名为test的会话，同时拨打1004用户，如果该用户接听了，就相当于加入会议。注：如果1004是第1个加入会议的人，此时会议室还没有人，只能听到背景音乐等待其它人加入。
如果再拉1个人进来，即：
| 1 |
conference test bgdial user/1000
|
这时1000与1004，就可以相互听见对方的声音了。
二、查看会议的人员列表
| 1 |
conference test list
|
上面的命令，表示查看会议test的用户列表，结果如下图：
注意：每行最开始的数字，即为用户的member-id，这个很有用，后面会讲到。
三、将某人从会议中踢出
| 1 |
conference test kick 9
|
将member-id为9的用户（即：1004）从会议test中踢出
四、对某人静音/解除静音
| 1 |
conference test mute 10
|
表示在会议test中，对member-id为10的用户静音。如果把mute换成tmute即为解除静音。
五、让某人听不到会议内容
| 1 |
conference test deaf 10
|
表示让member-id为10的用户，听不到test会议的内容，如果deaf换成undeaf即为恢复。
六、结束会议
| 1 |
conference test hup all
|
表示结束会议test，hup即为hangup的缩写
当然，还有其它很多命令，可以在freeswitch控制台下输入conference help查看，下面是完整列表：

这些命令不用死记，遇到新需求时，可以先大概猜名字，然后到最后参考文章链接中搜索，比如：会议中不想再让新人进来来，想锁定本次会议，看着lock好象是干这样的，到官网上看一下解释，就是它！
