【问题描述】：

我关注了官方文档 (https://freeswitch.org/confluence/display/FREESWITCH/Conference+Add+Call+Example)，但它对我不起作用。

当我给一个人打电话时，他没有加入会议，但是我如何让他加入会议并在我断开电话的情况下保持？

例如我正在尝试如下：

1 - 我和我的其他同事需要 Stackoverflow 专家咨询

2 - 我和我的其他同事加入了一个会议室

3 - 现在我们需要 stackoverflow 程序员给我们 30 分钟的讲座，所以我们给他打电话（我在这里是管理员）

4 - 当我与 stackoverflow 交谈时，会议中没有人听到 stackoverflow 专家。

那么我怎样才能把他带进会议呢？

【解决方案1】：

请参阅 mod_conference 文档中的 bgdial 和 dial。

你在做什么，看起来还不错，需要调试。但是使用conference dial 会更轻松。

【讨论】：

请问如何从 XML 中使用它？
我的问题是我可以从会议呼叫但我无法将那个人连接到会议。
另外，当我断开与他的通话时，他也断开了，想法是抱着他，让他加入会议，然后我必须离开，但他会继续对话。
如果您构建一个我们可以一起查看的测试服务器，那将有所帮助。它需要调试并查看发生了什么。
是的，我很容易找到 :)

【解决方案2】：

您应该使用电话会议，这将使您的目标更容易。

使用 XML dialplan 调用的 Lua 脚本：

function call_to_agent()
    session:execute("conference_set_auto_outcall","user/[user_that_you_want]")
    session:execute("conference","conference_name@default")
end

session:answer()
call_to_agent()
