如何使用带 mod_conference 的 freeswitch 进行一键通、对讲机 (PTT)

How do I do a Push to Talk, Walkie Talkie (PTT) using freeswitch with mod_conference

我试着用 push 跟它说话。 一个 android sip 客户端和服务器 sip (freeswitch) 我的 mod_conference 有:

文件conference.conf.xml

    <group name="radio">
      <control action="mute" digits="0"/>
      <control action="deaf mute" digits="*"/>
      <control action="energy up" digits="9"/>
      <control action="energy equ" digits="8"/>
      <control action="energy dn" digits="7"/>

现在我不知道在这一刻使用这个文件 radio.pl 我尝试使用 android sip 的 sip 客户端并且在会议中都成功了,但现在我想配置一个谈话和大家听着,在这一刻所有的谈话和所有的倾听,拜托我需要帮助

谢谢

我目前正在尝试完成相同的任务。我做的一件事是使用会议成员标志将所有成员静音。当按下 ptt 按钮时,它将向会议发送 dtmf "unmute" 事件。

唯一的问题是没有阻止当前在会议中的其他成员也与另一个成员同时按下 ptt 按钮,因此会议中有 2 个成员同时发言,这是你不想要的
