asterisk - 如何在通话中使用 Asterisk 播放音乐？

Question

我有一个问题：在 Asterisk 脚本中，我通过命令 Dial(SIP/xxx) 执行从 A 到 B 的呼叫。我想在 A 和 B 交谈时播放音乐。

Fuction Dial 仅支持音乐开始通话或结束通话： https ://www.voip-info.org/wiki/view/Asterisk+cmd+Dial

如果你知道，请帮助我。

有 2 种可能的变体

1) 在通话结束前的某个时间拨打命令 L 参数播放文件，带有重复选项

  L(x[:y[:z]]): 
        x - Maximum call time, in milliseconds

        y - Warning time, in milliseconds

        z - Repeat time, in milliseconds
Limit the call to <x> milliseconds. Play a warning when <y> milliseconds
are left. Repeat the warning every <z> milliseconds until time expires.
    This option is affected by the following variables:
        ${LIMIT_PLAYAUDIO_CALLER}: 
            yes
            no
            If set, this variable causes Asterisk to play the
            prompts to the caller.
        ${LIMIT_PLAYAUDIO_CALLEE}: 
            yes
            no
            If set, this variable causes Asterisk to play the
            prompts to the callee.
        ${LIMIT_TIMEOUT_FILE}: 
            filename
            If specified, <filename> specifies the sound prompt
            to play when the timeout is reached. If not set, the time remaining
            will be announced.
        ${LIMIT_CONNECT_FILE}: 
            filename
            If specified, <filename> specifies the sound prompt
            to play when the call begins. If not set, the time remaining will
            be announced.
        ${LIMIT_WARNING_FILE}: 
            filename
            If specified, <filename> specifies the sound prompt
            to play as a warning when time <x> is reached. If not set, the
            time remaining will be announced.
