如何在通話期間使用Asterisk播放音樂？

Question

我有一個問題： 在星號腳本中，我通過命令撥號（SIP/xxx）執行從A到B的呼叫。 我想在與B

函數的恆等式撥打說話只支持音樂開始通話或結束通話播放音樂： https://www.voip-info.org/wiki/view/Asterisk+cmd+Dial

請幫助我，如果你知道的。

有2點可能的變體

1）撥號命令大號PARAM播放文件，在通話結束前一段時間，有重複選項

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.
