Freeswitch ESL

Question

RECORD_START | STOP事件我已經設置了一個NodeJS應用程序（帶有node_esl），並將它連接到部署在Amazon AWS上的Freeswitch服務器的事件套接字層（ESL）。請參見下面的代碼：

var esl = require('modesl'), 
conn = new esl.Connection('SERVER_IP', PORT, 'PASSWORD', function() { 
     conn.api('status', function(res) { 
      //res is an esl.Event instance 
      console.log(res.getBody()); 
     }); 


    conn.subscribe([ 
     'RECORD_START', 
     'RECORD_STOP' 
    ], function(evt) { 
     console.log(evt)  
    }); 

    conn.on('esl::event::RECORD_START::*', function(evt) { 
     console.log(evt); 
    }); 

    conn.on('esl::event::RECORD_STOP::*', function(evt) { 
     console.log(evt); 
    }); 
}); 

我使用下面的命令記錄在FreeSWITCH的視頻會議，我希望上面的接口來接收RECORD_START | STOP事件。然而，所述事件從未收到。

# To start recording 
conference <conf_id> recording start 
# To stop recording 
conference <conf_id> recording stop 

以下是發佈會我記錄FreeSWITCH的輪廓：

<profile name="cp"> 
    <param name="domain" value="$${domain}"/> 
    <param name="rate" value="8000"/> 
    <param name="video-mode" value="transcode"/> 
    <param name="interval" value="20"/> 
    <param name="caller-controls" value="default"/> 
    <param name="energy-level" value="0"/> 
    <param name="conference-flags" value="wait-mod|audio-always|livearray-sync|livearray-json-status"/> 
    <param name="max-members" value="25"/> 
    <param name="sound-prefix" value="/usr/local/freeswitch/conf/sounds/"/> 
    <param name="enter-sound" value="tone_stream://%(200,0,500,600,700)"/> 
    <param name="exit-sound" value="tone_stream://%(500,0,300,200,100,50,25)"/> 
</profile> 

我收到廣大ESL賽事通過這個接口，但是不RECORD_START | STOP。有任何想法嗎？

Answer 1

我測試了這個，它看起來像RECORD_START | STOP事件只適用於record應用程序（可能是record_session應用程序，我沒有測試這個），但不適用於會議記錄。

爲了排除故障，我跑fs_cli> /event plain all從FreeSWITCH的命令行，這些事件都出現了，當我跑conference <conf_id> recording start和conference <conf_id> recording stop。

這裏是啓動事件：

這裏是停止事件：

爲了您的節點的應用程序，你可以嘗試這樣的事情，讓你需要的東西：

var esl = require('modesl'), 
 

 
conn = new esl.Connection('127.0.0.1', 8021, 'ClueCon', function() { 
 
    conn.api('status', function(res) { 
 
    //res is an esl.Event instance 
 
    console.log(res.getBody()); 
 
    }); 
 

 
    conn.subscribe('CUSTOM conference::maintenance', function() { 
 
    conn.on('esl::event::CUSTOM::**', function(evt) { 
 
     console.log(evt); 
 
     // now do something 
 
    }); 
 
    }); 
 
});
