我已经设置了NodeJS应用程序(带有node_esl),并将其与部署在Amazon AWS上的Freeswitch服务器的事件套接字层(ESL)连接起来。请参阅以下代码:
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);
});
});
我正在使用以下命令在Freeswitch中录制视频会议,我希望上面的接口能够接收RECORD_START | STOP事件。然而,上述事件从未收到过。
# To start recording
conference <conf_id> recording start
# To stop recording
conference <conf_id> recording stop
以下是我正在录制的会议的Freeswitch个人资料:
<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>
我通过此界面接收了大部分ESL事件,但没有收到RECORD_START | STOP。有什么想法吗?
答案 0 :(得分:0)
我测试了这个,看起来RECORD_START | STOP事件只为record应用程序(可能是record_session应用程序发出。我没有测试过这个),但是没有用于会议录制。
为了排除故障,我从freeswitch命令行运行了fs_cli> /event plain all
,当我运行conference <conf_id> recording start
和conference <conf_id> recording stop
时,这些事件就显示出来了。
这是开始事件:

对于您的节点应用,您可以尝试这样的方法来获得所需内容:
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
});
});
});
