twilio 通过 nodejs 仅转录应答呼叫？

Question

我找到了一个属性 record-on-answer，我正在尝试将其集成到我的 twiml 响应中，但它不起作用。我试图只记录用户回答的时间。 就像我当前的录音有 5 秒的“您的电话无法转接”一样。然后记录了5秒的沉默。然后是实际连接时的呼叫，时间为 26 秒并正确记录。我只想要第三次录音的 26 秒。如果我用普通电话打电话，我永远不会听到“您的电话无法转移”。

我将如何实现这一目标？

这是我的代码：然后是请求正文。如果 twilio 的任何人可以帮助解决这个编码问题，我将非常感激，因为我非常沮丧。我尝试过启用双声道和单声道录制。 敲击键盘

Answer 1

这里是 Twilio 开发者宣传员。

我认为您可能需要添加一个action attribute for your <Record>。如果您未在 action 属性中包含 URL，则 Twilio 在完成录制后将不会完成调用，它将再次重定向到相同的操作并再次开始尝试录制。

我建议将您的 /sendT 方法更新为以下内容：

app.post('/sendT', urlencodedParser, function (req, res) {
  console.log(req.body);
  var rt = new VoiceResponse();
  rt.record({
    recordingChannels: 'dual',
    recordOnAnswer: true,
    transcribe: true,
    transcribeCallback: 'http://www.REMOVED.com/rT',
    action: 'http://www.REMOVED.com/recorded'
  });
  res.status(200);
  res.send(rt.toString());
  console.log(' finish sendt')
})//end post

然后再添加一个以<Hangup> 回复的/recorded 端点

app.post('/recorded', urlencodedParser, function (req, res) {
  var rt = new VoiceResponse();
  rt.hangup();
  res.status(200);
  res.send(rt.toString());
});

这应该会阻止您收到额外的转录消息。
