Unable to store recordings in separate channel

问题

How can we store recording in separate audio file when unique users joins a call ?

RecordingChannels : 'dual' is not helping me. Can someone please help ?

function MakeCall(to, completedCallback) {

  // Options and headers for the HTTP request
  var options = {
    host: 'api.twilio.com',
    port: 443,
    path: '/2010-04-01/Accounts/' + process.env.TWILIO_ACCOUNT_SID + '/Calls.json',
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Authorization': 'Basic ' + new Buffer(process.env.TWILIO_ACCOUNT_SID + ':' + process.env.TWILIO_AUTH_TOKEN).toString('base64')
    }
  };

  // Setup the HTTP request and our response
  var req = https.request(options, function (res) {
    res.setEncoding('utf-8');
    // Collect response data as it comes back.
    var responseString = '';
    res.on('data', function (data) {
      responseString += data;
    });
  var body = {
    To: to,
    From: process.env.TWILIO_FROM_NUMBER,
    Url: url,
    Record : true,
    RecordingChannels : 'dual'
  };

So, I feel you've been leaving some bits out of your question. Your last comment suggests you are trying to record each channel of a conference.

As I said in my first comment, you can't record a channel for each member of the conference as that is not supported.

You can do single channel recording, which records an entire conversation or dual channel recording when you set it in the API request to make the first call. But dual channel recording will only record two channels if there are two legs to the call. If you are using <Record> to connect to a conference then it will only record that one leg.

I would request you to work on dual channel recording and reply here only if you have working solution. In My opinion the solution doesn't work.

Your suggestions are of no help so far.
