Getting CallSID for Twilio Softphone / Twilio.js i

问题:

I have created an application using https://www.twilio.com/docs/howto/twilio-client-browser-soft-phone as the template. I am trying to log the CallSid for incoming and outgoing calls so that I can tag calls locally and use the Callsid to link between my local data and twilio's call store. I am able to get the CallSid for incoming calls easily with:

Twilio.Device.incoming(function (conn) {
   if (confirm('Accept incoming call from ' + conn.parameters.From + '?')){
      connection=conn;
      conn.accept();
      callsid = connection.parameters.CallSid;
   }
   else {
      connection=conn;
      conn.reject();
   }
});

However, I can't seem to get it from any outgoing call initiated by the softphone. I have tried here:

$("#call").click(function() {
   params = { "tocall" : $('#tocall').val()};
   connection = Twilio.Device.connect(params);
   callsid = connection.parameters.CallSid;
});

and here:

Twilio.Device.connect(function (conn) {
   $('#status').text("Successfully established call");
   toggleCallStatus();
   callsid = connection.parameters.CallSid;
   // And also tried
  callsid = conn.parameters.CallSid;
});

However, both of these return undefined. I saw on https://www.twilio.com/docs/client/connection that the CallSid is set in the Outgoing .parameters towards the bottom of the page, so I assume it should be available in one of these function calls.

Is the CallSid available for calls originated by the client? And if so, where/how do I access it?

回答1:

Well, the connection.parameters you are getting is empty and you can check this by plugging console.dir(connection)

However, the reason is : Twilio does not populate parameters on outgoing connections for twilio.js V: 1.1 only for incoming connection so please use twilio.js 1.2 to make it works :)

Using TwilioJS 1.2 as recommended by adnanonline is the correct option. This version sets all appropriate parameters for you to access.
