Forward answered call to extension and still stay connected , just like conference

[vaibhaodumore-sdn]

I am new to plivo, please help me out with this one.
I have this requirement like A calls to B. B answers phone and then transfer it C. Transfer to C is working. Now what I need that A, B and C all should be connected at same time, just like conference.

happy to help.

you can use https://github.com/plivo/plivo-examples-node/blob/master/voice/conference/conferenceXML.js to set up a public url (e.g., https://example.com/conference/) then make calls to A, B, and C and set the answer url of the calls to that conference url.

This comment from my another account.
But A and B are already on active call ? Whenever I try to add C, B is getting hang up from the call. I was using transfer call api. I also tried the conference api too, but still A and B are getting hang up as

[cachrisman]

if A and B are on an active call, you need to transfer them using plivo.transfer_call function. See details of params to send in our Call API docs. You need to include legs: 'both', aleg_url, and bleg_url both of which point to your conference url as described in my earlier comment.

Then make a call to C and for the answer_url specify the same conference url as above.

If you still can't figure it out, please post your entire code and describe your call flow from beginning to end and I can help you further.

@cachrisman - I create the business logic behind the app that @vaibhaodumore-sdn is working on and we are still having problems. I will articulate what we're trying to accomplish, what the issue is and @vaibhaodumore-sdn will post the code. Think of the app as a classic call center style application.

Here is what the app should do:

First, Consumer A calls the call center and connects with Phone Agent B. Or, Phone Agent B places an outbound call to Consumer A. Under either scenario, the two parties are connected.

Next, Phone Agent B wishes to transfer the call to Any Person C and remain on the line, forming a 3 person conference call. Any Person C could be 1) an external phone number, 2) an internal extension or 3) a queue.

Finally, Phone Agent B wishes to disconnect himself from the call, leaving Consumer A and Any Person C on the call.

As of right now, we are not able to 1) connect all 3 parties or 2) disconnect Phone Agent B and leave A and C to talk.

Thanks in advance for looking at the code to see what we are missing!

Here is the code I am using, Please have look.

var plivo = require('plivo');

app.use('/transfer', function(req, res) {
   var phone = req.body.phone
    var params = {
        aleg_url: BaseUrl + '/conference?transferTo=' + phone,
        legs: 'both',
        bleg_url: BaseUrl + '/conference?transferTo=' + phone
    };

    var plivoApi = plivo.RestAPI({
        authId: webPhoneDetails.username,
        authToken: webPhoneDetails.password
    });

    plivoApi.transfer_call(params, function(status, response) {
        if (status >= 200 && status < 300) {
            console.log('Successfully made transfer request.');
            console.log('Response:', response);

        } else {
            console.log('Oops! Something went wrong.');
            console.log('Status:', status);
            console.log('Response:', response);
        }
        res.json({ code: "Success" });
    });

})

app.use('/conference', function(req, res) {
    var plivML = plivo.Response();
    var transferTo = req.body.transferTo;
    var params = {method: 'GET'}
    var paSIP = 'sip:' + transferTo + '@phone.plivo.com';
    plivML.addDial(params).addUser(paSIP);

    plivML.addSpeak("You will now be placed into a demo conference.");
    var params = {
        'enterSound' : "beep:2", // Used to play a sound when a member enters the conference
        'record' : "false",
         'startConferenceOnEnter' : "true", 
    };

    var conference_name = "demo"; // Conference Room name
    plivML.addConference(conference_name, params);
    var xml = plivML.toXML();
     res.set('Content-Type', 'text/xml');
     res.(xml);

})

Final xml is:

<Response>
<Dial><User>sip:@phone.plivo.com</User></Dial>
<Speak>You will now be placed into a demo conference.</Speak>
<Conference enterSound="beep:2" record="true" startConferenceOnEnter="true">demo</Conference>
</Response>
