Hi mukesh, 

Thanks for the reply.

Can you please guide me how I can implement conference call ?
We have successfully implemented 2 person audio call.

This is my code implementation of 2 persons (1 to 1):

var phone;

var session;

if (configuration.uri && configuration.password) {

    JsSIP.debug.enable('JsSIP:*'); // more detailed debug output

    phone = new JsSIP.UA(configuration);

    phone.on('registrationFailed', function (ev) {

        alert(`SIP Registering with UserName: ${sipUserName}  Password: ${sipUserPassword} on SIP server failed with error: ` + ev.cause);

        configuration.uri = null;

        configuration.password = null;

        updateUI();

    });

    phone.on('newRTCSession', function (ev) {

        var newSession = ev.session;

        if (session) { // hangup any existing call

            session.terminate();

        }

        session = newSession;

        var completeSession = function () {

            session = null;

            updateUI();

        };

        session.on('ended', completeSession);

        session.on('failed', completeSession);

        session.on('accepted', updateUI);

        session.on('confirmed', function () {

            var localStream = session.connection.getLocalStreams()[0];

            var dtmfSender = session.connection.createDTMFSender(localStream.getAudioTracks()[0])

            session.sendDTMF = function (tone) {

                dtmfSender.insertDTMF(tone);

            };

            updateUI();

        });

        session.on('peerconnection', (e) => {

            console.log('peerconnection', e);

            let logError = '';

            const peerconnection = e.peerconnection;

            peerconnection.onaddstream = function (e) {

                console.log('addstream', e);

                // set remote audio stream (to listen to remote audio)

                remoteAudio.srcObject = e.stream;

                remoteAudio.play();

            };

            var remoteStream = new MediaStream();

            console.log(peerconnection.getReceivers());

            peerconnection.getReceivers().forEach(function (receiver) {

                console.log(receiver);

                remoteStream.addTrack(receiver.track);

            });

        });

        if (session.direction === 'incoming') {

            //incomingCallAudio.play();

            if ($('#dndSwitch').is(':checked') == false) {

                document.getElementById('incommingCallAudio').play();

            }

        } else {

            console.log('con', session.connection)

            session.connection.addEventListener('addstream', function (e) {

                //incomingCallAudio.pause();

                remoteAudio.srcObject = e.stream;

                if ($('#dndSwitch').is(':checked') == false) {

                    document.getElementById('incommingCallAudio').pause();

                }

            });

        }

        updateUI();

    });

    phone.start();

}

This code is working fine on audio call with 2 persons.

Can you please guide me how I can implement conference call on it ?

From last 2 weeks, we tried many ways but didn't work and we are stuck on it.

 

Thanks in advance.
