You need to provide a WebRTC-compliant module that handles media, then register it using JsSIP.setWebRTC.
I assume in your case you might want to look at the nomedia-webrtc package.

Sorry, I put it on npm but forgot to actually push it to github. It's there now.

Hi,

Could you please guide me if I am correct in performing the Initialization of JssIP.WebRTC variables

---

Change 1 : I have added the following lines to Jssip.jsas below

---

var JsSIP = (function() {
"use strict";

var JsSIP = {};
var pkg = require('../package.json');

JsSIP.Grammar = require('./Grammar/dist/Grammar.js')(JsSIP);

/Added By Raghav to support the Webrtc stack initialization/

JsSIP.WebRTC = require('./WebRTC.js')(JsSIP);
JsSIP.WebRTC.getUserMedia = require('./WebRTC.js')(JsSIP);
JsSIP.WebRTC.RTCPeerConnection = require('../../nomedia-webrtc/rtc-peer-connection/index.js')(JsSIP);
JsSIP.WebRTC.RTCSessionDescription = require('../../nomedia-webrtc/rtc-session-description/index.js')(JsSIP);

/End of Added By Raghav to support the Webrtc stack initialization/

return JsSIP;
}());

---

Change 2 : I have edited the file WebRTC.js as below

---

module.exports = function(JsSIP) {
var WebRTC;

WebRTC = {};

/_/ Add By Raghav
WebRTC.RTCPeerConnection = JsSIP.global.RTCPeerConnection;
WebRTC.getUserMedia = JsSIP.global.navigator.getUserMedia.bind(navigator);
/_End of Add by Raghav*/

// getUserMedia
if (JsSIP.global.navigator.webkitGetUserMedia) {
WebRTC.getUserMedia = JsSIP.global.navigator.webkitGetUserMedia.bind(navigator);
}
else if (JsSIP.global.navigator.mozGetUserMedia) {
WebRTC.getUserMedia = JsSIP.global.navigator.mozGetUserMedia.bind(navigator);
}
else if (JsSIP.global.navigator.getUserMedia) {
WebRTC.getUserMedia = JsSIP.global.navigator.getUserMedia.bind(navigator);
}

I Hope to eliminate the issue below
/usr/lib/node_modules/jssip-for-node/src/RTCSession/RTCMediaHandler.js:128
this.peerConnection = new JsSIP.WebRTC.RTCPeerConnection({'iceServers': se

But I think I missing something Could you please suggest

1. How can eliminate this error above;
2. Files to edit

I have installed nomedia-webrtc through npm globally

Many thanks for the help in advance

with regards
Raghav

Please have a look at https://github.com/shimaore/node-jsSIPp for how I adapted your code.
