The following simple JavaScript code creates a JsSIP User Agent instance and makes a SIP call:
var socket = new JsSIP.WebSocketInterface('wss://sip.myhost.com'); var configuration = { sockets : [ socket ], uri : 'sip:[email protected]', password : 'superpassword' }; var ua = new JsSIP.UA(configuration); ua.start(); // Register callbacks to desired call events var eventHandlers = { 'progress': function(e) { console.log('call is in progress'); }, 'failed': function(e) { console.log('call failed with cause: '+ e.data.cause); }, 'ended': function(e) { console.log('call ended with cause: '+ e.data.cause); }, 'confirmed': function(e) { console.log('call confirmed'); } }; var options = { eventHandlers, mediaConstraints: { 'audio': true, 'video': true } }; var session = ua.call('sip:[email protected]', options);
