webRTC настройка

купил ключ для webRTC, подскажите, чтобы клиенты общались на сайте через него, нужно устанавливать сервак? или можно как-то безе сервака на виртуальном хостинге его запустить?

<div class="web-box">
   <div id="TeacherWebRTC" style="width:320px;height:240px;border: 1px solid"></div>
   <input type="button" value="start" onClick="startTeacher()"/>
   <p id="status"></p>
</div>

//Teacher webRTC

var TeacherWebRTC;
function initTeacher(){
    Flashphoner.init();
    TeacherWebRTC = document.getElementById("TeacherWebRTC");
}

    Flashphoner.createSession({urlServer: "wss://wcs5-eu.flashphoner.com:8443"}).on(Flashphoner.constants.SESSION_STATUS.ESTABLISHED, function (session) {
        //session connected, start streaming
        startStreamingTeacher(session);
    }).on(Flashphoner.constants.SESSION_STATUS.DISCONNECTED, function () {
