vline add remote stream for callee fail - webrtc

Question

I am trying to use your api in a custom app with imported users.
Everything works fine (auth_token, login, call initiation) , but when the callee should get a response and add the remotestream nothing happens. no errors get shown in the console.
I would appreciate if someone takes a look at the code and tells me what i m missing.
I tried the vline demo at https://freeofcinema.vline.com and it worked with the same browsers and conditions between the two computers. In my app it is a http , but i tried it also with https, and the same problem came up. This is some simplified code i used to test the api.
var Streams = [];
var Vsession = null;
var Vline = (function(){
var Client;
var authToken;
var service_id = 'freeofcinema';
var profile = null;
var Person;
var Calls = [];
var onMessage = function(event){
//alert('message');
var msg = event.message, sender = msg.getSender();
console.log(sender.getDisplayName() +'sais: '+ msg.getBody());
console.log(event);
}
var onMediaSession = function(event){
console.log(event);
var mediaSession = event.target;
InitSession(mediaSession);
}
function Call(mediaSession) {
mediaSession.
on('change', alert_info);
}
function alert_info(b){
console.log(b);
}
function InitSession(mediaSession){
mediaSession.on('mediaSession:addRemoteStream', function(event) {
alert('addRemoteStream');
});
mediaSession.on('mediaSession:addLocalStream', function(event) {
alert('addLocalStream');
});
mediaSession.on('mediaSession:removeLocalStream mediaSession:removeRemoteStream', function(event) {
console.log('removedStream');
});
Calls.push(new Call(mediaSession));
}
return {
init : function(){
if(profile){
return;
}
profile = {
"displayName" : //some getusrname function...
};
$.post('vtoken.php',{//get auth token
id : Comm.Voip_user().id
},function(data){
authToken = data;
Client = vline.Client.create({
"serviceId": service_id,
"ui" : true
});
Client.on('recv:im', onMessage , this);
Client.on('add:mediaSession', onMediaSession, this);
Client.on('login', function(e) {
Vsession = e.target;
//alert('loged in');
});
Client.login(service_id, profile, authToken);
});
},
getPerson : function(id){//id of user to call
if(Vsession){
Vsession.getPerson(id).
done(function(person){
Person = person;
Vsession.startMedia(id);
});
}
}
}
}());
Thank you for your response.
I tried with one user from the app, and another from the https://freeofcinema.vline.com, and the same problem occured. Also the call (in pending state) gets terminated after a short while..

When passing ui:true when creating the client, you do not have to handle the media sessions yourself. Just comment the line Client.on('add:mediaSession', onMediaSession, this); and it should just work.
