From README example script: REGISTER ok, CALL nothing happens

[Orion project]

Dunno if it's a bug or else, I cannot see any console log message.
I put the example code in the header, body within and without window.onload with same result,
no call at all. the browser does not report anything to (chrome 101)

but with debug enabled it shows

test.lol:3559 Uncaught TypeError: Cannot read properties of undefined (reading 'cause')

Any clue?

Ok it seems that my pbx needs an ACL to allow media to start.

I modified the example code to show to extend the e object other than e.data

to get some valuable results

    var eventHandlers = {
        'progress':function(e){
            console.log('call is in progress');
        },
        'failed':function(e){
            if(e.data){
                console.log('call failed with cause: '+ e.data.cause);
            }else{
                if(e.cause){
                    alert(e.cause);
                }
            }
        },
        'ended':function(e){
            if(e.data){
                console.log('call ended with cause: '+ e.data.cause);
            }else{
                if(e.cause){
                    alert(e.cause);
                }
            }
        },
        'confirmed':function(e){
            console.log('call confirmed');
        }
    };

sorry for the noise.
