     var options = {

                     media: {
                              constraints: {
                                             audio: true,
                                             video: false,
                                           },
                              render: {
                                        remote: {
                                                   audio: document.getElementById('remoteAudio')
                                                },

                                        local:  {
                                                   audio: document.getElementById('localAudio')
                                                }
                                      }
                           }
    };



    function onAccepted ()
    {
        alert("Call Connected");
    }

    function onDisconnected ()
    {
        alert("Call Terminated");
    }


    //makes the call
    session = userAgent.invite('1000', options);
    session.on('accepted', onAccepted);
    //session.on('disconnected', onDisconnected);

  }

)();

thanks very much to all!!!

Answer 1

I assume that you have installed and running a FreeSwitch instance. In the conf file that defines the sockets for listening you need to uncomment the ws and wss ports for listening. This should get the instance listening for WebSocket messages from the sip.js.

<param name="ws-binding"  value=":80"/>
<param name="wss-binding"  value=":443"/>
