Trying to register automatically with the webserver if webserver connection is lost

[sumantasen]

Hi All,

I am trying to implementation some sort of automatic reregistration when the websocket is closed.

.

When websocket is getting closed, we are getting callback on onclose() in qoffeesip.js

Now we are triggering one event in webphone.js. There we are able to create the user object again and trying to register

However, the next event is not getting triggered if the webserver is till down.

Here is what I have done in webphone.js

UI.prototype.renderWebsocketClosed = function(message) { console.log("WebSocket is closed now, try re-register");

 //Register again.
 var line, onlyAudio, onopen, server, serverRE, sipServer, stunServer, turnServer, _ref1,
      _this = this;

            window.autoanswering = $("#auto-answer").is(":checked");

    $("#pass-reg").val("123");
    $("#server-reg").val("ws://x.x.x.x:5082");
    $("#only-audio").attr("checked", false);
    $("#stun-server").val("");
    $("#stun-server").val("");
    $("#turn-server-credential").val("");

    User.create({
      user: $("#user-reg").val(),
      password: $("#pass-reg").val(),
      sipServer: $("#server-reg").val(),
      audioSession: $("#only-audio").is(":checked"),
      stunServer: $("#stun-server").val(),
      turnServer: $("#stun-server").val(),
      turnCredential: $("#turn-server-credential").val()
    });

    _ref1 = $("#user-reg").val().split("@"), this.register.ext = _ref1[0], this.register.domain = _ref1[1];
    this.register.pass = $("#pass-reg").val() || this.register.ext;
    server = $("#server-reg").val();
    onlyAudio = $("#only-audio").is(":checked");
    stunServer = {
      url: "stun:" + $("#stun-server").val()
    };
    turnServer = {
      url: "turn:" + $("#turn-server").val(),
      credential: $("#turn-server-credential").val()
    };
    if (stunServer.url === "stun:") {
      stunServer = {
        //"url": "stun:204.236.188.164" //stun.1.google.com
        "url": "stun:173.194.76.127:19302" //stun.1.google.com

      };
    }
    serverRE = /(wss?):\/\/(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})(\:(\d{2,5}))?((\/\w+)*)/;
    line = serverRE.exec(server);
    sipServer = {};
    if (line != null) {
      sipServer.transport = line[1];
      sipServer.ip = line[2];
      sipServer.port = line[4];
      sipServer.path = line[5] || "";
    } else {
      sipServer.ip = "x.x.x.x";
      sipServer.port = "5082";
      sipServer.path = "";
      sipServer.transport = "ws";
    }
    onopen = function() {
      _this.api.on("new-state", _this.newState);
      _this.api.on("instant-message", _this.renderInstantMessage);
      _this.api.on("websocket-closed", _this.renderWebsocketClosed);
      _this.api.register(_this.register.ext, _this.register.pass, _this.register.domain);
      _this.$registerButton.addClass("disabled");
      return _this.$registerButton.addClass("disabled");
    };
    this.api = new API({
      server: sipServer,
      turnServer: turnServer,
      stunServer: stunServer,
      mediaElements: this.mediaElements,
      onopen: onopen,
      mediaConstraints: {
        audio: true,
        video: !onlyAudio
      }
    });

    return this.api.on("localstream", function() {
      return _this.$mediaLocal.removeClass("hidden");
    });
  };

Any idea why this websocket closed call back is not hitting the second time.

Hi @sumantasen, I think this behaviour is normal.

1. You get a websocket opened, so you are able to register.
2. Your server gets down, you catch an "websocket-closed".
3. You try to open a websocket again, but the server is still down, so you cannot get a websocket-closed cause this new websocket never gets opened.

I have also tries to incorporate onerror(), we still get the same error.
