Connection to an existing session

Sometimes it is necessary to connect to already existing session and receive an incoming call. It is usually actual on mobile devices where websocket session is closed automatically when browser goes to background. In this case, only push notifications are available. To keep the sesssion active after disconnection, the keepAlive option should be set while creating the session

    var connectionOptions = {
        urlServer: url,
        keepAlive: true,
        sipOptions: sipOptions
    };
    ...
    Flashphoner.createSession(connectionOptions).on(SESSION_STATUS.ESTABLISHED, function(session, connection){
        ...
    });

In this case, session stays active until the following interval in milliseconds is expired (3600 seconds, or 1 hour by default)

client_timeout=3600000

This interval is periodically checked. The checking priod is set in milliseconds by the following parameter (300 seconds, or 5 minutes by default)

client_timeout_check_interval=300000

A session token should be stored while creating the session

    Flashphoner.createSession(connectionOptions).on(SESSION_STATUS.ESTABLISHED, function(session, connection){
        authToken = connection.authToken;
        ...
    });

Then application may connect to the session again using this token (for example, if incoming call push notification is received):

    var connectionOptions = {
        urlServer: url,
        keepAlive: true
    };

    if (authToken) {
        connectionOptions.authToken = authToken;
    } else {
        connectionOptions.sipOptions = sipOptions;
    }

    Flashphoner.createSession(connectionOptions).on(SESSION_STATUS.ESTABLISHED, function(session, connection){
        ...
    });
