Introductions:

The JavaScript SDK for WebRTC call.

SDK usage guidelines:

Main components:

• UserSession: For initializing session from client to Call server.

  • Constructor:

    UserSession(user)

    • user options:

      • wssUrl: Socket URL to the Call Server

      • extension: Extenstion name

      • domain: Domain name

      • password: Plain password

      • callOptions: {

          callerIdName: Caller Id Name
                  
          callerIdNumber: Call Id Number

        }

      • userInfo: {

          // Other info here. Ex. email
                   

        }

      • autoReconnect: Default: true

      • autoRecoveryCall: Auto recovery the call when browser tab closed unexpectedly. Default: true

  • Properties:

    • isLoggedIn: Whether user logged in.

  • Methods:

    • connect(): Connect to the Call server with user options
    • close(): Close the connection to the Call server.
    • on(EVENT_NAME, callback): Start listening a UserSessionEvent:
      • EVENT_NAME: UserSessionEvent event
      • callback(err, data): Callback function for handling the event.
    • off(EVENT_NAME[, callback]): Stop listening a UserSessionEvent
    • testSpeed(): Test connection speed to the Call server. The data will be returned into Promise object or sent to UserSessionEvent.ON_SPEED_CHANGE.
      • Return: Promise({ upDur, downDur, upKps, downKps })
      • on(UserSessionEvent.ON_SPEED_CHANGE, (err, { upDur, downDur, upKps, downKps } ))
    • newCall(options):

      • options:

        {

          destinationNumber: (required) Extension or number
          callerIdName: (optional)
          callerIdNumber: (optional)
                        

        }

• UserSessionEvent: Events will be emitted during the Call Session. We can catch those events with callback functions:

  - Ex:

    const session = new UserSession(user);
    session.on(UserSessionEvent.<EVENT_NAME>, (err, data) => {
        console.log(err, data);
    })
