VOIP Project: Understanding VOIP - Part 4

Image
In order to be able to continue developing further more the VOIP system we need to know which are the components that can be used to build a VOIP system and how they are implemented. In the book titled “Packet Guide to Voice over IP” VOIP is: “…exactly what the name indicates—sending voice (and video) over an IP-based network. This is completely different than the circuit-switched public telephone network…” ( Hartpence, 2013, p. 2). The fact that VOIP “…is completely different than the circuit-switched public tele‐ phone network…” ( Hartpence, 2013, p. 2)makes it possible to do things that are not possible with the standard telephony system, like programming customized applications based on individual needs. VOIP does not only allows to transmit voice over IP but video as well, and this makes communication through VOIP even richer in features. Comparison with traditional telephony VOIP gives the opportunity to use internet connection in order to implement system, while the trad...

C++ Beginner: Lesson 3 - Simple calculator

Image
After we got familiar with Qt Creator environment in the lesson 2 we will build a simple calculator in order to get familiar with some data types which come with Qt Creator framework like QString and other C++ primitive data types. First of all we need to create a new project as shown in the lesson 1 . During the creation, instead of mainwindow class we have used calculator class. After creating the project, in design view of qt creator we create the layout of our application. Initially we get a LineEdit element from the toolbox panel as shown in the figure 1. Figure 1: Add LineEdit on window After we add the line edit on window we fix the size according to our needs, in this case we fill the window horizontally by leaving some margin right and left. After we add the LineEdit element on window we need to add the buttons for the numbers and operations as well as shown in the figure 2. Figure 2: Add PushButton on window After we add the buttons as shown in the figure above we ...

VOIP Project: Design application - Part 5

Image
In this part we will see in details the UML diagram of the application which will be developed during this project and the specifications of this diagram. In the figure 1 bellow is shown a preview of the class diagram of the application developed with Qt Creator using PJSIP library. In the diagram below are omitted other external classes which are not used directly by the application. On top of figure 4, within the grey rectangle, are shown the classes of Qt library which are extended by the created classes by the programmer. The QMainWindow is a class which provides a framework for building a graphical view, this is the reason why this class is extended by Login and MainWindow classes. The other class, QObject is a base class for many classes in Qt. It provides a wide set of features. The QObject class is extended by SipPhoneImpl class as well because of usage of signals, which will be explained more in deep in the upcoming paragraphs. Figure 4: Class diagram preview In the ...
