Abstract

There has been an increasing demand for converged solutions in telecommunication sector. Up until recently only monolithic solutions were available which were consequently expensive. There are several tools at our disposal today, which permit us to develop converged solutions in-house. Many among them are available for free. In thesis is addressed a problemof convergence of IP telephony and worldwide-web. Our goal is to present a converged solution in form of a web application - WebPhone. Application provides telephone and web services to its users and has been developed using exclusively open source tools and libraries. Furthermore, the solution permits further extensions in form of additional services. A substantial part of the thesis is concentrated on SIP. SIP is a protocol used for handling VoIP sessions. Theoretical background of SIP is described at the beginning of the thesis using simple examples and its practical use inside the application in the following chapters. WebPhone application was written in Java using tools Mobicents, Seam and JBoss AS. During evaluation we took note of usability, modularity and portability. Usability was verified by integrating the application into telephone network and modularity by incorporating a new functionality into the application. Portability was shown to be varying depending on its type. In general we succeeded to demonstrate the possibility of developing a converged application using the right protocols, tools and libraries.
