SIP client in Java
Zukal, Martin ; Polívka, Michal (referee) ; Číka, Petr (advisor)
This bachelor’s thesis deals with a design of a client-based application with the utilization of the Session Initiation Protocol (SIP). The first part describes SIP with an emphasis on basic concepts. Then a brief description of the Java programming language which will be used for the implementation follows. The most extensive part is devoted to the description of a design and implementation of the application. Some techniques used during the development of the applicaton are being discussed in this part. The thesis is finished up with test scenarios verifying functionality of the application.

Optimization of Wireless Networks against Attacks
Řezníček, Martin ; Pust, Radim (referee) ; Škorpil, Vladislav (advisor)
The work describes the design of wireless networks and the problems relating to this technology. In the theoretical part it deals with the learning network, the security technology and design wireless network. In the practical part it describes the simulation and measure of the signal strength. The ensuring of the safety by aid WPA as well as Radius authentication, TKIP data encryption, and the possibility of breaking into the network. The following chapters deal with the connection of the users to the network (domain) and with the application of VOIP telephony on the network. The last part describes the extension of the network and the associated problems.

Intercommunication of Asterisk and VCON VoIP PBX
Balon, Jiří ; Říha, Kamil (referee) ; Číka, Petr (advisor)
The main goal of this bachelor thesis was to familiarize with VoIP telephony development and its nowadays utilization. First part of the work includes description of known communication protocols SIP and H.323 architecture and their usage in communication. Next part is dedicated to software PBX Asterisk that runs under Ubuntu distribution of Linux operation system. The process of PBX installation is described there as well as its adjustment for SIP and H.323 for communication within IP net. There is also described software PBX VCON that runs under Windows XP operation system. Beyond the adjustment of the PBXs there is also concrete adjustment of software clients SJPhone and X-Lite that are necessary for communication between individual telephone exchanges. The final chapter is dedicated to the problems of mutual connection (intercommunication) of individual telephone exchanges Asterisk and VCON.
