Measuring Quality of Telephone Calls with the Asterisk PBX
 Bílek, Petr ; Šilhavý, Pavel (referee) ; Daněček, Vít (advisor)
This thesis contains description of the present methods and algoritms for measuring the quality of telephone call on the PBX Asterisk. Further develop the concept of a system for measuring and implementing the call embbeded system VOIPAC PXA270M. Based on theoretical analysis is carried out discussions between C, Java and PHP,which results in the selection of appropriate programming language suitable for implementation in embedded system. The concept is realized by creating an application written in a particular programming language. Part of this work is verification created application using experimental measurments of telecommunications system. The results of experimental measurements are discussed in the final evaluation.

 Konečný, Jakub
This diploma thesis focuses on the issue of evaluation VoIP services (from the perspective of QoE) and their quality in university network. It includes theoretical basics of VoIP testing, principals of QoS, and also overview of QoE/MOS measurement methods. Next part describes the test bed and methodology used for measurements and evaluating of results. Site survey results and VoIP quality measurement are evaluated at the end, followed by recommendations that can lead to better VoIP quality in MENDELU wireless network.
