Abstract

The paper describes the IP network as a basis for the voice services transfer and parameters which influence the quality services level in the voice transfer over the IP network. Among all parameters, the accent is given on delay components, special on variable components. Hereafter is described the application which we have developed for the purpose of the VoIP/PSTN network planning and analyzing. At the end, testing measurements with the developed application are made whereat the influence of the used codec and the link capacity on the subjective score of voice quality (MOS) and on the total delay of voice packet is analyzed. For the purpose of the developed application verification, a comparison analysis of the testing measurements and measurements on the real
network is carried out.
