Testing of the effect of load on voice quality in VoIP networks

Popis výsledku v původním jazyce

One of the main challenges in VoIP networks seems to be quality of speech signal in VoIP transmission channel. The assessment of the call quality for the above mentioned networks requires using new approaches. Nowadays, there are many standardized subjective and objective sophisticated methods of speech quality evaluations. We can find a series of software tools working in accordance with the required recommendations and laws of statistics that are designed to assess the current state of ongoing VoIP communication. We chose Alcatel VoIP Assessment Tool 3.0 and widely known CommView SW. We tested the parameters and their combinations that influence the quality of the transmitted voice most. Presented results are obtained from the measurement done on systems which perform in real networks of the Armed Forces of the Czech Republic (the ACR).
