The paper deals with a speech quality monitoring system using probes placed on the individual network nodes operating VoIP services. Information on speech quality is measured periodically and the results are then stored on the central server which provides visualization in a form of graph respecting a topology of the probes. Article provides overall description of the technology and algorithms used in the speech quality monitoring system and results achieved in this applied research are verified in real operation. Contribution of the work lies in a proposal of the new multi-agent system enabling speech quality monitoring and in own implementation and its verification in Czech academic network.
