Arquitetura de Monitoração de Qualidade de Chamadas Telefônicas IP

Leandro LustosaPaulo AguiarFabio DavidDouglas Quinellato

A voice quality monitoring architecture based on the development of the VQuality library is described. VQuality implements the E-model and its extensions for objective voice quality measurement. The library also supports the generation of a voice quality CDR with extensions for the transfer of quality parameters collected over different instants of time along the call, besides interacting with RADIUS for data collection. The framework is exemplified in the context of the fone@RNP VoIP service and the use of a modified Openphone client incorporating the new functionality is shown.
