Abstract :
This article presents a voice quality measurement tool based on the ITU-T E-model. Firstly, the ITU-T and ETSI specifications of E-model are briefly reviewed and some errors found in these documents are pointed. After, a measurement tool based on the corrections is described. VoIP calls through the Brazilian National Education and research network (RNP) backbone were used to verify the tool operation.
