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.
