  Abstract

This paper describes the Extended E-model which can be used to calculate voice quality of VoIP systems using various factors affecting the quality. The proposed model calculates two parameters, end-to-end delay and packet loss ratio, with device, user, and network characteristics. The model then generates R-value through existing E-model. In this paper, we describe the design and implementation of the model, as well as the validation using OPNET modeler. The results show that the differences between voice quality values from the existing and Extended E-model are less than 10%. Since we can calculate voice quality values through various factors using the proposed model, voice quality can be predicted without measuring factors from real network.
