Abstract
ITU-T recommendation G.107 introduced the Emodel,
a repeatable way to assess if a network is prepared to
carry a VoIP call or not. Various studies show that the Emodel
is complex with many factors to be used in monitoring
purposes. Consequently, simplified versions of the E-model
have been proposed to simplify the calculations and focus on
the most important factors required for monitoring the call
quality. In this paper, we propose simple correction to a
simplified E-model; we show how to calculate the correction
coefficients for 4 common codecs (G.711, G.723.1, G.726 and
G.729A) and then we show that its predictions better match
PESQ scores by implementing it in a monitoring application.
