Voice over LTE (VoLTE) Speech Quality Measurements

This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively. The CMWrun example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis under IP impairment conditions.
