ITU-T P.863 is the next generation voice quality testing technique suitable for ifxed, mobile and IP-based networks. A known reference signal is compared with the degraded signal to obtain P.863 mean opinion score (MOS). The voice quality of handset with perceptual objective listening quality assessment (POLQA) algorithm was objectively assessed and the different factors affecting voice quality of handset were analyzed.
