The use of telephone services over the IP network is currently increasing, replacing traditional telephone services. Call it like skype service that not only provides IPbased telephone services but also video communication. The use of this IP technology was also adopted in the LTE network because traditional voice communication services were not supported by LTE. One of the capabilities of LTE is providing IP-based voice communication services and having mobile capabilities. In this study simulation of voice transmission on Long Term Evolution network with the parameters of the type of codec used, bitrate codec mode, random loss model, burst loss model, and mobility of voice over LTE users to see the effect on the received sound quality. The voice sent uses G.711, G.722, G.729, AMR-WB and AMR-NB codecs. Results from sound. The quality of the received sound results is measured using Perceived Evaluation Speech Quality to produce the MOS objectively and Mean Opinion Score Subjective.
