Abstract

Several types of codecs in VoIP are G.711, iLBC, GSM and Speex. This study aims to compare the quality of calls through different codecs and design a VoIP practicum module for students. The research method was carried out by conducting literature studies, planning network design, device configuration, determining QoS parameters and testing VoIP calls to determine the quality of VoIP calls through different codecs. From the analysis, it is found that G.711 is an audio codec with very good QoS parameters, namely a delay of 5.28 ms; jitter 5.12 ms; 347.04 kbps throughput, 0% packet loss, and 64 kbps bandwidth. while for audio codec with good enough parameters, namely GSM with a delay of 42.02 ms; jitter 19.46 ms; 39.18 kbps throughput, 0% packet loss and 13kbps bandwidth. In addition to data testing, non-technical testing was carried out on 16 respondents with pre-test, post-test and questionnaire testing. From the pre-test, respondents got an average score of 45, while in the post-test it increased to 70.
