UNJUK KERJA VOICE OVER INTERNET PROTOCOL PADA JARINGAN LOKAL UNIVERSITAS JENDERAL SOEDIRMAN
Abstract: Jenderal Soedirman
University (UNSOED) LAN covers all of its units that spread not only in
Purwokerto area, but also in Purbalingga. Therefore, it may be possible to
implement VoIP system in order to replace the internal campus voice
telecommunication system that still use PSTN and PABX (line extensions). The
Implementation of VoIP technology into UNSOED LAN needs a VoIP server prototype
to be built for quality testing. VoIP quality of service (QoS) is based on
delay, jitter, and packet loss. These parameters will be used as QoS test
parameters in this research. We also add subjective test runs by users to
measure the voice quality of VoIP. According to Ridwan (2011), the optimum
codec that can be applied in UNSOED LAN is iLBC. Our research result shows that
the highest mean for delay, jitter, packet loss respectively are 3
milliseconds, 19,333 milliseconds, 1%, and the voice quality is good . These
indicated that the VoIP QoS and voice quality on UNSOED LAN is in a good
category.
