Abstract: Circuit switched network or packet switched networks are used for both visual and vocal communication. Public switched telephone network (PSTN) is not an affordable option when comparing with existing packet switched network. Voice over internet protocol (VoIP) has become a preferable alternative due to its reduced cost and flexibility compared to voice over LTE (VoLTE) where carriers are still building out their 4G networks. However, despite its reduced cost, it has to face so many challenges which affect its successful deployment. The reason is that the quality of VoIP is mainly affected by jitter, delay, packet loss and various other parameters. This research was carried out to evaluate the quality of voice in VoIP experimentally, under the effect of interference and during conference calls. The simulations were carried out using Riverbed Modeler academic edition 17.5. The results of the analysis and the performance evaluation are presented in this paper. This work can guide researchers and designers to design a network for VoIP services and its deployment based on their requirements.
