Performance Evaluation of VoIP Services using Different CODECs over a UMTS Network

In this paper, we evaluate the performance of Voice over Internet Protocol (VOIP) services that use different compression and decompression (CODEC) schemes, over a hybrid network that includes a Universal Mobile Telecommunications System (UMTS) network segment. We focus on the VoIP transmission end-...

Summary:In this paper, we evaluate the performance of Voice over Internet Protocol (VOIP) services that use different compression and decompression (CODEC) schemes, over a hybrid network that includes a Universal Mobile Telecommunications System (UMTS) network segment. We focus on the VoIP transmission end-to-end delay. We found that different CODECs provide very different results depending on the hybrid network. The research found that for VoIP services to operate over a hybrid network including a UMTS network segment, with an end-to-end delay comparable to that of circuit switched voice service, there is a requirement for careful comparison and design on choosing the CODEC scheme.
