Abstract: Voice over Internet Protocol (VoIP) is one of the online streaming methods used in the organization’s voice operation or conference call to provide voice communication. Researchers have developed several methods in recent years to improve voice quality; however, it still faces some problems of high jitter, delay, and low performance. This paper introduces a VoIP to enable Long Term Evolution (LTE-A) voice calls. To improve voice quality on the LTE-A network, the Enhanced Voice Service (EVS)-Transmission Control Protocol (TCP) Reno VoIP (EVS-TCP Reno-VoIP) method has been introduced. The EVS codec is used to improve voice service, and the LTE-A network uses TCP Reno to prevent voice congestion. The voice based skype testbed experiments are implemented for the LTE-A network. Using Jperf software, network traffic is calculated. VoIP over LTE-A’s Quality of Service (QoS) is analyzed in Network Simulator 2 (NS2). Multiple scenarios were simulated to calculate and analyze performance in terms of end-to-end delay, performance, jitter, and loss of packets. The results of the simulation showed that the EVS-TCP Reno-VoIP method has increased network performance by 2-3.5% compared to existing methods such as EVS codec, G-11, G-723 and SDSS.
