“…the most common codecs used for VoIP applications are G.711, G722, G723, G726, G728, G729A, etc. each of which varies in the sound quality, the bandwidth required, the computational requirements, encoding algorithm and coding delay [3,9,10]:…”

“…However, while IPv6 gives greater flexibility and assurance for security if deployed and configured correctly [20], the difference with IPv4 is not significant because both protocols are network layer based and are vulnerable to similar types of attack [19]. Studies show that IPv6 based VoIP deployment can deliver no less quality than IPv4 based VoIP deployment [21].…”

The advance of technology often requires the emergence of complementary technologies, of which the transition from IPv4 to IPv6 presents a significant example. The move of protocol has focussed attention on the level of performance for associated technologies. Among the many Internet applications, in contemporary digital communications, VoIP stands apart in importance. This paper presents a performance analysis of VoIP using IPv4 and IPv6. Using OPNET to simulate the protocols and to investigate areas of performance weakness.

“…Voice over Internet Protocol (VoIP) are likely to increase day by day, leading to rapid network improvements. There is a demand to reduce the differences between the qualities of voice and increasing the available bandwidth to provide the best VoIP service [1].VoIP has almost replaced the traditional Public Switched Telephone Network (PSTN) due to its cost effectiveness and the features being offered [2]. The wired Internet Protocol (IP) networks provide better VoIP services than wireless IP network since wireless networks have their own characteristics and impairments [3].…”

The paper discussed the implementation of the use of Voice over Internet Protocol services, which is resulting in the enormous growth of broadband network. The main objective of this paper is to evaluate the QoS of VOIP for different broad band networks. Wired, Wireless Local Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX) and Universal Mobile Telecommunication System (UMTS) networks were implemented in OPNET Modeler The quality is compared using different QoS parameters such as end-to-end delay, Mean Opion Score (MOS), throughput and jitter. The VoIP codes used in the measurements of QoS is G.729A with sampling rate of 8 kbps .The results analyzed and the performance evaluated will give network operators an opportunity to select the codec for better services of VoIP for customer satisfaction.
