Abstract
Voice over IP (VoIP) also known as IP Telephony (IPT) has been in existence for many years. It has only recently begun to take off as a viable alternative to Traditional Public Switched Telephone Networks (PSTN). Interest and acceptance has been driven by the attractive cost efficiencies, innovation support and improved access to communications services that organizations can achieve by leveraging a single IP network to support both data and voice over their Internet or Intranet.
However, these new technologies pose challenges for regulators, because they do not fit neatly within the regulatory model of the recent past, which in many countries have traditionally treated voice and data services differently.
Nevertheless, there seems to be a growing recognition in national and international bodies that these issues need to be resolved in ways that permit IP technologies to be used for voice communications, this will advance the goal of affordable services, support the deployment of the broadband networks and services that represent the future of communications in the era of digital convergence.
This dissertation explores VoIP implementation fundamentals, focusing on VoIP infrastructure considerations for an organization or a company to deploy VoIP: VoIP bandwidth consideration (network capacity), quality of service (QoS) consideration, voice quality consideration, network devices, Session Initiation Protocol (SIP) and network assessment. The study would challenge the VoIP Service Providers to tackle more complex issues in the Internet protocol in order to deploy a secure, reliable and high performance VoIP network.
