IP telephony is convenient way of communication and brings number of benefits. One of them is the fact that many services can be implemented in a original way and it opens new field of research and is a challenge for designers of communication solutions especially based on open-source platform. This article describes proposal and advanced implementation of IP telephony which have been arisen in...

IP telephony, also called voice over Internet protocol (VoIP), is rapidly becoming a familiar term and technology that is implementing in the enterprise, education, government organizations and industry. Mobile IP telephony is the new generation of communications networks that makes possible the convergence of voice and data over wireless local area networks (WLANs). This technology combines da...

This article seeks to develop a richer understanding of the suitability of IP telephony in the Public Switched Telephony Network (PSTN) with an actual local exchange carrier (LEC)’s case and network simulation. We also performed a simple real options analysis to evaluate a telecommunications network. The underlying network and associated data were derived from our studies of an actual LEC. The ...

Voice over IP (VoIP) is a family of technologies, methodologies, communication protocols, and transmission techniques for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and often used synonymously with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband tele...

The IP telephony market has been subject to publicity due to the recent increase of users worldwide. Although not a new technology, given that IP telephony was developed in the mid-nineties, it lately became popular as a lower-priced alternative to fixed telephony through the availability of high bandwidth networks. While prior studies focused on technical aspects such as quality of service and...
