Voice over Internet Protocol (VoIP) is a technology that makes it possible for users to make telephone calls over the internet or intranet networks. The technology does not use the traditional Public Switched Telephone Network (PSTN); instead calls are made over an internet protocol data network.
38 Practical Fundamentals of Voice over Internet Protocol (VOIP) for Engineers and Technicians. Real Time Transport Protocol (RTP) along with its companion protocol RTP Control Protocol (RTCP) allows receivers to compensate for the jitter and desequencing caused by IP networks. RTP and RTCP operate above UDP.
Some of the current protocols include SIP, IAX, H.323,MEGACO, and MGCP. Let’s look at some details of the first three, as they may be the ones you are most likely to encounter. SIP, or Session Initiation Protocol, is the most commonly used VoIP protocol and was developed by the Internet Engineering Task Force (IETF).
Since the late 90's IP telephony, commonly referred to as Voice over IP (VoIP), has been presented as a revolution on communications enabling the possibility to converge historically separated voice and data networks, reducing costs, and integrating voice, data and video on applications.
Introduction With the rapid adoption of Voice over IP (VoIP), many telephony and data network techni- cians, engineers, and designers are now working to become proficient in VoIP.
VoIP Protocol Fundamentals. 2.1 Introduction. Successful VoIP communication is ensured by implementing robust protocols that not only manage to preserve the QoS of ongoing transmissions but also ensure maximum utilization of the system resources.
Voice over Internet Protocol (VoIP) is a form of communication that allows you to make phone calls over a broadband internet connection instead of typical analog telephone lines. Basic VoIP access usually allows you to call others who are also receiving calls over the internet.
