Introduction Voice over Internet Protocol (VOIP) is a technology that provides voice communication using existing Internet protocols. Over the years the Internet has evolved into a very inexpensive medium that has been used to send e-mails and documents worldwide. VoIP extends this concept and provides the ability to send voice data between people using the IP framework. Because the Internet is an inexpensive medium, implementing voice services through it effectively effectively reduces the costs normally incurred when making calls over regular telephone lines.
Voice over IP (Voice over IP, or voice transmitted using the Internet protocol) is the term used in IP telephony to manage the set of functions for sending voice information using the IP protocol. Normally, this means that voice information is sent in digital form in individual packets, not the conventional line commitment protocol of the public switched telephone network (PSTN). One of the main advantages of VoIP and VoIP is that it does not cost calls by regular telephone service.
IP Voice, also called Internet telephony voice, is a technology for making phone conversations over the Internet or a private Internet protocol network, not a dedicated voice transmission line. An IP packet containing voice data is transmitted over the network when it is necessary to transmit data while talking (Wikipedia, free encyclopedia, paragraph 1). The term "Internet telephone" is generally applicable to a variety of applications, including voice communication via a network using the Internet protocol. McKnight, Lehr, and Clark (2001) define Internet telephony as "services, applications, and devices that mediate human communication in convergence of the Internet and telecommunications."
Internet telephony is another common communication service enabled by the creation of the Internet. VoIP stands for Internet Voice Protocol, which is the protocol that forms the basis of all Internet communication. This idea began in the early 1990s with voice applications like transceivers for personal computers. In recent years, many VoIP systems are as easy to use and convenient as normal phones. The advantage is that VoIP can be much cheaper than free or traditional phone, especially for long distance telephone, especially long distance internet connection phone such as cable and ADSL, because the Internet transmits voice traffic. VoIP is mature and is a competitive alternative to traditional telephony services. Interoperability between different providers improves, you can make phone calls and answer calls from traditional phones.
