Voice over Internet Protocol (VoIP) allows users to make voice calls using an Internet connection instead of a regular phone line. VoIP converts voice signals from phones into digital data packets that can be transmitted over the Internet or a private IP network. Major VoIP providers have adopted various business models and technical solutions for transmitting calls, including the use of codecs to compress audio and video, and features like voicemail, caller ID, and call forwarding.
![• Early providers of voice over IP services offered business models and technical solutions that
mirrored the architecture of the legacy telephone network. Second-generation providers, such as
Skype, have built closed networks for private user bases, offering the benefit of free calls and
convenience while potentially charging for access to other communication networks, such as the
PSTN. This has limited the freedom of users to mix-and-match third-party hardware and software.
Third-generation providers, such as Google Talk, have adopted[1] the concept of federated VoIP—
which is a departure from the architecture of the legacy networks. These solutions typically allow
dynamic interconnection between users on any two domains on the Internet when a user wishes to
place a call.
• VoIP systems employ session control and signaling protocols to control the signaling, set-up, and
tear-down of calls. They transport audio streams over IP networks using special media delivery
protocols that encode voice, audio, video with audio codecs, and video codecs as Digital audio by
streaming media. Various codecs exist that optimize the media stream based on application
requirements and network bandwidth; some implementations rely on narrowband and compressed
speech, while others support high fidelity stereo codecs. Some popular codecs include μ-law and a-
law versions of G.711, G.722, which is a high-fidelity codec marketed as HD Voice by Polycom, a
popular open source voice codec known as iLBC, a codec that only uses 8 kbit/s each way called
G.729, and many others.
• VoIP is available on many smartphones, personal computers, and on Internet access devices. Calls
and SMS text messages may be sent over 3G or Wi-Fi](https://image.slidesharecdn.com/voiceoverinternetprotocol-140522165003-phpapp02/85/Voice-over-internet-protocol-3-320.jpg)

- 2. • Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, IP communications, and broadband phone service. • The term Internet telephony specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN). The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network, however, the digital information is packetized, and transmission occurs as Internet Protocol (IP) packets over a packet-switched network. Such transmission entails careful considerations about resource management different from time- division multiplexing (TDM) networks.
