	Voice over IP - Wikipedia, the free encyclopedia
		Voice over Internet Protocol (also called VoIP, IP Telephony, Internet telephony, and Digital Phone) is the routing of voice conversations over the Internet or any other IP-based network.
		Protocols used to carry voice signals over the IP network are commonly referred to as Voice over IP or VoIP protocols.
		Voice over IP traffic may be deployed on any IP network, including ones lacking a connection to the rest of the Internet, for instance on a private building-wide LAN.

		Instead, packet switching is used, where IP packets with voice data are sent over the network only when data needs to be sent, i.e., when a caller is talking.
		Users are typically completely unaware that their telephone call is being routed over IP infrastructure for most of its distance instead of the circuit switched PSTN.
		Notable exception is IAX which carries both signaling and voice data over a single UDP stream, which results in fewer problems while traversing firewall and NAT devices.

	Voice Over Internet Protocol (VoIP)
		Although Voice over Internet Protocol (VOIP) technologies have yet to gain the widespread acceptance originally predicted, the value proposition offered by many VOIP service and technology providers is leading industry analysts continue to expect a boom in VOIP technology and strong financial stability amongst VOIP providers in the near future.
		VOIP traffic is projected to account for approximately 75 percent of the world’s voice traffic by 2007, according to Frost and Sullivan.
		Voice over IP has now been proven feasible and the race is on to adopt standards, design terminals and gateways, and to begin the roll-out of services on a global scale.

	Voice-Over-Internet Protocol
		Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line.
		VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number.
		With many VoIP plans you can talk for as long as you want with any person in the world (the requirement is that the other person has an Internet connection).

	VoIP - a Whatis.com definition - see also: Voice over IP, Voice over Internet Protocol (Site not responding. Last check: 2007-11-06)
		VoIP (voice over IP - that is, voice delivered using the Internet Protocol) is a term used in IP telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP).
		A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service.
		VoIP, now used somewhat generally, derives from the VoIP Forum, an effort by major equipment providers, including Cisco, VocalTec, 3Com, and Netspeak to promote the use of ITU-T H.323, the standard for sending voice (audio) and video using IP on the public Internet and within an intranet.

		Voice over Internet Protocol, or VoIP, is helping to pave the way to cheaper telephone calls and changing the entire telecommunications landscape.
		VoIP is a set of Internet standards that allows a user's voice to be converted into small packs of digital data that can then be sent over computer networks.
		Most VoIP and Internet telephony plans require a fast, dedicated connection to the Internet, such as those found in corporate computer systems or home broadband — cable modems, cable internet, satellite internet, T-1, DSL service or other broadband services.

		While VoIP is viewed as a cheaper and more efficient alternative to traditional telephone use, there are concerns about the long term cost of the software, hardware and infrastructure used in the technology.
		This can be a major issue for those who need to use their telephone after the power goes out to contact their electrical company to report a power outage or to call an ambulance in the case of an emergency.
		Most VoIP systems cannot properly handle outgoing calls from fax machines, TiVO boxes, satellite television receivers, alarm systems, conventional modems or fax modems, and other devices that depend on access to a voice-grade telephone line for some or all of their functionality.

	IEC: Voice over Internet Protocol
		Internet telephony refers to communications services—voice, facsimile, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN).
		The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.
		This tutorial discusses the ongoing but rapid evolution of Internet telephony, the market forces fueling that evolution and the benefits that users can realize, as well as the underlying technologies.

	The Internet telephone: Voice over Internet Protocol (VoIP)
		VoIP has the potential to enable cheaper long distance and international telephone voice calls than the normal public switched telephone network (PSTN), but not without some upfront costs and technicalities.
		Each VoIP telephone has an Internet Protocol address that fully identifies the handset no matter where in the world it is located, thus offering the ability of a single ID number.
		While VoIP’s access to 000 is comparable with that of PSTN services, the nature of the VoIP service means that the location of the caller may not always be certain.

	LLRX.com - Voice Over Internet Protocol (VoIP) Opportunity Arises
		The Internet was not originally designed to carry data and voice communications, and many of the components within a network needed to mature before IP telephony could advance.
		Voice traffic is subject to line drops, delays, echoes, and a choppiness referred to as “jitter.” Broadband networks go a long ways toward resolving those problems.
		The bad news is that the peer-to-peer protocol is not recognized by the International Telecommunications Union, which has established two protocols (H.323 and SIP) as the standards for the industry.

		It is the central contention of this paper that Voice over Internet Protocol (VoIP) represents such a strategic inflection point for all incumbent telecommunications operators like BT and that consequently the company and its staff face major challenges but also some significant opportunities.
		In the past, packet switching was not used for voice because the breaking up and reassembly of the packets would cause an unacceptable deterioration in quality, notably because of the variable delay in the packets.
		VoIP is a truly disruptive technology and one of the early challenges it will pose is to the existing regulatory frameworks and rules.
