Internet Protocol Telephony. IP Telephony or Voice over IP (VoIP) is the technology that enables voice (telephone) calls to be carried over IP network (over LAN or Internet) instead of telephone network (PSTN). Also see VoIP.
An umbrella term to describe the use of Internet Protocol (IP) and packet-switching to provide voice, fax, and other services that once were solely accessible through circuit-switched networks such as a PBX or the phone company. ISDN (Integrated Services Digital Network) - An international standard for digital transmissions over standard copper wiring. ISDN is delivered in 2 forms, Basic Rate Interface (BRI) and Primary Rate Interface (PRI). BRI provides 2 digital lines (called B-channels) of 64 Kbps each, or 128 Kbps total, for a home or small business. PRI consists of 23 B-channel lines. Both BRI and PRI include a smaller D-channel (12 Kbps for BRI, 64 Kbps for PRI) that carries control and signaling information, but does not increase download speeds. ISDN is growing less common and has generally been supplanted by Digital Subscriber Line (DSL) service.
Method used to send voice traffic across a data network. Also known as VoIP or Voice over IP. Voice signals are broken down into packets and reassembled at the receiving end. This eliminates the need for separate voice and data networks by converging all traffic on one network.
A term used largely interchangeably with Voice over IP and VoIP to describe the transmission of voice -- in this case referring more specifically to voice in the form of live calls, rather than messages -- over data networks.
The transmission of voice and fax telephone calls over data networks using the Internet Protocol.
The two-way transmission of audio over a packet-switched IP network (TCP/IP network). When used in a private intranet or WAN, it is generally known as "voice over IP," or "VoIP." When the transport is the public Internet or the Internet backbone from a major carrier, it is generally called "IP telephony" or "Internet telephony." However, the terms IP telephony, Internet telephony and VoIP are used interchangeably.
Evolving, packet-based systems that can more efficiently move voice and data traffic simultaneously via the Internet. IP telephony technology represents a lower cost alternative to circuit-switches for providing (mostly residential) local service.
Telecommunications services that use the Internet protocol.
Sending voice or fax telephone calls over an IP network, such as the Internet. By treating voice as data, IP telephony can offer integrated communications services, such as unified messaging. Back
Technology that supports voice, data, and video transmission via IP-based LANs, WANs, and the Internet. Voice Over IP is one technology protocol in the broader concept of IP Telephony. The promise and advantage of IP Telephony is that applications will be less media and location dependent as with Public Switched Telephone Network (PSTN) telephony.
IP telephony combines different types of communications-such as data, voice, and video-over a single packet cell-based infrastructure. IP telephony extends the value of the network with these nontraditional applications. By combining different types of traffic on a single network connection, small and medium-sized businesses and small branch offices can dramatically reduce the costs of their voice and data networks.
Telephony services provided over the Internet
The use of IP signalling methods to send voice traffic across a date network. Voice signals ore broken down into pockets and reassembled at the receiving end. This eliminates the need for separate voice and data networks by converging all traffic on one network.
See Internet Telephony.
A form of voice communications in which voice is converted into digital data packets and sent over the Internet using the Internet protocol. See the definition of VOIP for more detail.
Technology that supports voice, data and video transmission via IP-based LANs, WANs, and the Internet. This includes VoIP (Voice over IP). close
A general term referring to technologies that use IP packet-switched connections to exchange voice, data, video, and other forms of information traditionally carried over public telephone networks. (See IP, VoIP). close
(Internet Protocol Telephony): See VoIP (Voice Over Internet Protocol).
Internet Protocol telephony. Hardware and software that enable people to use the Internet to make telephone calls.
The transmission of voice and fax phone calls over a packet-based IP data network; synonymous with VoIP.
A general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge.
The field of communications involved with developing voice transmissions that can take place over an Internet connection. As such, traditional long distance charges can be avoided entirely. While long distance companies have lobbied against IP telephony, the FCC has stated that it has no intentions of regulating the new technology. Currently, only about 1% of (U.S.) long distance calls utilizes the still developing IP telephony.
(Also called Voice over IP) Technology that allows voice phone calls to be made over the Internet or other Packet networks using a PC via Gateways and standard telephones. VoIP primarily builds on and complements existing standards, such as H.323 and SIP.
A category of hardware and software that enables people to use the Internet to transmit telephone calls, faxes, and other form of info over the internet.
Transmitting and receiving telephone messages via the Internet. Messages are broken into packets and exchanged using the Internet protocols.
Using the internet to make telephone and fax calls. Calls travel as packets of data on shared lines, avoiding the costs of the public switched telephone network. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. This depends on Quality of Service (QoS).
The transmission of voice and fax phone calls over data networks that uses the Internet Protocol (IP). IP telephony is the result of the transformation of the circuit-switched telephone network to a packet-based network that deploys voice-compression algorithms and flexible and sophisticated transmission techniques, and delivers richer services using only a fraction of traditional digital telephony's usual bandwidth. Compare with VoIP.
The transmission of voice over an Internet Protocol (IP) network. Also called Voice over IP (VoIP), IP telephony allows users to make phone calls over the Internet, intranets, or private LANs and WANs that use the TCP/IP protocol.
Any of a number of techniques allowing voice communications using Internet technologies and protocols.
This is also known as Internet Telephony or alternatively, Voice over IP (VoIP). It is the use of Internet Protocol (IP, see TCP/IP) in order to carry and also route a two-way voice communication. IP Telephony supports telephone to telephone links by using suitable adapters but also by using voice communications from a telephone to IP terminal (for example a PC with sound card). It can also be used from IP terminal to IP terminal. This technique promises to drastically reduced the costs to carriers and subsequently prices to end users – however, it still suffers from problems with quality.
All telephone type services that work over TCP/IP, including VoIP, text messaging and IP-based faxing.
Using TCP/IP to move voice calls over the Internet or related network
A set of technologies that enables voice, data and video collaboration over existing IP-based LANS, WANs, and the Internet. IP technology uses open IETF and ITU standards to move multimedia traffic over any network that uses IP.
Also known as Voice over IP or Internet Telephony and it represents the technology, which uses IP-based data networks to transmit telephone calls.
IP Telephony allows users to have telephone conversations over the internet.
The use of the Internet or a private IP network for telephony.
