VoIP phone
Internet Protocol (IP) telephony or voice over IP (VoIP) generally refers to transmission of voice calls or voice information over packet-switched data networks that use IP as a datagram protocol. Internet Protocol is a part of the TCP/IP family of protocols described in software that tracks the Internet address of nodes, routes outgoing messages, and recognizes incoming messages. Such a data network may be the Internet or a corporate intranet, or any TCP/IP network. VOIP is viewed as an attractive option for voice transport in that it allows live voice conversations to be integrated with existing IP data and image applications. Voice over Internet Protocol (VoIP) can be defined as the transport of telephony calls over an IP network. In contrast to traditional telephony, where an end-to-end circuit is set up between two endpoints, IP telephony uses the intemet protocol to transmit voice packets over an IP network. A VoIP application segments the voice signals traffic into frames and stores them in voice packets. The voice packets are transported via the network using any conventional multimedia (i.e., voice, video, fax, and data) protocol. Voice over IP enables the management of voice and data over a single network and eliminates the need for expensive, dedicated circuits between facilities. In a VoIP network, a VoIP gateway device is provided between a switched telephone network and an IP network to perform protocol conversion. The VoIP gateway device converts an IP packet stream received from the IP network to a data stream to be transmitted to the switched telephone network, and vice versa.

VoIP is no longer a technical novelty, but a real business for a growing number of for-profit organizations that sell and service VoIP connectivity.
