VoIP (voice over IP) a set of facilities used to manage the delivery of voice over the Internet. VoIP involves sending voice information in digital form in discrete packets instead of using the traditional circuit-committed protocols of the public switched telephone network (PSTN). Ne big advantage of VoIP and Internet telephony is that it avoids tolls charged by traditional telephone service.
VoIP is derived from the VoIP Forum, an initiative by major equipment manufacturers, such as Cisco, VocalTec, 3Com, and Netspeak to promote the use of ITU-T H.323, which is the standard for sending voice (audio) and video using IP on the public Internet and within an intranet. The Forum also promotes the user of directory service standards so that users can find other users and the use of touch-tone signals for automatic call distribution and voice mail.
In addition to IP, VoIP utilizes real-time protocol (RTP) ensuring that packets get delivered in a timely way. Currently, using public networks, it is difficult to guarantee Quality of Service (QoS). Better service is possible with private networks managed by an enterprise or by an Internet telephony service provider (ITSP).
A technique used, to help ensure faster packet delivery is to use ping to contact all possible network gateway computers that have access to the public network and choose the fastest path before establishing a Transmission Control Protocol (TCP) sockets connection with the other end.
To use VoIP, an enterprise places a "VoIP device" at a gateway. The gateway receives packetized voice transmissions from internal users and then routes them to other segments of its intranet (LAN or WAN) or, using a T-carrier system or E-carrier interface, sends them over the public switched telephone network.
