IP Telefonia

Voice over ip VOIP development of the TCP/IP protocol stack came to revive existing networks of fixed telephony world allowing the flow of data with dial-up connections. These connections had the limitation that if navegabas by internet could not speak by phone and vice versa. Years later with the arrival of the adsl technology achieved use the telephone network to transfer data at high speeds held the pair of wires so that data does not interfere with the voice thus giving birth to a new generation of the internet in which stacks that would add new services to the network of networks that would transform our lives would be developed. VOIP(Voice Over Ip) or voice over is a set of protocols used to transfer voice by using the Protocol ip and all the infrastructure that is used to transfer data. The development of VOIP protocols began a new technology known as IP Telefonia.

IP telephony: IP telephony is technology employing protocols VOIP over broadband that transfers data, voice and video through old fixed telephone networks. This technology includes a wide range of hardware components such as IP phones, pci cards that convert the analog signal of normal phones in packages that are used by the IP protocol for your transfer. How it works traditional telephony is said to be a traditional telephone network a network switching circuits, which means that if you set a named telephone with your neighbor who is just a couple of metres you’ll be occupying two threads in its entirety copper ranging from your phone to the telephone exchange and the PBX to your neighbor’s House. So far everything seems very normal, but is that a switched packet network offers you more. A network switched packet network commuted by packages using VOIP can be very efficient since the analog signals of the human voice are digitized and formatted into small packets of data ip or datagrams that van equipped with information in his cabeceera needed to reach the destination and reassembled in the order in which they were sent.
