beneficial  for companies that make significant numbers of  long-distance calls.  For an IP telephony call, the customer pays only  for the call to the  internet and its own company intranet. Thus, the calls are billed at  local  tariff instead of long-distance charges. This technology uses IP   networks such as the   or other packet switched networks for routing  the calls and provides a  cost effective alternative to traditional PSTN  (public switched  telephone network) phones. There are three types of  connections in IP  telephony, namely, telephone to telephone, telephone  to  and computer to computer.
IP telephony is a sophisticated technology that allows audio, video, wired as well as wireless communication, through the usage of Internet Protocol (IP) networks. It is also possible to easily extend all the components of IP telephony, as the technology uses a single infrastructure for the transfer of data and voice. After the basic configuration of the Internet telephony is done, control system and switches are activated with in-line power supply. Then the IP telephones are connected to the network and the user can make calls. Sometimes the configuration of voice gateways, authorization of users and numbering plan are done by an administrator remotely via a Here are some of the major benefits of IP telephony.
