IP telephone exchange is the latest generation telephone system that replaces the traditional digital telephone exchange. The main difference between IP telephone exchange and digital telephone exchange: to provide voice communications via IP telephone exchange, is used exclusively and only data transmission network. Thus no longer need to maintain 2 independent data communications networks: internal (LAN) and external (WAN).
IP-PBX main advantages are: extensive functionality, convenient and fast equipment service, flexible enlargement options and, of course, relatively low costs of its implementation and maintenance.
PC and telephone connection to Local Area Network (LAN)
One of the main advantages of IP telephony solution: it is not necessary to have two internal networks - voice network and the company's internal PC network. The implementation of IP telephony solution also does not require additional investments to ensure every job place with 2 network sockets. Each IP telephone is equipped with a built-in switch function, so the user needs only one network socket to connect telephone and PC.
