Abstract: The present invention relates to a device, as well as a method, of a multi-service IP-phone. The device and method comprise an IP-phone, to be used for making intercom and inbound/outbound phone calls through a LAN or the Internet, and a network control unit, to be used to control the data transmitting through the network. By connecting the IP-phone with network devices and computer devices, one can not only use the IP-phone to receive and make phone calls, but also use the computer devices to access the LAN or the internet via the IP-phone, which at the same time, with its built-in network control unit, provides such functions as LAN/internet security, data security, packet filtering, bandwidth management, traffic shaping (load balance), and virtual private network (VPN).
