An Internet phone dials a server through Internet and the sever analyzes an incoming call of the Internet phone for identifying a network system for the Internet phone. The server distributes corresponding application program to personal computer at user site through LAN. The user site receives phone call through personal computer. Alternatively, the processed Internet phone signal is sent to the server and the signal is sent to the PBX after analog to digital conversion of the gateway box. The PBX sends the address number from the calling party to the conventional phone of the called party to achieve communication between Internet phone and conventional phone. When user dials Internet phone, he selects Internet phone program through computer and clicks Internet phone number or account, or he directly dials through a conventional phone, whereby the conventional phone at user site can communicate with Internet phone.
