Patent ID: 7742462

Claim:
A CD-ROM having a program recorded to set up a general-purpose computer as an IP telephone terminal by using at least a CPU, a memory, an input means, a network card, a sound card, and a CD-ROM drive except a hard disk (HD) drive, comprising: a part of said program for making the general-purpose computer get started by initiating the general-purpose computer with the CD-ROM set at the CD-ROM drive to deploy the program recorded on the CD-ROM over the memory by a CD-ROM boot method without the hard disk drive; wherein a unique manufacturing serial number has been originally pre-assigned to the CD-ROM even when the CD-ROM has been duplicated, a part of said program for making the general-purpose computer obtain a user identification data which respectively corresponds to users and which is inputted by a user through the input means; a part of said program for making the general-purpose computer send thus obtained user identification data to a management server via a network, based on a first location data recorded on the CD-ROM to designate a location of the management server; wherein the management server has a database for registering a plurality of the user identification data and the manufacturing serial number corresponding to each respective user identification data, an obtaining device for obtaining from the database the manufacturing serial number corresponding to the user identification data sent from the general-purpose computer, and a sending device for sending an IP telephone terminal setup data including the obtained manufacturing serial number to the general purpose computer via the network; a part of said program for making the general-purpose computer receive the IP telephone terminal setup data sent from the management server via the network; and a part of said program for making the general-purpose computer function as a dedicated purpose terminal for IP telephony by setting up the general-purpose computer as the IP telephone terminal without the HD drive, wherein a second location data is included in the IP telephone terminal setup data, in order for designating a location of an operation server used for telephone switching, and further including: a part of said program for making the general purpose computer send the manufacturing serial number included in the IP telephone terminal setup data to the operation server via the network, based on the second location data in order to register the general-purpose computer as the IP telephone terminal.
