Patent attributes
An IP phone terminal registration method capable of reducing the workload as to telephone terminal setup and excluding working mistakes by achieving automated phone terminal registration is provided. Upon connection of a telephone terminal to IP network, a DHCP device issues a terminal registration request to a main apparatus. The main apparatus performs automated phone number allocation to thereby perform terminal registration processing. The DHCP device sends back to the telephone terminal an item of network information that contains therein IP address of the main apparatus and the phone number thus allocated. The phone terminal sets up the IP address of main apparatus and the phone number as self-terminal information, thereby automating the phone terminal registration.
