First Claim
1. An Internet Protocol (IP) telephone apparatus connected to a Telephone Number Mapping (ENUM) server and a Domain Name System (DNS) server via a network, the ENUM server storing a Naming Authority Pointer (NAPTR) resource record of the IP telephone apparatus, the NAPTR resource record including a domain name corresponding to a Uniform Resource Identifier (URI), the domain name and the URI being associated with the IP telephone apparatus, the DNS server storing an IP address corresponding to the URI, the IP telephone apparatus comprising:
- a memory that stores the NAPTR resource record of the IP telephone apparatus, and that stores a plurality of telephone numbers, wherein each telephone number is associated with a different predetermined call destination to transmit a notice indicating that a user of the IP telephone apparatus is available;
a panel that includes;
a first predetermined key, when actuated by the user of the IP telephone apparatus, that causes the IP telephone apparatus to initiate an automatic notification of each of the different predetermined call destinations that the user is available to answer the IP telephone apparatus;
a second predetermined key, when actuated by the user of the IP telephone apparatus, that causes the IP telephone apparatus to initiate an automatic notification of each of the different predetermined call destinations that the user is not available to answer the IP telephone apparatus, anda controller that;
transmits, to the ENUM server, a request for registering, in the ENUM server, the NAPTR resource record stored in the memory of the IP telephone apparatus when the predetermined key of the panel is selected, whereby the ENUM server stores the NAPTR resource record of the IP telephone apparatus in response to the request,obtains, from the ENUM server, a NAPTR resource record of each predetermined call destination, based on the plurality of telephone numbers stored in the memory of the IP telephone apparatus when the first predetermined key of the panel is selected,obtains, from the DNS server, an IP address of each predetermined call destination, based on the URI included in the NAPTR resource record of each predetermined call destination obtained from the ENUM server, andtransmits, to each predetermined call destination, a notice indicating that the user of the IP telephone apparatus is available, based on the IP address of each predetermined call destination obtained from the DNS server.

Abstract
A CPU of an IP telephone apparatus transmits, to an ENUM server, a message “Request the NAPTR record” corresponding to the destination terminal. The CPU also receives a message “Respond to the NAPTR information” in response to the message “Respond to the NAPTR record”. Further, the CPU automatically transmits, from a network I/F to the ENUM server, the request for the registration of information regarding the apparatus terminal when the switch is initially turned ON after the IP telephone apparatus is installed and connected to the IP network. The request for the registration is previously stored in a memory. The CPU also receives the message “Respond indicating completion of the registration” in response to the request for the registration.
