First Claim
1. An IP telephone system comprising:
- an IP telephone apparatus that is connected to an IP network and functions as a base station for a multi-handset telephone system;
a Web server that stores ring tone information corresponding to a telephone number assigned to said IP telephone apparatus, and transmits, to said IP telephone apparatus, the ring tone information in response to a request from said IP telephone apparatus; and
an ENUM server that stores a NAPTR resource record in which a URI specifies link data related to the ring tone information, the ring tone information being stored in said Web server, and transmits, to said IP telephone apparatus, the NAPTR resource record in response to a query from said IP telephone apparatus, said IP telephone apparatus, when a call is received, that transmits, to said ENUM server, a query for a NAPTR resource record according to an intended recipient telephone number, transmits, to said Web server, a request for the ring tone information corresponding to the intended recipient telephone number, according to the obtained NAPTR resource record, and sounds a ring tone through the apparatus itself and all handsets that are connected to the apparatus according to the obtained ring tone information.

Abstract
An IP telephone system includes a source IP telephone apparatus, a destination telephone apparatus, a Web server and an ENUM server. The IP telephone apparatuses function as base stations for multi-handset telephone systems and are connected to an IP network. The Web server stores ring tone information corresponding to a telephone number assigned to the source or destination IP telephone apparatus. The ENUM server stores a NAPTR resource record in which a URI specifies link data related to the ring tone information stored in the Web server. In the IP telephone system, the IP telephone apparatus that has received a call transmits, to the ENUM server, a query for a NAPTR record corresponding to an intended recipient'"'"'s telephone number. The IP telephone apparatus then transmits, to the Web server, a request for the ring tone information corresponding to the intended recipient'"'"'s telephone number according to the obtained NAPTR resource record, and sounds a ring tone through the apparatus itself and the handsets that are connected to the apparatus according to the obtained ring tone information
