Ip phone system and ip phone terminal registration method

Abstract

A registration method of a voice terminal in a call connecting apparatus, wherein; when a registration request of said voice terminal including a first distinguishing information is received, said call connecting apparatus refers to a storage unit which stores distinguishing information and telephone number of said voice terminal; said call connecting apparatus judges whether there is a distinguishing information that is consist with said first distinguishing information; and when there is no consisted distinguishing information, said call connecting apparatus registers said first distinguishing information in said storage unit with correspondence to a telephone number which is not taken correspondence to any said distinguishing information.

1 . A registration method of a voice terminal in a call connecting apparatus, wherein;
 when a registration request of said voice terminal including a first distinguishing information is received,   said call connecting apparatus refers to a storage unit which stores distinguishing information and telephone number of said voice terminal;   said call connecting apparatus judges whether there is a distinguishing information that is consist with said first distinguishing information; and   when there is no consisted distinguishing information, said call connecting apparatus registers said first distinguishing information in said storage unit with correspondence to a telephone number which is not taken correspondence to any said distinguishing information.   
   
   
       2 . The registration method according to  claim 1 , when there is consisted distinguishing information, said call connecting apparatus registers a telephone number which corresponds to the consisted distinguishing information and network address of said voice terminal in said storage unit. 
   
   
       3 . The registration method according to  claim 2 , wherein said distinguishing information is a MAC address. 
   
   
       4 . The registration method according to  claim 2 , wherein said network address is an IP address. 
   
   
       5 . The registration method according to  claim 1 , wherein said connection request is a UDP packet. 
   
   
       6 . A registration method of a voice terminal in a call connecting apparatus, wherein;
 when said voice terminal is connected to a network, said voice terminal sends a setting information request for requesting setting information necessary for network connection;   when said voice terminal receives said setting information, said voice terminal sends a registration request to said call connecting apparatus;   when said call connecting apparatus receives said registration request, said call connecting apparatus registers network address of said voice terminal included in said received registration request taking correspondence with a previously stored telephone number; and   a destination address of said registration request is the network address of said call connecting apparatus read from a predetermined memory.   
   
   
       7 . The registration method according to  claim 6 , wherein said network address included in said registration request is a network address obtained from reception of said setting information. 
   
   
       8 . The registration method according to  claim 7 , wherein said registration request includes a distinguishing information of said voice terminal and said call connection apparatus registers a telephone number taking correspondence to said network address and said distinguishing information. 
   
   
       9 . The registration method according to  claim 8 , wherein said distinguishing information is a MAC address. 
   
   
       10 . The registration method according to  claim 8 , wherein said network address is an IP address. 
   
   
       11 . The registration method according to  claim 1 , wherein said connection request is a UDP packet.
