IP telephone auto configuration system and method
View Patent ↗To provide An IP telephone auto configuration system capable of conducting setting and change work of IP telephones connected to a LAN efficiently and accurately. The IP telephone auto configuration system includes IP phones, a DHCP server for assigning IP addresses to the IP phones, an FTP server for storing setting data of the IP phones, and a network for connecting the IP phones, the DHCP server and the FTP server. Each of the IP phones acquires an address of the FTP server and a file name of setting data from the DHCP server after being started, acquires setting data from the FTP server and automatically conducts detailed setting in the IP phone.
1. An IP phone auto configuration system comprising:
IP phones;
a DHCP server for assigning IP addresses to the IP phones;
an FTP server for storing at least one setting data file containing auto configuration setting information for the IP phones; and
a network for connecting the IP phones, the DHCP server and the FTP server,
wherein each of the IP phones:
a acquires an address of the FTP server and a first file name of a setting data file corresponding to the IP phone from the DHCP server after being started,
determines whether there is a difference between the first file name acquired from the DHCP server and a second file name having been retained in the IP phone, and
acquires the setting data file from the FTP server when there is a difference between the first file name and the second file name, and conducting detailed setting in the IP phone automatically based on the setting data file,
wherein:
a range of IP addresses used by the DHCP server is divided into a range using a VLAN and a range that does not use the VLAN, and the setting data file stored in the FTP server contains information indicating whether or not to set a VLAN mode;
after being started, each of the IP phones acquires IP addresses in the range that does not use the VLAN from the DHCP server as its own IP address and an address of the FTP server; and
if the setting data file acquired from the FTP server contains information indicating to set the VLAN mode, the IP phone acquires IP addresses in the range that does not use the VLAN as its own IP address and an address of the FTP server again.
2. The IP phone auto configuration system according to claim 1 , wherein the setting data file stored in the FTP server includes an item for selecting whether detailed setting is automatically conducted or not in corresponding IP phones.
3. An IP phone auto configuration method in a system including IP phones, a DHCP server for assigning IP addresses to the IP phones, an FTP server for storing at least one setting data file containing auto configuration setting information for the IP phones, and a network for connecting the IP phones, the DHCP server and the FTP server, the IP phone auto configuration method comprising the steps of:
causing each of the IP phones to acquire an address of the FTP server and a first file name of a setting data file corresponding to the IP phone from the DHCP server after being started; and
acquiring the setting data file from the FTP server when there is a difference between the first file name and a second file name; and
automatically conducting detailed setting in the IP phone based on the setting data file, wherein:
a range of IP addresses used by the DHCP server is divided into a range using a VLAN and a range that does not use the VLAN, and the setting data file stored in the FTP server contains information indicating whether or not to set a VLAN mode;
after being started, each of the IP phones acquires IP addresses in the range that does not use the VLAN from the DHCP server as its own IP address and an address of the FTP server; and
if the setting data file acquired from the FTP server contains information indicating to set the VLAN mode, the IP phone acquires IP addresses in the range that does not use the VLAN as its own IP address and an address of the FTP server again.
4. The IP phone auto configuration method according to claim 3 , wherein the setting data file stored in the FTP server includes an item for selecting whether detailed setting is automatically conducted or not in corresponding IP phones.
