Abstract
A communication apparatus that enables to appropriately perform IP filtering even when communication via a network is performed by a user inputting a destination phone number. An IP filter permits or rejects communication on the basis of a set IP address. An input unit inputs a phone number. An acquisition unit acquires an IP address corresponding to the phone number inputted by the input unit from a server connected to the network. A setting unit sets the IP filter so that communication using the IP address acquired by the acquisition unit is permitted.
Claims7
A communication apparatus capable of communicating with other communication apparatuses connected to a network, the communication apparatus comprising:
- an IP filter configured to permit or reject communication on the basis of a set IP address;
- an input unit configured to input a phone number;
- an acquisition unit configured to acquire an IP address corresponding to the phone number inputted by said input unit from a server connected to the network;
- and
- a setting unit configured to set said IP filter so that communication using the IP address acquired by said acquisition unit is permitted.
A network system including a plurality of communication apparatuses and servers, each communication apparatus comprising:
- an IP filter configured to permit or reject communication on the basis of a set IP address;
- an input unit configured to input a phone number;
- an acquisition unit configured to acquire an IP address corresponding to the phone number inputted by said input unit from the server;
- and
- a setting unit configured to set said IP filter so that communication using the IP address acquired by said acquisition unit is permitted.
A control method for a communication apparatus capable of communicating with other communication apparatuses connected to a network, the control method comprising:
- an IP filtering step of permitting or rejecting communication on the basis of a set IP address;
- an input step of inputting a phone number;
- an acquisition step of acquiring an IP address corresponding to the phone number inputted in said input step from a server connected to the network;
- and
- a setting step of setting the IP filter so that communication using the IP address acquired in said acquisition step is permitted in said IP filtering step.
