Abstract:
PROBLEM TO BE SOLVED: To provide a communication apparatus capable of properly performing IP filtering even when communication by IP-FAX is performed when a user inputs the telephone number of the other party. SOLUTION: The communication apparatus which can perform communication by IP-FAX with another device connected to a network includes: an IP filter unit for allowing or rejecting communication on the basis of a set IP address; an inputting unit for inputting or setting a telephone number; and an acquiring unit for acquiring an IP address corresponding to a telephone number input or set by the inputting unit from an ENUM server and an SIP server connected to the network, and sets an IP filter based on the obtained IP address in the IP filter unit.

Abstract:
A computer readable medium having a computer program product stored thereon, the computer program product including instructions for ordering a computer to perform the following steps. The steps include a first receiving step of receiving a facsimile command from a client device configured to executes a facsimile application program, a first determining step of determining whether or not to allow communication with a facsimile device based on a predetermined condition when receiving the facsimile command at the first receiving step, and a transferring step of transferring the facsimile command received at the first receiving step to the facsimile device when the communication is allowed at the first determining step.
Abstract:
A method includes determining whether an incoming call to a first destination is authorized at a switch of a communication network. The method includes, in response to determining that the incoming call is not authorized, determining whether the incoming call is a facsimile call, routing the incoming call to the first destination when the incoming call is not the facsimile call, and routing the incoming call to the first destination when the incoming call is the facsimile call.
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.

Abstract:
A communication device is provided. The communication device includes a call origination unit that originates a call to a communication terminal device; a shift unit that sets as a granted device the communication terminal device to which the call has been originated, and that shifts the communication device to a limit mode in which communication with a communication terminal device which is not set as a granted device is limited, after the call is originated by the call origination unit; and a control unit that determines whether an incoming call is from a granted device when an incoming call is received while the communication device is in the limit mode, that permits communication if the incoming call is from a granted device, and that limits communication if the incoming call is from a device other than a granted device.
Abstract:
Methods and apparatus are disclosed to detect and block fax calls. An example method disclosed herein detects a fax call from a calling number; blocks the fax call if the calling number is associated with a caller to be blocked identified in a database and the fax call is sent to a subscriber; and attempts to identify a presence of a war-dialing technique.
Abstract:
A spam fax filter (120) which has been configured in accordance with the present invention can include a fax transformation processor (180) configured to transform rasterized fax images into non-rasterized representations of fax images. The spam fax filter further can include a knowledge base (150) of known spam characteristics. Finally, the spam fax filter can include a comparator (140) configured to compare non-rasterized representations of fax images produced by the fax transformation processor to the characteristics in the knowledge base to detect spam fax in the spam fax filter.
Abstract:
Disclosed are methods and systems related to ensuring a message is received by the intended entity. The methods and systems disclosed herein overcome this insecure method of transmission through the use of a device that can confirm the identity of a message recipient and additionally can confirm the identity of a message sender. A method implemented by the device is such that upon identification of an unapproved sender or recipient the device will terminate communication, thereby preventing transmission of potentially sensitive information to an unintended party.
