摘要： An apparatus and method are disclosed that enables detecting the spoofing of a telephone number. To validate the identity of a calling terminal, some techniques in the prior art rely on exchanging data that only the legitimate calling system and the called system know about. In contrast, the illustrative embodiment of the present invention validates the identity of the calling terminal by assessing characteristics other than the calling terminal's telephone number, such as the telephone type and the signaling protocol. By using characteristics other than telephone number to validate the identity, the data-processing system of the illustrative embodiment makes it more difficult to spoof a legitimate telephone's number.
Application is for SIP telephones to chekc whether received header data is consistent with knowledge at the receiver side. Should the data be inconsistent then the assumption is that the caller ID has been spoofed.

摘要： A technique is disclosed that changes one or more properties of a user interface at a telecommunications terminal based on an incoming call. When a first caller calls the telephone number of the terminal directly and the terminal answers the call, the terminal presents the direct call to the user through a first user interface. When a second caller calls a telephone number that is associated with a data-processing system and the call is then redirected to the terminal, the terminal presents the redirected call to the user through a second user interface. The telecommunications terminal can be a cell phone that belongs to a user, and the data-processing system can be a private branch exchange that serves an office enterprise network that the user belongs to, wherein the private branch exchange extends the call to the user's cell phone when the user is out of the office.

摘要： A method and an apparatus are disclosed that manage the held calls for an off-premises terminal at the system that extends calls to the terminal, such as a private branch exchange or other type of data-processing system, instead of at the system that is receiving the extended calls, such as a mobile switching center at which a cell phone is registered. The disclosed technique is based on the observation that the extending system knows of an incoming call to an off-premises terminal before the receiving system. As a result, the extending system can advantageously select the calls that it holds versus the calls that it sends to the receiving system. The extending system can control the routing costs and provide a consistent look-and-feel of call control to the off-premises terminal user.

摘要： A method and apparatus are disclosed that enable a user who is on a call using a call appearance at a first terminal to continue the call on a call appearance at a second terminal, wherein the second terminal has been excluded from the call. In the illustrative embodiment of the present invention, a private branch exchange that handles both telecommunications terminals receives a first signal that indicates that the first terminal has disconnected from the call. The private branch exchange then receives a second signal that indicates that the second terminal has gone off-hook or otherwise indicates a request to be added to the call. If the private branch exchange has received the second signal within a predetermined time interval after having received the first signal, then it adds the second terminal to the call.
