Abstract: An apparatus transmits information, by a communications network, to any one of a plurality of communication terminals connected to the network in response to a failed communications attempt by any one of the terminals. The apparatus comprises: an identification facility for identifying a network address of a terminal making a failed communications attempt, at least one data storage for storing a plurality of network addresses so identified, and an information transmission facility for transmitting information to a terminal making the failed communications attempt. The information transmission facility is adapted to access the data storage facility, to locate a network address stored therein and to transmit the information to a network address so located.

Abstract: An interactive information delivery system server delivering text or other visual data to a display unit is accessed by a user by means of his own telephone, through an interface unit. The interface unit interprets key pad presses and/or voice commands, and in response to these it controls the server. This allows the expensive and vulnerable hardware (which may be a conventional PC and modem) to be positioned in a secure location, but still be usable by members of the public. As the location of the display unit (which may be a conventional PC and modem) may make audio output impractical, the interface unit may pass an audio channel from the server to the user's telephone. In response to appropriate commands from the telephone, it can also divert the call to a predefined call centre.

Abstract: An interactive information delivery system server 2, delivering text or other visual data to a display unit 3 is accessed by a user by means of his own telephone 6, through an interface unit 1.
