Abstract: A system and method for non-intrusively displaying telephone call information to a user is used with an existing telecommunications system. The system and method obtains telephone call information, such as automatic number identification (ANI) information, when a telephone call is placed to the telecommunications system. The system and method non-intrusively displays the telephone call information to a user or agent in the telecommunications system, for example, by displaying the ANI information in a title bar of an active window on the agent's workstation. In one example, the system and method uses scripts, such as a bind function script to load an external module, such as a dynamic link library (DLL), and bind a display function from the external module for use in displaying the telephone call information. A display information script obtains the telephone call (ANI) information and displays that information using the display function bound from the external module.
