Abstract

A method and apparatus for producing an audio tag in response to calling line identification information. The method includes the steps of, receiving calling line identification information from a telephone line, searching a directory, using at least some of the calling line identification information as a search parameter to locate a directory record corresponding to at least some of the calling line identification information, communicating information held in the directory record or in the calling line identification information to a text to speech converter to produce the audio tag.
