Abstract

The present invention describes an apparatus for use in a telephone network having a calling station connectable to a first switch means and a called station connectable to a second switch means, with the first and second switch means being connectable by a link. Generally, the apparatus comprises an interface having a passive in-line monitor connected in the link for detecting entry of a predetermined service access code by a user of the calling station or a user of the called station after call completion between the calling station and the called station and before either of said users goes on-hook. Upon entry of the predetermined service access code, a speech circuit of the apparatus issues a predetermined prompt to the user of the calling station and/or the user of the called station. Processor control circuitry of the apparatus is then responsive to entry of predetermined signaling by one of the users following the issuance of the prompt for providing a predetermined service controlled and paid for by the user requesting the predetermined service. Alternatively, if the parties are familiar with the service offering, the prompt is not required.
