Abstract
A method and apparatus for providing caller ID information related to a third party, to a telephone user already engaged in a telephone call with a second party. A burst of FSK data is transmitted to the user during the conversation with the second party. The FSK data signal is detected and modified as it is received, such as through the addition of a melody, prior to being audibly conveyed to the telephone user. The resulting modified signal is aesthetically pleasing to the user, while indicating to the user that communications with the second party are temporarily interrupted.
