Abstract
Abstract A telephone subscriber of a privacy communications service is allowed to use a randomly selected non-assigned telephone number--instead of the subscriber's real telephone number--as a return phone number in a telephone message left for a called party. The non-assigned, randomly selected telephone number becomes inoperative after a threshold that may be pre-imposed by the subscriber is exceeded. According to a feature of the invention, the function of randomly selecting a non-assigned telephone number may also include replacing the calling party number with the randomly selected number. Hence, when a caller-id display unit receives the telephone number of an incoming call for which the privacy communications service is used, the randomly selected telephone number--as opposed to the real telephone number--is received and recorded by the caller-id display unit.
