Abstract

A method for use in a telephone system, permitting a caller connected to a central platform to further attempt to reach a subscriber after the central platform initially attempted to establish a connection with the subscriber by dialing the subscriber's number and the subscriber's telephone was detected as being in either a Busy/No answer (BNA) condition or a Ring/No answer (RNA) condition at the subscriber's telephone station. Upon detection of either a BNA or RNA condition, a determination is then made as to whether an option associated with the detected condition is available for the subscriber. If an option is available and is selected by the caller, the subscriber is paged and the initial attempt to establish a connection with the subscriber from the platform is terminated. The caller is then informed of the progress of the further attempt to reach the subscriber by prerecorded messages associated with the detected condition. The subscriber is then redialed by the central platform, saving the expense of a separate telephone call.
