Abstract: An apparatus and a method for enabling the originator of a telephone call to send a customized message or signal to an unavailable telephony subscriber on a terminating telephone and to establish a direct operative connection therewith within the same telephone call. The apparatus and method include a Short Message Service device, typically operating in conjunction with a voice mail system and a call forwarding service, for providing the originator of a telephone call to the subscriber with the option of sending a short message to the subscriber's telephone in situations where the subscriber is unavailable. The subscriber may then send a response to the originator and/or choose to establish a direct operative connection therewith within the same telephone call and without requiring either party to place a separate telephone call.
