PROBLEM TO BE SOLVED: To provide a method and an apparatus that improve how an incoming call is handled across multiple data-processing systems, without some of the disadvantages of the prior art. SOLUTION: Specifically, in a telecommunications call in which a called telephone number is not associated with a particular in-service terminal, an enhanced terminating system of the call refrains from transmitting ringback to the calling terminal until an appropriate event occurs, such as the receiving of an asynchronous response from an auxiliary data-processing system to which the call has been directed. Depending on the response received, the terminating system might refocus the call or provide other treatment to the call. In some embodiments of the present invention, the terminating system also transmits a feedback signal to the calling terminal to provide status to the calling party on the progress of the call attempt, wherein the feedback signal is different from the ringback signal.
