A call waiting deluxe method where a switching system forwards calls to a service node that provides specialized call processing, e.g., processing requiring text-to-speech, to a number of switching systems without requiring modification of the hardware design of those systems. Only calls to busy called stations are forwarded to the service node using a call forwarding-busy line feature to avoid unnecessary delays and excessive service node traffic for normal calls. The service node uses the same directory number that was initially dialed for the call, in invoking a call waiting-originating feature which takes precedence over the call forwarding-busy line feature and results in the transmission of a call waiting signal to the called station. The service node obtains the calling party name from a database and responds to a flash signal from the called station by speaking the calling party name to the called party. The service node also transmits an announcement to the called station including a number of call handling options, and responds to a signal from the called station defining one of the options by controlling handling of the incoming call in accordance with the defined option.
