Apparatus for a telephone switch, e.g. a tandem switch, for providing a telephonic mass announcement service and methods for use therein in providing passive and/or interactive announcements as well as interactive mass announcement based custom call routing services. Specifically, mass announcements are provided by connecting an announcement circuit as one input to a time-space-time (T/S/T) switch located within a tandem telephone switch and permitting the central processor that controls the tandem switch to establish a time slot connection between that circuit and any caller. Digitized announcements are stored in a main announcement store contained within the tandem switch. Operationally, the central processors respond to each incoming call for a specific announcement by establishing a time slot connection between that announcement circuit and the caller through the T/S/T matrix switch, downloading this announcement from the main announcement store into the announcement circuit and thereafter instructing the announcement circuit to play the announcement over the time slot connection to the caller, and specifically over the caller's "receive" leg of the "four-wire" path established through the T/S/T switch. For interactive mass announcements, the central processor connects a DTMF receiver to a time slot connection established through the T/S/T matrix switch to the caller's "transmit" leg of this "four-wire" path in order to obtain a digit(s) entered by the caller during playback of the announcement. During an interactive announcement, the announcement circuit executes a specific script, typically involving a decision tree contained therein, associated with the announcement and, in response to the entered digit(s).
