ABSTRACT:
A system for generating aural announcements of incoming calls within a premises has a premises phone connected within a premises phone line that forms first and second communication channels. The first communication channel is adapted for connection and communication to a phone network. An announcement controller is connected within the phone line and generates aural announcement signals along the second communication channel to a speaker which plays corresponding aural announcements. A switch may be operatively connected between the premises phone and announcement controller and switches the announcement controller into the second communication channel for transmitting aural announcement signals to a premises phone via the switch.
