Abstract
A Calling Number Display and Recording System stores caller identification (CID) information (148) including a caller's telephone number and other pertinent information when a called party is not present and records the CID information (148) verbally for later replay or other use. The system integrates customer-owned telephone equipment (12, 17) with CID information (148) placed on a telephone carrier (144) by Central Office equipment. A calling party termination signal, known as a "Wink" signal (146), is used as a trigger to disconnect an answering device (17) from a telephone line (14) and to place decoded CID information (148), which is processed by control logic (38), at the end of any message (155) left by the caller. The processed information (76) may be displayed visually and announced by a voice synthesizer.
