Abstract: In an audio-digital telephone interface system, selective operation prompts a caller with oral instructions to provide: digital control signals, digital data signals (numeric) or audio signals. Inbound and outbound operations are involved and inbound callers are qualified as by automatic number identification (ANI) signals and consumable key operation. A data cell is loaded in accordance with an operating program and the resulting data packet is flagged depending on the presence of audio signals. Data packets are returned to storage, as for subsequent addressing to call up, as to process or cue a caller. The illustrative format receives and organizes order data for goods or services or to isolate a subset or a sub-subset of callers.
