Dialing - Answering Machine Detection
The Answering Machine Detection settings allow you to configure parameters relating to answering machine detection.
Note The Dialing options are only available when a dialer is installed on the server.
IBM SPSS Dialer supports a simple answering machine detection (AMD) that can be useful when dialing residential numbers. It is based on the observation that human greetings are usually short, whereas answering machine messages are long. When an auto-dialed participant record is dialed, and IBM SPSS Dialer detects that an answering machine picked up the call, the call is automatically ended with the Answering Machine call outcome when the UNICOM Intelligence Interviewer - Server Admin is properly configured to support the feature. Answering machine detection is currently configured through the DPM Explorer tool.
