How to Use Twilio Async Answering Machine Detection

Twilio's standard answering machine detection (AMD) product is used to programmatically detect whether a person or voicemail answered a call. However, it often introduces a delay while processing, creating a lower quality customer experience. To overcome this issue, Twilio offers asynchronous or async AMD, which processes calls in the background and sends the result to a callback URL after the call has been answered. This allows for immediate interaction with the application if a human answers, eliminating the dreaded silence that standard AMD often introduces. The tutorial demonstrates how to use async AMD by creating three TwiML Bins, an async callback function, and an outbound API call script to generate the async AMD-enabled call.
