Twilio's Answering Machine Detection (AMD) solution has been made generally available, providing businesses with the ability to tailor their outbound call flows according to how they are answered. The solution improves customer call experience by identifying whether a human, machine, or fax is answering the call, allowing for more effective workflow automation. With AMD enabled, Twilio will return an 'AnsweredBy' parameter in the webhook issued to the URL of the outbound call request, indicating whether a human, machine, or other type of party answered. The solution has been built on a new underlying engine that offers higher predictability than its predecessor and includes optional API tuning parameters to adjust performance for specific use cases. These parameters allow customers to fine-tune the solution to their specifications, determining performance tradeoffs right for their unique requirements. Twilio's AMD is available at $0.0075 per call where it is enabled and if the called party successfully answers, with pricing based on successful calls only.
