# ANSWERING_MACHINE_DETECTION

> This event detects whether a call is answered by a human or machine on outbound calls.

The call was initiated and the Answering Machine Detection (AMD) process started.

To test a payload with this Node:

1. Create a Flow.
2. Add a **Transfer** Node.
3. In the **Dial** type of the **Transfer** Node, activate the **Answering Machine Detection** setting.
4. Click **Save Node**.
5. Below the **Transfer** Node, add a **Lookup** Node.
6. In the **Lookup** Node, select the **Call Event Status** type.
7. In the child **Case** Node of the **Lookup** Node, select the **Answering Machine Detection** call event status.
8. Click **Save Node**.

When the user receives the `ANSWERING_MACHINE_DETECTION` event, the Flow will seamlessly continue:

* If a machine is detected, the call can be routed to a pre-recorded message with self-service options.
* If a human agent is detected, the call will proceed as usual, ensuring personalized assistance.
