Transfer Type Dropdown There are two transfer types:

Answering Machine Detection

Answering Machine Detection (AMD) determines whether an outgoing call has been answered by a human or a machine (such as a voicemail or answering machine). When AMD is enabled, events are generated in the Flow to indicate the detection result, allowing you to take specific actions based on the outcome.

For example, if a call is transferred to a user and AMD detects a machine, you will receive an event indicating the machine detection.

Parameter Type Description Transfer Type
Answering Machine Detection Toggle Indicates whether a call has been answered by a human agent or a machine. Dial
Redirect on machine detected Selector Redirects the call back to the Flow in case a machine was detected. Dial
Redirect text Text Text to say after machine was detected before going back to the Flow. For example, Mailbox detected, your call will be redirected back to the virtual agent. Please stay in the call. Dial
