Flow types

You can use this block in the following contact flow types:

  • Outbound Whisper flow


Outbound whisper flows run in Amazon Connect immediately after an agent accepts the call during direct dial and callback scenarios. When the flow runs:

  • The caller ID number is set if one is specified in the Call phone number block.

  • If no caller ID is specified in the Call phone number block, the caller ID number defined for the queue is used when the call is placed.

  • When there is an error with a call that is initiated by the Call phone number block, the call is disconnected and the agent is placed in AfterContactWork (ACW).

Only published flows can be selected as the outbound whisper flow for a queue.


To use a custom caller ID, you must open an AWS Support ticket to enable this feature. For more information, see Set up outbound caller ID.
