# Sample queued callback flow in Amazon Connect
<a name="sample-queued-callback"></a>

**Note**  
This sample flow is available in previous Amazon Connect instances. In new instances, you can see examples of queued callback in [Sample interruptible queue flow with callback in Amazon Connect](sample-interruptible-queue.md) and [Sample queue configurations flow in Amazon Connect](sample-queue-configurations.md).

Type: Flow (inbound)

This flow provides callback queue logic. Here's how it works: 

1. After a voice prompt, a working queue is selected and its queue status is checked.

1. A voice prompt tells the customer if the wait time for the selected queue is longer than 5 minutes. Customers are offered a choice to wait in the queue or to be placed into a callback queue. 

1. If the customer decides to wait in the queue, the **Set customer queue flow** block places them in a queue flow that provides a callback option. That is, it places them in **Sample interruptible queue flow with callback**. 

1. If the customer chooses to be placed into a callback queue, their number is stored in the **Store customer input** block. Then their callback number is set, and they are transferred to the callback queue.
