# Sample interruptible queue flow with callback in Amazon Connect


**Note**  
This topic explains a sample flow that is included with Amazon Connect. For information about locating the sample flows in your instance, see [Sample flows in Amazon Connect](contact-flow-samples.md). 

Type: Customer queue

This flow shows you how to manage what the customer experiences while in queue. It uses **Check contact attributes** to determine if the customer is contacting you by phone or chat, and to route them accordingly.

If the channel is chat, the customer is transferred to the **Loop prompts**.

If the channel is voice, the customer hears a looping audio that interrupts every 30 seconds to give them two options from the **Get customer input** block:

1. The customer can press 1 to enter a callback number. Then the **Get customer input** block prompts the customer for their phone number. Then the flow ends. 

1. Press 2 ends the flow, and the customer remains in the queue.
