Snippet: Queue Callback Request

This snippets will show you how to request a callback from a voice call or text message so you can have your customers keep their sanity, while avoiding long hold times by offering this useful option. Customers can call and request a callback by pressing a digit, or they can text message the number and request a callback when the next agent is available.

You will need a machine with Python installed, the SignalWire SDK, a provisioned SignalWire phone number, and optionaly Docker if you decide to run it in a container.

For this demo we will be using Python, but more languages may become available.

SignalWire SDK
