Check for Existing Callback V2
This block checks to see if an existing callback already exists for a caller's phone number in the specified virtual queue.
Provide the Virtual Queue and Phone Number that are to be checked for existing callbacks.
If an existing callback with the same phone number is found in the same virtual queue, the Callback Service ID associated with the existing callback is returned, along with additional information such as the request date, request time, and so on.
You can use this tab to store this information in variables.
