Hi Sergio,
It seems that our documentation needs a bit updating, do you have the link to the article you are referencing below? The article that bests described how scheduling a callback works is listed here:
https://help.mypurecloud.com/articles/schedule-a-callback/Basically the agent has 2 options: 1) Just schedule the callback for the queue which means anybody in the queue can be getting the callback or 2) ACD will try to route the conversation back to the user who scheduled it. Keep in mind that that if the user is not available to take the conversation when the scheduled time has expired the callback will be routed to the next available agent in the queue.
In the future we plan some enhancements to allow you more control about how long a callback should wait for the agent to become available before routing to the rest of the queue when using the 'Route Callback to me if possible' option.
Hope this helps?
Regards,
Jeroen
