That's a great question.
The option that offers a callback in queue plays every 5 minutes and that means if you call at 10:45 and you wait until after 11pm for the callback option, it will no longer be available to you.
Also, our callback system will simply not offer callbacks between 11pm-8am, which means it won't allow you to subscribe to a callback, but callbacks can be performed between these times.
If you call at 5pm and you select a callback for 11:30pm, it will call you then. If you call at 11:30pm, you won't get an option to take a callback.
Hope this clears things up. If I misunderstood your question, please let me know
