Contact Center - Call Back features

[zoomshoes]

Hi all, I am working through the features of Call-Back in the Menu-based Interrupt. I am wondering how does it integrate with the agents in a queue? What come first? Does Call back place an agent in the queue in a reserved state while it calls back a client? When the client presses one to accept the call back, do they can transferred to the reserved agent? If the client doesn't press one, does the agent get reset back to the ready state for normal calls? What actually happens?
