[Freeswitch-users] callcenter does not exit if all agents are 'In a queue call'

Hello, I'm trying to configured callcenter to exit app and return to dialplan IF all agents are currently on a call. I've tried many different strategies and timeouts to very low (like 1 second) Still the call will sit in the queue. I've tested this in callback mode with an external agent (outbound call) The agent's state is 'In a queue call' This seems like an obvious feature one would need from callcenter, yet I cannot figure out how to configure callcenter this way. Thanks in advance.
