Assume that the agent is located in Florida. The agent may well belong to a local skillset - non networked, and a also a network skillset. Assume that this agent is the longest idle for both the local skillset and the network skillset and that a call arrives at Michigan, the agent will be reserved to take the call from Michigan. This will prevent the agent receiving a call from Florida. The reservation is necessary since it takes longer for the call path to be switch across a network than it does to switch a call locally. If it were not reserved, a Florida call could sneek in before the network had set up and connected the Michigan call. A call is termed matured when it has been set up connected and answered, well thats what I define it as anyway.
