The present method and system provides for call center simulation including receiving a plurality of input parameters relating to call center operations, wherein the call center operations include a main queue for processing on-hold calls and a virtual queue for processing a plurality of call back requests. The method and system further includes generating a call arrival dataset based at least on the plurality of input parameters and simulating call center operations for managing the call arrival dataset across the time sequence, including placing a portion of the call arrival dataset into the virtual queue. The method and system includes simulating a metering of the call arrival dataset in the virtual queue for a metered wait time based at least on a queuing factor and generating a simulation output indicating operations processed via the main queue and the virtual queue.
