Systems and methods for allowing a call center to accept and schedule callback appointments for the service of inbound calls at times which are convenient for the inbound caller as well as automatically placing an outbound call at the scheduled callback time. The system collects information from the caller when scheduling a callback time which assists the agent with servicing the scheduled callback more efficiently than the original incoming call. The system also uses algorithms and various system parameters to determine how many agents are needed to service all scheduled callbacks at a given time while maximizing the efficiency of the agents by avoiding having agents service callbacks which fail to reach the person to be serviced for various reasons. When not enough agents are available to handle the scheduled callbacks and current incoming calls the called back individual is automatically connected to the next available agent avoiding the line of incoming calls entirely. This results in not only increasing the efficiency of the agents it also decreases the time necessary for the call center to provide for the scheduling of future callbacks.
