Enterprise-wide split function IVR callback system

A system related to connecting customers to agents of a business includes an inbound (INB) interactive voice response (IVR) computer, an outbound (OUTB) IVR, and a computer telephony interface (CTI) computer. The INB IVR computer receives an inbound call from a customer and determines that there is a delay in a call queue of a call center. The OUTB IVR places an agent outbound call (on behalf of the customer) to the INB IVR which is then placed into the queue of the call center in response to the customer selecting a call-back option. The CTI computer then monitors the call center, and sends a notification to the OUTB IVR processor in response to the agent outbound call connecting to the available agent. Responsive to the notification, the OUTB IVR computer places a customer outbound call to the customer to connect the customer to the available agent.
