US Patent 11991314 Calculating an estimated wait time at a contact center

A server receives a request for communication with a contact center agent device from a user device. The server determines a number of devices preceding the user device in a user queue of devices for communicating with the contact center agent device. The server determines a number of contact center agent devices available for the communication. The server periodically calculates an estimated wait time for the user device as a mathematical combination based on the number of devices preceding the user device, the number of agent devices, and previous wait times of other user devices requesting communications with the contact center agent device. The server transmits, to the user device, an output associated with the estimated wait time.
