Call queue-to-queue overflow allows scalable management of inbound calls during heavier-than-usual or peak-season inbound call activity. You can append existing queues to the original queue, so if all lines are busy in the original queue, calls overflow to additional queues.
Call handling follows the call queue policy. Call queue overflow is supported for the Rotating and In Fixed Order sequence protocols. The Simultaneous protocol is not supported.
The Overflow Call Queues section lets you enable, create, and manage your overflow queues.
