Call Center routing adjustment: overflow

Choose the image that looks most like your screen once logged in.


Overflow adjusts call routing for callers in the queue by signaling a specified action after a certain time. If a queue receives a large number of calls and the callers are waiting for more than the predefined waiting time, the overflow feature will trigger.

Overflow can be beneficial if there is a long wait time and can be configured to move Overflow calls from a busy Call Center to one that has more availability, to improve the Call Center experience. If your Call Center Queue Length has been reached and another call comes in, Overflow will be triggered and follow the routing policy configured in the steps below.


To Adjust Overflow Settings:

From the Nextiva Voice Admin Dashboard, hover over Advanced Routing and select Call Center Locations.
