What is the calculation for the Average wait time?

How do I calculate the Average wait time metric and message?

In Talk, the Average wait time message triggers after the average wait time exceeds two minutes, and it plays once.

In Explore, the Average wait time metric displays on the Zendesk Talk dashboard:

Calls that wait in the queue after they pass the initial greeting, under Current queue activity

The full day from 00:00 to 23:59, under the Overview table

The Average wait time metric includes all calls that pass the initial greeting and averages their wait times over a 24-hour period.

To confirm that the average wait time exceeds two minutes, check the metric with the same name under the Overview table. The system queues the message by each line's Average wait time metric.

Note: The Average wait time metric under Current queue activity is a real-time calculation of activity in the queue, and it doesn't indicate when the Average wait time message criteria are met.
