I don't think that the Analytics service gives you such detailed info. You may want to check out the Shadow Agent app and contact the service provider to hear more about their product.
Alternatively, you can use RingCentral API to implement your own app to achieve custom calls KPI.
Read this blog (section "Display calls density") to learn more about the call log data. Let me know if you choose this path so I can help you further on how to build an app for your company.
Shadow All In One Analytics has a set of historical metrics that demonstrate queue peak hours, wait times, service levels for any time period (day, week, month).
It also offers a real time dashboard where you can set triggers based on abandonment rate, wait times, etc.
