How can an Admin determine to whom and how frequently SMS and Voice calls are being used?

[C.W.]

We are encountering additional costs for SMS and Voice calling in our instance that we would like to mitigate by target training the individuals who are using the most calls/SMS rather than creating a blanket rule that affects all users of the same permission set. 

How can I visualize to whom and how frequently specific users are electing to receive SMS and voice calls over using the app notification options? Is there a function that allows me to pull a dataset on alerts and notification methods based on criteria such as "number of SMS received in T-time period" or "number of Voice calls received in T-Time period?"

Hi @C_W_ 

Opsgenie have couple of default reports that might be useful here like On call per user

Did you maybe try them?
