The first report available under the reporting tab of the navigation is called the Overview Report. Like the name itself, it will show you basic reports from your smrtPhone account, in aggregate.
Here you can find data such as:
Total Talk Time
Average Call Duration
Total Calls by Type
Total Inbound/Outbound Texts
Total Inbound/Outbound calls by Agent
All of the data displayed is taken from the regular smrtPhone dialer itself (that is, not smrtDialer.)
Clients use this report for a high-level view into the activity on the account. It helps to match against billing or to identify areas that need further investigation. We like to think of it as a dashboard of your total account activity.
