The reports you may find particularly useful on a regular basis include the Client Report, Call Detail Report, and the Top 20 Call Report. All these reports are available either directly from the Reporting menu (for example, Reporting > Client Report) or from the Graph Builder page (Reporting > Graphs).
On these pages, you can choose from preset criteria (for example, Today and Last 7 Days), select a custom range, or you can use advanced filtering to create a report that focuses on the information in which you are interested.
All reports, including those you tailor to your needs, can be memorized (filtering criteria saved) to avoid having to re-enter previous reporting criteria. Create easily-recognizable, unique names to identify your custom reports.
