Call Analytics by Forwarding Number
You can view your call volume separated by forwarding number if you use more than one. To review these statistics, expand the "Call Analytics" category in the column on the left of your online portal and select "By Forwarding Number" from the list.
This will bring you to the analysis screen. You can change the date range by clicking on the date box on the upper right of the screen. All of your numbers will be selected and displayed by default. You can look your telephone numbers individually by clicking on the drop-down box that states "All Numbers" on the upper left. Likewise, you can narrow down the forwarding numbers you are analyzing by using the "filter by Calls and Filter by Forwarding Number" drop-down just to the right. There is also an option to filter by "Duration" with the final drop-down.
The graph will show the unique callers in blue and display a total. It will also separate callers who have dialed in before in yellow and display the total. If the call volume is too small to view relative to another number's you can hover over that portion of the graph and a bubble will appear displaying the information.
