We would like to generate a report that shows the number of voice messages that have been generated over a time period e.g. 1 month

The only place i can see this is visable to from the following screen

www.site24x7.eu/app/client#/home/operations/alert-logs

This will only display a days worth of alert data.

Would it be possible to show alerts over a data range.

This would be extremely useful to identify how many out of hours call outs have been generated over the course of a month.
