This report style is for use only in conjunction with the "Real-Time" date/time option. The report content generated displays a live list of the active calls on the telephone system. The reporting style shows no information when run against any other date/time option.
Note that on Akixi 3000 configurations, this report can also display email and LiveChat contact items, assuming the correct Omnichannel integrations have been configured by the administrative user. This works much the same way as with calls, and will show emails and LiveChat items being actioned or alerting at any given point.
