I think there was in the past, however, a search on Google for "3cx reports explained" will help you as there are quite a few partners that made their own walkthrough of the reports.Is there a link to a page where I can look at the reports that are available on 3CX rather than running them on trial and error to see what I like? Something with sample outputs?
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
