The maximum listing in the call log is only 90 days, in case we're wondering
1 or 2 years of incoming and outgoing calls without a calendar, how will it be possible to see this?
@Tedo1978 - Depending on your version of 3CX you may not be able to run a suitable call report. If you need to keep call records for up to 2 years (or more) then, if possible, I'd suggest you enable CDRs and start collecting the resultant call data.
