While our products will work perfectly when installed directly on the 3CX server, we strongly urge you to install our tools on a separate server when feasible. 3CX Support does not like anything extra installed on the 3CX server. This includes SQL Server, Internet Information Server, anti-virus software and our tools. If you need help from 3CX support, they will ask you to remove all non-3CX software PRIOR to providing assistance. Uninstalling software may delay assistance from 3CX and could require significant labor to uninstall and reinstall our tools.
