    Is see that it's not recommended that "3CX Phone System must not be installed on a host which is a DNS or DHCP server, has MS SharePoint or Exchange services installed." https://www.3cx.com/docs/manual/installation-windows/

    Why is this, exactly?

    Has anyone ran into issues with the DNS and DHCP roles causing issues with 3CX?

    In earlier versions -- 11, 12 it was possible and almost recommended to use the Windows server for DHCP for IP phones. Not clear why policy changed now (with versions 14, 15) ?

    I use DHCP to provision the phones with Option 66 on all my 3CX servers without issue.
