Hi All: I just bought a Dell PowerEdge 1750 (dual processors and RAID) to run a 3cx phone system on and was looking to have something cleared up. I will have about 40 users (phones) and will get a 16trunk license for 3cx but was unsure as to which OS I should install on the new box. I currently have extra licenses for XP and Windows 2000 and Vista Business but nothing for Server 2003 or 2008. Dell has hardware drivers available for Windows 2000, server 2003 and 2008. I am trying to avoid buying additional software licenses but wanted to see if anyone else here had 3CX running on a Dell 1750 OS other than a server OS. Will 3CX run ok on Windows 2000? Thanks in advance for looking.
