Access Control List for users allowed to access network
There are several ways to do this depending on network size. If you are talking small office/home network, you can filter MAC addresses so certain machines do not get addresses. Larger networks require some version of Network Access Control, either native to your OS or through 3rd party packages.

Can we use a Windows Server 2003 configured as a router to do qos when the switch does not support it?
Short answer: No. If your edge devices do not pass QOS data through to the other end of your calls, all you will accomplish is prioritizing the VoIP traffic internally, on you LAN. If that’s all you want to use the phone system for, then great. I suspect you will actually make outbound calls, and [...]
