Two DHCP scopes, one vlan

We currently have one vlan for our voice and data network with one dhcp scope. We are wanting to keep the one vlan setup and we want to have our voice devices pull from one scope and our data devices pull from another. Currently they are both pulling an address from the same scope. We don't want to put static ip's on 300 devices for our vioce network, but we do want them to all pull an address in a certain range so we can monitor that range. Any suggestions? We are a 2003AD shop with a cisco network.

Work with MAC addresses. Chances are all your VoIP phones are made by the same manufacturer, so have your DCHP server hand out addresses from that manufacturer's MAC range one IP range, and all others to another.

I was thinking the same thing but I don't know how to set up a scope that way.

I found one guide here that will let you assign a specific IP to a specific MAC address, but if you have a lot of VoIP hosts, it will be tedious.

I will look for something that will work with a MAC address range.

I haven't been able to find anything to do a whole range, doing reservations for every single device is out of the question!
