DHCP: Different Details for Different Devices

Is there a way using the Windows 2000 Server DHCP service, or any other DHCP
service to issue out different parameters depending on the requesting device
MAC address (i.e. manufacturer).

We Have in our network 2 types of VoIP phone, connected to 2 different call
managers. One is Avaya, the other is Cisco. Neither can talk to the others
call manager so can only talk to its own company.
So we want to using DHCP give one set of parameters to the Cisco phones,
another set to the Avaya phones, and the basic parameters to the PC's.

I have done a Google search and found references to Vendor settings for
DHCP, but no examples of how its actually done. So I am putting out a cry
for help to you experts to see if it can be done, and how.

What exactly do you want to be different?
If it's just the options like the DNS servers, default gateway, etc., but
you want the same TCP/IP network, you could perhaps set up multiple scopes,
and set the options per scope, not per server. In the phone scopes, use only
DHCP reservations per MAC address and don't have any unreserved addresses
available.
For your workstations, set up the scope as you wish. I think this should
work unless I'm missing something.

Things that need to be different, are Gateway address, TFTP server, MCCID,
Call Server. The second 2 are set using a custom DHCP parameter 174, which
needs to be added.
I had forgot I could have different scopes, will try this tomorrow. However
I would have preferred it if I could send parameters using the vendor class.
I need to do more research on this. As far as I can remember the Vendor is
set by the first 6 bytes of the MAC address
