Ok. Just wanted to eliminate any potential broadcast issues.

routing is minimal in this setup."
I would at least like to have workstations and servers on separate subnets/vlans. Would this setup serve that purpose?
vlan1(default) = workstations
vlan41 = voip
vlan100 = servers
vlan's would be setup across all switches with the core 2824 setup for routing between vlan 1 and 100. A separate WAN router would serve as the default route on the 2824.
