It appears that from best practices Call Manager should work with a single voice VLAN configuration and some larger scope of DHCP server to support bigger deployments. I wander if you have any suggestions on adding additional voice VLAN into existing Call Manager cluster to add additional and separate DHCP scope from CCM cluster. Whould it be possible and than recommended to CCM expand deployment by adding DHCP scope to allow for additional /24 network and than add additional voice VLAN to allow for such expansion? If yes can you guys suggest the best way to build it on the switches fabric?
I certainly appreciate your advise
