Here is the scenario. I have an IP 403 connected to a cisco 24 port switch. I have 10 computers connected with ip's 10.40.0.xxx. The office is set up via standard LAN, with file servers, DHCP etc. I want to add 10 ip phones 4612's and 24's to the same cat5 wire to the desktop. Now I know that the phones have only hubs in them, but do I need Vlan's? How can i have the 10.40.0.xxx for the computer and 10.40.0.xx a different ip address for the phones? If I do need vlan's how is this set up via the Ip office?
