Thank you Jeremy. That will work, I'll ask the client for the IP office IP address. Second question, which is probably a no or at least not best practices. I have a client that has given me one vlan, to use for both voice and data. Let's say 10 devices, all phones, with a pc connected to the back. So, If I tag all the ports, the phones will receive an IP address and see the tag, place the tag on the phone. Question would be would the workstations receive an IP address placed on the back of the phone? I know that if I separate the phone and data connections, I can put the phones on the vlan tagged, the desktop on the vlan untagged and this would work. Thank you.
