Issue with ShoreTel ip480 series phones and Netgear switches
We have a ShoreTel phone system which is currently working with IP230 model phones. The ShoreTel server and the DHCP server are virtual machines running on VMWare 5.5. Everything related to the phone system is connected using Netgear FS728TP switches.
I recently tried to add some IP480 series phones to the system without success. The new phones will not pick up an IP address from the DHCP server. I will be adding more of these phones in the near future and I do not want to have to manually configure each one and manually track IP addresses. If I manually configure them they work fine.
I looked on line and found several references to similar issues being resolved by tagging the VLAN on the Netgear switches. I tried assigning all the ports on the switch the ShoreTel appliances, DHCP server and ShoreTel server are connected to without success. I changed the PVID for all the used ports to the VLan ID on the Netgear switch and configured VMWare to use the same VLanID.
Once I was done the IP230 phones could still get an IP address but the IP480 series still failed. I tried connecting a computer and it pulled in an IP address as well.
I have included screen shots of the configuration pages for the Netgear switch and VMWare.
Ports 1-6 on the switch are reserved for the appliances. Ports 21-24 are connected to the VMWare servers. The rest of the ports are used for phones. There are additional switches but I just used this switch for testing since everything is plugged into this switch.
Can anyone see what I have missed?

The Netgear routers are used exclusively for the phone system there is no data network on them. They were setup before i started with vlan 600 for VOIP. Currently our DHCP server has a scope set for the network card attached to the netgear switches which has ioption 156 set and it works fine for all of our current 200 series phones.
Is your DHCP server on the same subnet?
ASKER
The ip of the network card connected to the Netgear switches is on on the same subnet
Have you tried adding a DHCP Helper, I was able to replicate the fault by removing the DHCP helper even when it was on the same Subnet.

I dont think I can add a DHCP Helper on the Netgear FS728TP switches.

I managed to get the phone to configure by using the configuration above and manually setting the VLAN on the phone to 600.
