network parameters - yes
press no until you see "change" and press yes.
You will need to set the following appropriately.
IP address, Subnet address, default gateway, ICP controller address, TFTP address, VLAN ID, VLAN priority, DiffServe Value, DNS address.

Normally it is not necessary to set the phone static except for testing. If your network and DHCP server is set up properly, you are not gaining any benefit for setting it static.

Also, you should find out what the other IP addressess are that are static on the Voice subnet. Along with that, you will need to know the DHCP range. These are needed so you don't assign a duplicate IP address to your network. Assign the phone to the wrong device could do great harm to your network. Assign it to use the same IP address as the phone system and none of your phones will operate.

Use with caution,
Mark
