My company wants to install Nortel 1120E IP phones and according to Nortel you have to create a option 128 in DHCP, but they cannot tell me how to do this? Have anyone setup this before?

Ok, the answer is:

On the DHCP main page, right click your server and select "Predefined Options".

Add a new class:

Class: Global
Name: Voice Vlan ID
Data Type: String
Code: 128
Description: Voice Vlan ID

This can now be used for future reference.
