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.
