Is there anyone out there who has implemented an IP telephone system. We're going to be moving to a new IP telephone system and typically IT Services are the last ones to find out. The supplier has asked us to add the following information to our DHCP server.

ID: 128
Name: Nortel IP Terminal Information
String: Nortle-i2004-A,,1,10

ID: 144
Name: ip2004 dhcp
String: VLAN-A:2.

I can't find any options where I can insert this information. Do I need to create a new DHCP option for a new Vendor Class Identifier?

If so how do I do this please?

Any advice or suggestions would be very gratefully received.
