Depending on the configuration requirements, you can change
the IP Phone 2001 configuration to allow the following IP address
assignments:

• Full DHCP— (default) all parameters are obtained from the
DHCP server
A DHCP server and DHCP relay agents must also be installed,
configured, and running if you choose Partial DHCP, or Full DHCP
