* Use DHCP Will use Dynamic Host Configuration Protocol to assign an IP
address each time the handset is turned on. If DHCP is enabled, the handset also
receives all other IP address configurations from the DHCP server.
Static IP Allows you to manually set a fixed IP address. If selected, the handset
will prompt for the IP addresses of each configurable network component.
When entering addresses, enter the digits only, including leading zeroes. No
periods are required.
Regardless of the mode in which the handset is operating, the following
components must be configured in the system:
Phone IP The IP address of the handset. This is automatically assigned if DHCP
is used. If using Static IP configuration, you must obtain a unique IP address for
each phone from your network administrator.
Default Gateway and Subnet Mask Used to identify subnets, when using a
complex network which includes routers. Both of these must be configured
either with an IP address under Static IP (not set to 000.000.000.000 or
255.255.255.255) or with DHCP for the handset to contact any network
components on a different subnet. If configured on the DHCP server, use
option 3 for the Default Gateway and option 1 for the Subnet Mask. Contact
your network administrator for the proper settings for your network.
 Note that the handsets cannot “roam” across subnets, since they cannot
change their IP address while operational. Ensure that all your APs are
attached to the same subnet for proper operation. The handset can change
subnets if DHCP is enabled and the handset is powered off then back on
when within range of APs on the new subnet.
