SpectraLink 8002 Wireless Telephones Configuration and Administration (SIP) 
28 
PN: 1725-36034-001_B.doc 
 
Dynamic Host Configuration Protocol (DHCP) is a standardized 
protocol that enables clients to be dynamically assigned with various 
configuration parameters, such as an IP address, subnet mask, 
default gateway, and other critical network configuration information. 
DHCP servers centrally manage such configuration data, and are 
configured by network administrators with settings that are 
appropriate for a given network environment. The handset will use 
the following DHCP options if DHCP use is enabled.

siaddr 
Boot server or next server 
Static IP 
 Allows you to manually set a fixed IP Address. If selected, the 
handset will prompt for the IP addresses for each configurable 
network component. When entering addresses, enter the digits only 
including leading zeroes, e.g. 192.168.001.002. No periods are 
required. 
Regardless of the mode in which the handset is operating, the 
following components are required and must be configured as part of 
the SIP 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 handset from your 
network administrator.  
TFTP Server IP
  The IP address of a TFTP server on your network, 
which holds software images for updating the handsets and 
contains the handset files. If this feature is configured (not set to 
0.0.0.0 or 255.255.255.255) with either Static IP configuration or 
using DHCP option 66 (TFTP server), or the boot server/next 
server (siaddr) field, the handset will check for newer software 
each time it is powered on or comes back into range of your 
network. This check takes only a second and ensures that all 
handsets in your network are kept up-to-date with the same 
version of software.
