Assigning IP Addresses

SpectraLink handsets operate as LAN client devices and therefore require IP addresses to operate in the
network. IP addresses can be assigned statically through the configuration menus on the handsets or
dynamically using standard DHCP protocol. The Handset Administration Tool (HAT) can be used to quickly
load and change administration options in the handsets, including static IP addresses. For dynamic IP
addressing, a DHCP server is required.
Telephony Gateways and SVP Servers also require IP addresses that can be obtained by either static or
DHCP address assignment. It is always recommended to configure production infrastructure components
with static IP addresses to ensure consistent system access. When using one or more SVP Server(s), (see
Section 4.1.3) the Registration SVP Server must be assigned a static IP address. The Registration SVP
Server is identified by DHCP option 151 to the wireless telephones.
When operating with an IP telephony server (IP PBX), other than Avaya or Cisco, the SVP Server also
requires a range of IP addresses that cover the total number of wireless telephones supported by that SVP
Server. That range of IP addresses is known as First Alias IP Address/Last Alias IP Address in the SVP
Server configuration menu. It is important to note that for redundancy purposes it may be necessary to
assign more IP addresses to an SVP‟s Alias IP range than what the SVP Server would normally support.
