SVP Server IP The IP address of the NetLink SVP Server. If using Static IP
configuration, this is simply the IP address of the NetLink SVP Server. Note that
the NetLink SVP Server must be statically configured to have a permanent IP
address. If DHCP is being used, the handset will try the following, in order: the
DHCP option 151, then a DNS lookup of “SLNKSVP2” if the DHCP options 6
(DNS server) and 15 (Domain Name) are configured.
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.
SIP TFTP Server IP The IP address of a TFTP server on your network, which
holds SIP configuration files. In static mode, this parameter must be configured
with an IP address. In DHCP mode, the SIP TFTP server may be specified by
defining the address on the DNS server for the name “siptftp” If this is not
defined, the address specified in option 66 will be used. See Section 5, SIP
Integration Factors.
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 the
network administrator for the proper settings for the network.
 Note that the wireless telephones cannot “roam” across subnets, since they
cannot change IP addresses while operational. Ensure that all 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.
Syslog Server IP The IP address of the syslog server. See the Diagnostic Tools
section for more information.
OAI Server IP The IP address of the NetLink OAI Gateway. If using Static IP
configuration, this is simply the IP address of the NetLink OAI Gateway. If
DHCP is being used, the handset will try the DHCP option 152.
ESSID
Select the option that will enable the handset to acquire APs with the correct ESSID
(Extended Service Set ID, aka SSID) each time it is turned on.
Note about Automatic Learn options: Broadcast ESSID must be enabled in the APs
for ESSID learning to function. Refer to the Configuration Note for specific APs or
call the AP vendor for specifics. Overlapping wireless systems complicate the use of
ESSID learning as the handset in an overlapping area could receive conflicting
