The TFTP server and the SIP TFTP server may be the same device 
with the same IP address or may be different devices with 
different IP addresses. 
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 only APs 
on the new subnet. 
Syslog Server IP
  The IP address of the syslog server. See Chapter 5 
Diagnostic Tools for more information. 
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.   
The TFTP server and the SIP TFTP server may be the same device 
with the same IP address or may be different devices with 
different IP addresses. 
OAI Server IP 
 The IP address of the SpectraLink OAI Gateway. If 
using Static IP configuration, this is simply the IP address of the 
SpectraLink OAI Gateway. If DHCP is being used, the handset 
will try the DHCP option 152.
