WLAN Handsets 2210/2211 configuration
• Server 1 Port – the UDP port number used by the wireless handset to
contact the LTPS Node Connect Service to request registration with the
LTPS and the Call Server. If the wireless handset is using static IP
address configuration, enter port number 4100. If the WLAN handset is
using DHCP, the DHCP server must be configured to provide the TLAN
node IP address and UDP port number of the LTPS IP Telephony Node
on the Call Server using one of the following DHCP options:
46, 128, 144, 157, 191, and 251.
The following components can be configured optionally:
• TFTP Server IP
which holds software images for updating the wireless handsets. If this
feature is configured (not set to 0.0.0.0 or 255.255.255.255), either
through Static IP configuration, through using DHCP option 66 (TFTP
Server), or the Boot server/next server (siaddr) field, the wireless handset
checks for different software each time it is powered on or comes back
into range of the network. This check takes only a short time and ensures
that all wireless handsets in the network are kept up-to-date with the
same version of software.
Note: It does not matter if the software version on the TFTP Server is
newer or older; if the versions are different, the wireless handsets
download the software from the TFTP Server.
• OAI Server IP – the IP address of the WLAN Application Gateway
2246 (if using). If using Static IP configuration, this is simply the
IP address of the WLAN Application Gateway 2246. If DHCP is being
used, the wireless handset tries DHCP option 152.
• Default Gateway and Subnet Mask – used to identify subnets, when
using a complex network which includes routers. Both of these fields
must be configured (not set to 0.0.0.0 or 255.255.255.255) to enable the
wireless handset to contact any network components on a different
subnet. They can be configured using Static IP configuration or through
DHCP options 3 (Default Gateway) and 1 (Subnet Mask) respectively.
Contact the network administrator for the proper settings for the network.
Note: The wireless handsets cannot "roam" across subnets, since the
wireless handsets cannot change their IP address while operational.
Ensure that all the APs are attached to the same subnet for proper
