The currently-used IP address of the Call Server, the Call Server Port, and the

AVPP may be displayed in the phone settings menu of the standby menu in the
handset.
Phone IP – the IP Address of the Wireless IP Telephone. This is automatically assigned
if DHCP is used. If using Static IP configuration, you must obtain a unique IP Address
for each phone from your network administrator.
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 Wireless IP Telephone 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 your network administrator for the proper
settings for your network.
Note that the Wireless IP Telephones cannot "roam" across subnets, since they

cannot change their IP address while operational. Ensure that all your access
points are attached to the same subnet for proper operation. The Wireless IP
Telephone can change subnets if DHCP is enabled and the Wireless IP Telephone
is powered off then back on when within range of access points on the new
subnet.
TFTP Server IP – The IP address of a TFTP server on your network which holds software
images for updating the Wireless IP Telephones. 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 Wireless IP
Telephone 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 Wireless IP
Telephones in your network are kept up-to-date with the same version of software.
Syslog Server IP – the IP address of the syslog server. See the Diagnostics section for
more information.
Time Server IP – When using WPA2 Enterprise security, a time server must be
identified. Otherwise, this option is not used.
Call Server IP – the IP address of the Avaya Aura™ Communication Manager. If using
Static IP configuration, this is the IP address of the Communication Manager. If
DHCP is being used, the Wireless IP Telephone will try the following, in order – DHCP
Option 43 (Keyword MCIPADD), DHCP Option 176 (Keyword MCIPADD), and if DHCP
Option 6 (DNS Server) and Option 15 (Domain Name) are configured, DNS lookup of
server names found in the above options, and finally the DNS lookup of
"AvayaCallServer.DOMAIN".
Call Server Port – the IP port address of the Avaya Aura™ Communication Manager.
This port normally defaults to 1719, and is rarely changed. The port number entered
must be coordinated with the administration of the Communication Manager;
otherwise the wireless phone will not be able to register with the Communication
Manager. If DHCP is being used, this can be changed via DHCP Option 43 (Keywork
MCPORT) or DHCP Option 176 (Keyword MCPORT).
AVPP IP – the IP address of the Avaya Voice Priority Processor. Note that the Avaya
Voice Priority Processor must be statically configured to have a permanent IP address.
If DHCP is being used, the Wireless IP Telephone will try the following, in order: the
