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 – the IP address of the time server. The time server controls the
date/time information that is displayed in standby mode.
Call Server IP – the IP address of the Avaya Communication Manager, such as the
DEFINITY MultiVantage system. 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 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
DHCP option 151, then a DNS lookup of "SLNKSVP2" if the DHCP options 6 (DNS
Server) and 15 (Domain Name) are configured.
OAI Server IP – the IP address of the NL OAI Gateway. If using static IP configuration,
this is simply the IP address of the NL OAI Gateway. If DHCP is being used, the
Wireless IP Telephone will try the DHCP option 152.
SSID
Enter the SSID.
Security
*NONE disables any 802.11 encryption or security authentication mechanisms.
For WEP, WPA-PSK and WPA2-PSK set each of the following options to match
exactly the settings in your APs.
