IP Settings
If you have a proxy server or have
a SIP registrar present at a
different location than the PBX
server, the following settings may
need to be changed:
• Proxy IP
IP address of the SIP proxy
server. Up to 64 alphanumeric
characters.
• Proxy Port
SIP proxy server’s port number.
Default is 0.
• Registrar IP

Up to 64 alphanumeric charac-
ters.
• Registrar Port
SIP registrar’s port number.
Default is 0.
• Register
Enables or disables the phone to
be registered with the Registrar.
When Register is disabled
globally, the phone is still active
and you can dial using user-
name and IP address of the
phone. A message "No Service"
displays on the idle screen and
the LED is steady ON. If Regis-
ter is disabled for a single line,
no messages display and LEDs
are OFF.

field
of the SIP URI for the IP phone
and for registering the phone at
the registrar. Valid values are up
to 20 alphanumeric characters.
• Display Name
Name used in the display name
field of the "From SIP" header
field. Some IP PBX systems use
this as the caller’s ID, and some
may overwrite this with the
string that is set at the PBX sys-
tem. Valid values are up to 20
alphanumeric characters.
• Screen Name
Name that displays on the idle
screen. Valid values are up to 20
alphanumeric characters.

ISTER request. Valid values are
up to 20 alphanumeric charac-
ters.

phone with the SIP proxy. Valid
values are up to 20 alphanu-
meric characters. Passwords are

isks when entering.
• NAT

settings are used to map your
firewall to an external NAT
device. You can enable or dis-
able NAT for a Nortel network,
or you can enter a specific NAT
IP address and NAT Port to use
(external IP address and hard-
coded port mapped on the NAT
device.).
• RTP Port Base
The Real-Time Transport Proto-
col port base configured for the
IP phone. Default is 3000.
Phone Status
The following options display
the network status, firmware
version, allow you to restart the
phone, and/or set the phone to the
factory defaults. The "Network
Status", "Firmware Version", and

available to the user and the
administrator and do not require a
password entry. The "Factory
Default" option is for
administrator use only.

the Ethernet port at the back of
the phone. Also displays the IP
