1. Primary TFTP: This is the
IP address of the TFTP server
that the phone will use by
default. If the TFTP address
is obtained through DHCP, it
will override this setting. If
DHCP is ON, the primary
TFTP is read only.
2. Alternate TFTP: This
allows you to configure an
alternate TFTP to use instead
of the primary server.
3. Use Primary/Use Alternate:
This selects which TFTP
server the phone will attempt
to obtain configuration from.
SIP 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:
1. Proxy IP
This is the IP address of the
proxy server.
2. Proxy Port
This is the SIP proxy server’s
port number. By default this
number is set to 5060.
3. Registrar IP
This is the IP address of the SIP
registrar.
4. Registrar Port
SIP registrar’s port number. By
default this is set to 5060.
5. Register
This enables and disables
registration of the IP phone with
the Registrar.
If YES is selected, the phone's IP
address is immediately registered
in the Registrar's database. If NO
is selected, the SIP phone's IP
address is immediately deleted
from the Registrar's database,
and the phone’s screen displays
"No Service".
6. User Name
This is used in the name field of
the SIP URI for the 480i phone
and for registering the 480i at the
registrar.
7. Display Name
This is 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
system.
8. Screen Name
This is used to display text on the
screen of the phone. You may
want to set this parameter to
display the phone user's name.
9. Auth Name
This is the authentication name
that is used in the username field
of the authorization header field.
This allows the phone to identify
itself to a proxy server that
requires authentication. When the
phone is challenged for
authorization, it will re-send the
challenged message with the
authentication name and
password.
10. Password
This is the authorization
password that is used to register
at the SIP registrar. When the
phone is challenged for
authorization, it will re-send the
challenged message with the
authentication name and
password
.
