IVX 128 Plus: additional features
10
6. UDP port
Enter the first two digits of the remote phone’s UDP port. This number is the base UDP port. The default
UDP base is 59. The last three digits will be the station’s extension number, and will be populated by
default. Extension 112, for example would have a UDP port of 59112 by default.
The UDP port for the remote phone does not have to be the same as for the IP PBX (as programmed in
Function 81). The UDP port for the remote phone must be one that the remote WAN gateway can
program as “open” and must not be already assigned to another device at the remote site. The remote
gateway will then have to be programmed to recognize that traffic destined for that UDP port should be
allowed to pass through its security system.
If the remote gateway cannot open UDP port 59xxx (where xxx is the phone’s extension), or if that port
is already open but designated for another device, the installer can choose any other base UDP number
between 10 and 65, inclusive. After entering the first two digits, the phone’s extension will populate
the last three digits.
7. Remote-access IP address
Enter the IP address that will be used for remote access to IVX 128 Plus. The display will default to the
IP address entered in Function 82 (see page
16
). If a Remote IP Feature Phone will use this address to
connect to IVX 128 Plus, press
#
to confirm; if a Remote IP Feature Phone will use an alternate IP
address to connect to IVX 128 Plus, enter that address and press
#
to confirm. “SAVE PARAMETERS?”
will appear on the display. If you have correctly entered the IP addressing parameters (items 1–7),
press
#
to program the parameters for any Remote IP Feature Phone; to abort programming, press
*
to
restore the system parameters to their previously set values.
8. Extension name
This is used for the LCD display, reports, and as a programming aid. The name’s length can be no
longer than 10 characters (See “Entering alphanumeric characters” in the Installation Manual).
Default:
The extension number.
9. CO line group
Assigns the extension’s ability to access one
or more
CO line groups (9, 8, and 71–76).
Default:
9.
10. and 11. Call forward busy/no answer
The extension can be set to call forward busy/no answer to another extension (or department), a
mailbox or a branch ID for day mode and differently for night mode.
Default:
The extension’s mailbox.
12. Extension page zone assignment
Remote IP phones cannot participate in any page zones.
