480i IP Phone User Guide 11
Using the 480i Phone
appearances that can be set up is 8
or 9 (4 line/call appearance as hard
keys and 4 or 5 as softkeys). If all
line/call appearances have been
set up for the same number,
a total of 9 lines can be configured.
If all line/call appearances have
been set up between two different
numbers, a total of 8 lines can be
configured. This means that when
all line/call appearances are in use,
1 call is connected while the rest
are on hold. No further outgoing or
incoming calls can be made until
one of the line/call appearances
becomes available.
In active states, such as ringing,
conference, connected, etc., all
softkeys disappear except softkeys
that have been set up as line/call
appearances, and any context
dependent softkeys required for
the active state, such as the Drop
softkey in the connected state.
Typically, context dependent
softkeys appear in the top left
position and all line/call
appearance softkeys appear in the
remaining positions.
Note: In some situations, such as
during a conference call, the line/
call appearance softkeys may
overwrite some of the context
dependent soft keys. In this
case, instead of the Previous
and Next softkeys, up or down
icons, 5 or 2, will appear on
the display. By using the r
and s navigation keys, you
can access the same functionality
as the Previous and Next
softkeys.
Softkeys as Customized
Speeddials
You can set custom softkeys as
speeddials on the 480i phone.
Speeddial softkeys can dial a star
code for a feature on the system or
a phone number or a set of digits.
A customized label displays inside
the phone’s display for each
softkey. If you press a custom
softkey, the phone goes off-hook
and dials the star code or the
number set up for this softkey.
Softkeys as Customized
"Do not Disturb"
You can set a softkey to perform
a"Do not Disturb" (DND) function.
If DND is set on a softkey, the key
switches DND ON and OFF. If the
phone shares a line with other
phones, only the phone that has
DND configured is affected.
The second line on the screen of
the IP phone shows when DND is
configured. When a call comes in
on the line, the caller hears a busy
signal or recorded message,
depending on the server
configuration.
Softkeys as Customized
Busy Lamp Field (BLF)
You can set a softkey to Busy Lamp
Field (BLF).
The BLF feature on the IP phones
allows a specific extension to be
monitored for state changes. BLF
monitors the status (busy or idle)
of extensions on the IP phone.
Note: The BLF setting is applicable to
the Asterisk server only.
Example
A Supervisor configures BLFs on
his phone for monitoring the status
of a worker’s phone use (busy or
idle). When the worker picks up
his phone to make a call, a busy
