Depending upon how the phone
has been configured, the maxi-
mum number of total line/call
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 num-
bers, a total of 8 lines can be con-
figured. 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 will 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 will appear
in the top left position and all line/
call appearance softkeys will
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

s
and navigation keys, you
can access the same functionality
as the Previous and Next
softkeys.

Speeddials
Your system administrator may
also have set up custom softkeys as
speeddials. 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 will go
off-hook and dial the star code or
the number set up for this softkey.

"Do not Disturb"
Your system administrator can set
a softkey to "Do not Disturb"
(DND).
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.

Busy Lamp Field (BLF)
Your system administrator 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
