8/IP Phone User Guide
Using your 480i CT Base Station
Depending on how the phone has
been configured, the maximum
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
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, 5or 2, will appear on
the display. By using the r
and snavigation keys, you
can access the same functionality
as the Previous and Next
softkeys.
Softkeys as Customized
Speeddials
You can 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 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
indicator on the Supervisor’s
phone shows that the worker’s
phone is in use and busy.

/IP Phone User Guide 9
Using your 480i CT Base Station
On the 480i CT, the busy and idle
indicators show on the IP phone
screen display next to the softkey
programmed for BLF functionality.
When the monitored user is idle,
an icon with the handset on-hook
shows next to the BLF softkey.
When the monitored user is on an
active call, a small telephone icon
is shown with the handset off-
hook.
Note: You can also use the BLF
configured softkey to dial out.
Contact your system administra-
tor for more information.
Softkeys as Customized
BLF List
(For use with the BroadSoft
Broadworks Rel 13 or higher
platform only)
Your can set a softkey to BLF list.
The BLF list feature on the IP
phones is specifically designed to
support the BroadSoft Broadworks
Rel 13 Busy Lamp Field feature.
This feature allows the IP phone to
subscribe to a list of monitored
users defined through the
BroadWorks web portal.
In addition to monitoring the idle
and busy state, the BLF list feature
also supports the ringing state.
When the monitored user is idle,
there is a small telephone icon
shown with the handset on-hook.
When the monitored user is in
ringing state, there is a small bell
icon shown. When the monitored
user is on an active call then a
small telephone icon is shown with
the handset off-hook.
Note: The Broadworks BLF feature is
not the same as the Broadworks
Shared Call Appearance (SCA)
feature and does not permit call
control over the monitored
extension.
If you set a softkey to use BLF/List,
you must also enter a BLF List URI
at Operation->Softkeys and XML
->Services. The BLF List URI is the
name of the BLF list defined on the
BroadSoft BroadWorks Busy Lamp
field page for your particular user.
For example, my480i-blf-
[e-mail]. The value
of the BLF\List URI parameter
must match the list name
configured. Otherwise, no values
display on the 480i screen and the
feature is disabled.
Note: You can also use the BLF/List
configured softkey to dial out.
Example
A receptionist has a 480i CT
running Broadsoft firmware that
subscribes to a list of extensions
from the BroadWorks Application
Server. Each monitored extension
in the list shows up individually on
the 480i screen next to a softkey
button. The softkey icons on the
screen change depending on the
state of the extensions.
Softkeys for Accessing XML
Services
Extensible Markup Language
(XML) is a markup language much
like HTML. You system
administrator can create
customized XML menu services
and load them to your IP phone.
These services include things like
weather and traffic reports, contact
information, company info, stock
quotes, or custom call scripts.
Users can access XML applications
via the "Services" menu on the
480i CT or via a softkey set to use

10 /IP Phone User Guide
Using your 480i CT Base Station
XML services. The phone performs
an HTTP GET on the URI created
by your system administrator.
You can set the following
parameters for object requests:
• xml application URI
• xml application title
The xml application URI is the
application you are loading into
the IP phone. You must get this
URI from your system
administrator.
The xml application title is the
name of the XML application that
displays on the Services menu in
the IP Phone UI (as option #4).
Softkeys as Customized Flash
Key
You can set a softkey to generate a
flash event when it is pressed on
the 480i CT or 480i CT handset.
You do this by setting the softkey
to "flash". The IP phone generates
flash events only when a call is
connected and there is an active
RTP stream (for example, when the
call is not on hold).
Softkeys as Customized Park/
Pickup Keys
The IP phone (including the
480i CT handset) have a park and
pickup call feature that allows you
to park a call and pickup a call
when required. There are two ways
a user can configure this feature:
• Using a static configuration
• Using a programmable
configuration (configure soft-
keys)
Note: The IP phone accepts both meth-
ods of configuration. However, to
avoid redundancy, Aastra Tele-
com recommends you configure
either a static configuration or a
programmable configuration.
The IP phones support the Park/
Pickup feature on the Asterisk,
BroadWorks, Sylantro, and ININ
PBX servers.
Reference
For more information about
configuring park/pickup on the
480i CT phone, see "Park Calls/
Pick Up Parked Calls" on page 21.
Softkeys as Customized Empty
Key
You can set a softkey to force a
blank entry on the IP phone
display for a specific softkey. You
do this by setting the softkey to
"empty". The soft keys are added
in order (from softkey1 to
softkey20) after any hard-coded
keys have been added. If a
particular soft key is not defined, it
is ignored.

/IP Phone User Guide 11
Using your 480i CT Base Station
State-Based Softkeys
You can configure a specific state
to display when a softkey is being
used. Available states you can
configure for each softkey include:
•idle - The phone is not being
used.
•connected - The line currently
being displayed is in an active
call (or the call is on hold)
•incoming - The phone is ringing.
•outgoing - The user is dialing a
number, or the far-end is ring-
ing.
By default, the softkeys display in
the states of idle, connected,
incoming, and outgoing. All states
are enabled.
In the Aastra Web UI, the
operational states for each softkey
display enabled. To disable a state,
you uncheck the box for that
operational state.
The IP phone idle screen
condenses the softkeys. For
example, if you set softkey 12 as
the following:
Type: speedial
Label: Voicemail
Value *89
State: outgoing
then softkey 12 appears in
position 1 if no other softkeys are
set. A softkey type of "empty"
does not display on the idle screen
at all.
Connected State
The Connected State Screen will
appear when you are talking to
