Configuring system-wide call appearance groups
These sections describe the system wide call appearance (SWCA) feature in detail:
• “Programming SWCA controls for your system” on page 471
• “How SWCA works in a call group” on page 474
• “Parking and retrieving calls on SWCA keys” on page 475
• “Call interactions with SWCA controls” on page 476
When you use the SWCA feature, your system gains extended flexibility in making and answering
calls between telephones within the system.
Note: Your telephone must have auto hold enabled if you want to use SWCA lines so that an
active call automatically gets placed on Hold if the user answers a second call. You must also
ensure that a Call Park code has been assigned (
“Understanding access codes” on page 320 ), and
that a Park timeout has been specified ( “Setting system timers” on page 479 ).
There are 16 SWCA codes that can be assigned to buttons when the telephone is being
programmed. Buttons are programmed under
Services, Telephony services, System DNs,
DN<group DN>, User preferences, Button programming . They can also be assigned by the
user at the telephone, using the button programming feature code ( FEATURE *3 ) and feature
codes FEATURE *521 to FEATURE *536 . Usually these buttons are programmed onto buttons
that have a display icon.
You can also assign non-appearing SWCA assignments. This particularly applies to the 7000 and
7100 digital phones, but can also apply to any telephone where you do not want to have SWCA
codes assigned to buttons with indicators. Refer to the SWCA call groups prompt explained in
“Setting SWCA call groups” on page 427 .
You also can assign SWCA codes to a Key Interface Module (KIM). Refer to “Programming
CAP/KIM buttons” on page 449 .
Finding SWCA calls
Telephones do not need to have SWCA buttons defined to retrieve or park SWCA calls. The
feature codes can be entered directly onto the handset to retrieve or park the calls. However, the
SWCA auxiliary codes described in this section only search codes assigned to the telephone that
invokes the feature.
These three feature codes allow you to navigate through the SWCA codes and current calls parked
on SWCA keys or SWCA assignments on a telephones.
FEATURE *520 searches for the next available SWCA code
.
If the system finds an available
code, the call is associated with the code and parked. If no code is available, the call remains active
on the current telephone, and unassigned to any SWCA button. If the call was already associated
with a SWCA code, the call is simply reparked on that code.
