SHARED CALL APPEARANCE (SCA) CALL BRIDGING
Shared Call Appearance (SCA) is when incoming calls are presented to multiple phones
simultaneously. For example, it is the ability to assign the boss' extension to a button on the
secretary's phone. Calls can be transferred between two phones with the same extension button
by simply putting the call on hold at one phone and picking it up on the other. Status LEDs light
and flash in unison, allowing all people sharing the extension to see the status at a glance.
The phones include an enhanced SCA for the call managers that support call bridging and
allows two or more SCA users to be connected in a call with a third party.
Refer to the following example.
Using the example above, when a call comes into Phone 1, Phone 2 and Phone 3 can pickup
the same call by pressing the SCA line key. Phone 2 and 3 display the call they are bridging
into on the LCD of the phones. Existing SCA parties in a bridge or one-to-one call hear an
audible beep when another party has joined the call.
If a phone is configured for SCA bridging and it attempts to join a call, but the account on the
server does not have this functionality enabled, an error message displays to the LCD on the
phone.
The SCA call bridging feature is disabled by default on all phones. Your Administrator can
enable/disable this feature if required. Contact your System Administrator for more information.
Note:
Your Administrator must enable/disable the beep on the server-side.
