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 key on the secretary's phone. Calls can be transferred between two phones
with the same extension key 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 servers 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.
Phone A calls the SCA number and
all the phones in the SCA environment
ring.
Note: A user can place a call on hold while in an SCA bridged call, by pressing the SCA line key.
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.
Note:
Your Administrator must enable/disable the beep on the server-side.
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.
Keys States and LED Behavior
There are two call states on the phones that support SCA bridging:
•
Bridge-active - A bridged call is in progress
•
Bridge-held - The 3rd-party (i.e., non-SCA party) in the bridge is on hold.
The following tables provide the key states and LED behavior in an SCA bridge call for users involved in an SCA call and
users not involved in the SCA call.
