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 IP 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 enironment
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.
