DDITIONAL FEATURES SHARED CALL APPEARANCE (SCA) CALL BRIDGING
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/Button 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/image behavior in an SCA bridge call for users
involved in an SCA call (local) and users not involved in the SCA call (remote).
