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).
