Privacy (more specifically, the Privacy Release button) allows a user to toggle between a call being “single user only” to “anyone can bridge in” and vice versa. The basic provisioning for the stations will control whether the call is by default private or publicly accessible.
An MCA bridged appearance is always private, and no other user can bridge in. Therefore, the Device Adapter provides this capability only with bridged and call appearances mapped as SCA. Further, as the analog set has no privacy release button, it will not support making or receiving private calls.
The 1210 UNIStim phones cannot bridge a call. Hence, Avaya recommends that you do not configure SCA on 1210 UNIStim phones. If SCA is configured on a 1210 UNIStim phone and if the SCA number is active, the user cannot use any other appearances on the 1210 phone to place a call or join another call. This limitation of the 1210 UNIStim phone is the same in both CS 1000 and Communication Manager.
CS 1000 endpoint user experience
By using the Single Call Arrangement functionality, any user sharing the SCA DN can bridge into the call by pressing the corresponding SCA DN key unless the user has invoked privacy or privacy was invoked by default.
A call is private by default. If the user presses the Privacy Release soft key, the call toggles into the non-exclusive mode and all DN appearances on all phones blink. Any user sharing the DN can press the DN button to join in. This turns the call into a conference. Only one user can bridge in for each Privacy Release key press.
Communication Manager endpoint user experience
The Exclusion feature is similar. It is activated in the following ways:
Manual Exclusion: Users turns the feature on or off by using the Exclusion button.
Automatic Exclusion: The feature is activated when a user makes a call. Users must manually deactivate it.
Buttonless Automatic Exclusion: The feature is activated when a user makes a call and deactivate when the call ends.
