Configure BLF Presence
The BLF Presence feature allows a user (watcher) to monitor the real-time status of another user at a directory number or SIP URI from the device of the watcher. A watcher can monitor the status of the user by using the following options:
- BLF/SpeedDial buttons
- Missed call, placed call, or received call lists in the directories window
- Shared directories, such as the corporate directory
