A technician is trying to troubleshoot real-time call information from the CLI of a VCS. Which command should the technician enter?

The 'xstatus' command returns a static snapshot of current system state and does not provide continuous real-time updates as calls progress.

The 'xconfiguration' command is used to view or modify persistent configuration parameters, not to monitor live call activity.

The 'xfeedback register' command on the VCS CLI subscribes the session to real-time event notifications, delivering continuous updates as system state changes such as call establishment, registration events, and status transitions. Unlike xstatus, which provides a static point-in-time snapshot, xfeedback streams live data as events occur, making it the proper tool for real-time call troubleshooting. Administrators can target specific event paths to filter the feed to relevant call information.

The 'xhistory' command retrieves historical records of past events and sessions, not real-time call data.

The 'xcommand' namespace is used to invoke actions on the system such as dialing or disconnecting, not to display or monitor live call information.
