You can access information on the status of a specific extension by doing one of the following:

• Via a port that is associated with an analog or digital extension.
• By selecting an H.323 extension.
• By double-clicking Extensions and then selecting a specific extension from the navigation panel.
• By double-clicking an extension from the Extension Summary screen.

System Status uses the following method to indicate the port used by an analog or digital extension:

• If the extension is on the control unit, the designation is Control Unit followed by either Phone Port X (where X is the port number) or DS Port X (where X is the port number 1-8).
• If the extension is on an expansion module, the designation is Module XX (where XX is the port number 1-12) followed by Port X (where X is the port number 1-30).
