The information displayed in the table depends on whether the extension has call appearances. For an extension without call appearances (e.g. T3, softphone, third party H.323 or analog), the table shows as many rows as there are currently calls, or a single row if the phone is idle. The following appears for a telephone with call appearances:

• Button Number – The number associated with the button on the telephone, if applicable.

• Button Type – Call, Line, Bridged or Cover Appearance button, if applicable.

• Call Ref – Call reference, assigned by the system and associated with the line in use. When a trace is in progress, any calls on the trunk will show (i) next to the Call Ref. If you select Call Details while a trace is in progress, the screen remains unchanged and a pop-up window appears which contains details about the selected call. The pop-up shows the state of the call at the time of selection and does not update. See Trace.

• Current State – The current state of the call associated with the button. See Call States (Extension).

• Time in State – Reset to zero each time there is a state change.

• Caller ID or Dialed Digits – The information displayed depends on the call direction.

  • Incoming Calls – The Caller ID name and number. System Status displays None if the system received no caller ID.
