Removing Lines and Extensions from Service


Supervisors and attendants can remove problem lines and extensions from service. This helps ensure maximum system performance. For example, the attendant can busy-out a noisy line or problem extension until service personnel can repair the problem. The line or extension the appears busy to all callers. Following repair, the attendant or supervisor can return the line to service.

The extension or line removed from service shows as busy on the appropriate key (e.g., line key or Hotline key).
