You can change multiple extensions in the software from one extension to another, simultaneously.
Procedure
Enter change extension-station n, where n is the extension number that you want to change.
Caution:
The Change Station Extension screen does not change the emergency location extension that is administered within the system. You cannot use this screen to change an extension that is administered as an emergency location extension on either the Station screen or the IP Address Mapping screen.
In the TO EXTENSION fields:
Type a new extension that you want the current extension changed to.
Type a new extension for the message lamp extension.
Type a new extension for the emergency location ext. field
In the IP Parameter Emergency Location field, the system displays the words See IP-Network Map Form.
You can change the IP Parameter Emergency Location field only on the IP Address Mapping screen. Use the change ip-network-map command.
