Phone Installation: Changing Extension Numbers
Procedure 2: Changing an Individual User's Extension Number
1. Select User .
2. Locate and select the relevant user.
3. On the User tab, change the Extension number to the required new number.
4. Click on another field. If an error warning appears it will most likely be due to a conflict with an existing use of that
extension number.
•
If this an error, click Cancel to return the user to their original extension number.
•
If this is intended as the other entry will be corrected click OK and then edit the other entry.
•
When OK is clicked, Manager will automatically propagate the number change to any hunt groups, incoming
call routes, user buttons, bridged appearance buttons and call coverage appearance buttons associated with
the user's original extension number.
5. If the user has an extension with which they are associated by being the extension's Base Extension setting, that
setting is not automatically updated. If the user should still be associated with that extension by default, the
extension must be updated manually to match the user's new extension number.
•
This part of the process requires an IP Office system reboot as it changes extension port settings.
6. Select Extension .
7. Change the Base Extension number to match the user extension who should now be associated with that
physical port by default.
8. Click OK . Manager will probably give a validation error message due to a user being associated with two
extensions. This can be ignored until all the user moves have been completed.
9. If changing several users repeat the process as required.
10.Click to revalidate the configuration and check that no conflicts between users and associated extensions.
11.If the configuration changes are complete, send the configuration back to the IP Office and select appropriate
settings for the reboot.
