   Note: Do not add an extension number in a Work Phone entry that contains a previously entered phone number. This action prevents Genesys Cloud from generating a dial plan for the user, and the extension does not appear in the list of extensions on the Assignments page. Add the extension number in an empty Work Phone entry.
8. Click Save.

If the extension number you want to remove exists within a range, you must delete the entire range of extensions. You cannot delete a single extension from a range unless it was originally entered as a single extension number. Also, you cannot delete an extension pool when an extension within the pool's range is assigned to a user.
