When adding the phone, this error message appears:
Add failed. One of the required fields on the page has the same value as an entry that
already exists in the database. Please check the corresponding Find List page to verify
your entry does not exist.

(registered customers only)
Perform this workaround:
Create a new Phone Template in the Bulk Administration Tool (BAT),
then associate the previous Line Template. You can associate multiple Line
Templates if you need to delete more than one template.
Go back to the Phone Template page and click
Confirm the delete. BAT will remove both the Phone Templates and all
associated device templates.
