Error: Add failed

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.

Also, when trying to add the DN to the phone, this error appears:

Add failed. Cannot insert or update pattern. A Device Template exists with the same
pattern and partition.

This issue is documented by Cisco bug ID CSCtb03180 (registered customers only) .

Perform this workaround:

  1. 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.

  2. Go back to the Phone Template page and click Delete.

  3. Confirm the delete. BAT will remove both the Phone Templates and all associated device templates.
