Click the Add New button.
From the Phone Type drop-down list, select the appropriate phone type or device, and click Next.

You can enable auto-registration in order to automatically add a Cisco Unified IP Phone to the Cisco Unified Communications Manager database when you connect the phone to your IP telephony network.

Use this section to troubleshoot your configuration.
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.
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 Delete.
Confirm the delete. BAT will remove both the Phone Templates and all associated device templates.
