# Importing contacts using Bulk User Provisioning

You can use Bulk User Provisioning to import contacts via the following methods:

- Active Directory
- CSV file
- Manually added using the Add button

Note: When a contact is created through BUP (using Manual Add), the Primary Phone, DID Number, External Number, and SIP Password fields are disabled, and the user cannot interact with these fields.

Conditions:

- The contacts imported via BUP are read-only for the users, that is, the contacts cannot be edited or deleted. Only the administrator can recreate the deleted contacts via BUP (Manual Add, CSV Import) and AD IDS Connection
- The contacts cannot be converted to a user.
