With the introduction of Self-Provisioning IVR Service, the autoregistered IP phones on the Cisco Unified Communications Manager are assigned to users quickly with less effort. When you dial the CTI RP DN, that is configured on the Self-Provisioning page, from an extension of a user that uses the IVR service, the phone connects to the Self-Provisioning IVR application and prompts you to provide the Self-Service credentials. Based on the validation of the Self-Service credentials that you provide, the IVR service assigns the autoregistered IP phones to the users.
You can configure self-provisioning even if the service is deactivated, but the administrator cannot assign IP phones to users using the IVR service. By default, this service is deactivated.
To enable the Self-Provisioning IVR service, you must also enable the Cisco CTI Manager service.
For more information about how to configure self-provisioning, see the Cisco Unified Communications Manager Administration Guide.
