Refer to the exhibit. An administrator is asked to allow new phones to use self-provisioning Interactive Voice Response. Which change to the Universal Device Template implements this feature?

The Idle URL configures a webpage displayed when the phone is idle, which is unrelated to self-provisioning IVR.

The Authentication Server URL is used for phone authentication, often with 802.1X, not directly for self-provisioning IVR.

Configuring the Secure Information URL in the Universal Device Template with the address of the self-provisioning IVR application enables this feature. When a new phone connects, it can then display a link or option that directs the user to this URL, allowing them to interact with the IVR system to provision their device with their user account.

The Directory URL points to the corporate directory service accessible from the phone, which allows contact searching but does not facilitate self-provisioning.
