Which action must an administrator take to provide a method that plays prerecorded messages when setting up a voicemail server in a Cisco collaboration on-premises system?

Cisco UCM does not manage voicemailboxes directly; it integrates with Unity Connection for voicemail services, and service voicemailboxes are not a standard Cisco UCM feature for playing prerecorded messages to callers.

Directory handlers are used for name lookups and routing callers based on directory information, not primarily for playing prerecorded messages as a general voicemail server function, which resides in Unity Connection.

In Cisco Unity Connection, call handlers are used to answer calls, play greetings, and provide options to callers, including playing prerecorded messages. A call handler template defines common settings for multiple call handlers, making it efficient to configure consistent behavior. Creating or modifying a call handler template and then applying it to a call handler is the correct method to implement prerecorded messages for incoming calls to the voicemail system.

"Telephony service" in Cisco Unity Connection is not the specific object used to configure and apply prerecorded messages for general call flow; call handlers and call handler templates are the correct mechanisms.
