Why each option
Media resources in Cisco Unified Communications Manager provide services such as audio announcements and music on hold, not call routing or codec negotiation functions.
An annunciator is a dedicated media resource that plays pre-recorded or text-to-speech audio announcements to callers, making it a direct CUCM media resource service.
Codec selection is performed by CUCM call processing logic during call setup negotiation, not by a media resource.
Dial peer selection is a routing function of IOS-based gateways and routers, not a service provided by CUCM media resources.
Voice activity detection is a codec-level feature configured on gateways or endpoints to suppress silence, not a service provided by a CUCM media resource.
Music on hold is a media resource that streams audio to callers placed on hold and is managed and allocated through the media resource group logic in CUCM.
