Agent Greeting for Parent/Child is only supported for a very specific Parent/Child configuration. Agent Greeting in Parent/Child configurations must be approved by the Cisco Assessment to Quality (A2Q) process and require Cisco Design Mentoring Service to assure that the deployment model is designed and sized correctly to support the Agent Greeting feature.
After the call is delivered to the child system, the child router picks the target agent, the agent answers the call, and then CVP plays an agent greeting to both the caller and the agent. This feature is supported for both local agents and mobile agents.
On the child Unified CCE, you must:
Use IP-IVR on the child for call treatment, queuing and Whisper Announcement (if Whisper Announcement is enabled).
Use CVP on the child for Agent Greeting only; not for call queuing. You must use a separate VRU PG for the CVP. Translation route is used to send the greeting call to CVP.
