Explanation:
Incorrect answer: ACD

in distributed call processing deployments on a simple hub-and-spoke topology, you can implement
call admission control with a Cisco IOS gatekeeper. In this design, the call processing agent (which
could be a Unified CM cluster, Cisco Unified Communications Manager Express (Unified CME), or an
H)
323 gateway) registers with the Cisco IOS gatekeeper and queries it each time the agent wants to
place an IP WAN call.
