In a Cisco Unified Contact Center Enterprise deployment using the Multi-Site Centralized call processing model, all calls come into the central site for treatment or queuing and are then transferred across the WAN to agents. In this deployment, agents have reported that they are getting stuck in a reserved state but not getting the actual call delivered to them. What is the most likely cause of this failure?
A. There are not enough Cisco Unified IP IVR ports available to queue calls at the central site.
B. The agents have lost connection to the centralized CTI OS Servers.
C. The agent’s phone was off-hook during the transfer from the Cisco Unified IP IVR.
D. There was not enough bandwidth for the call over the WAN, and the Cisco Unified Communications Manager’s Locations-based Call Admission
Control rejected the call setup.
