Explanation
Cisco Collaboration System 12.x Solution Reference Network Designs (SRND): The call processing service of Unified CM does support the deployment of a single cluster's call processing nodes across an IP WAN as long as the total end-to-end round-trip time between the nodes does not exceed 80 ms and an appropriate quantity of QoS-enabled bandwidth is provisioned. The maximum one-way delay between any two Unified CM servers should not exceed 40 ms, or 80 ms round-trip time.
