Agents at remote locations must be registered to only one data center for their Cisco Unified IP

Cisco Unified Contact Center Enterprise IVR Peripheral Gateway cannot be split between the

E.
Cisco Unified Communications Manager Peripheral Gateways that are split between the two
data centers can share the same private network connection as the central controller (router and
