Figure 3-3 shows how one or more Unified IP IVR servers fit into an Unified CCE system.

Figure 3-3 A Unified Deployment Model within Unified CCE

Figure 3-4 also shows a Unified CCE deployment model, but focuses in on the Unified CM, Unified IP

IVR, and Unified CCE servers. In a Unified CCE system, there is the Unified CM server or servers, the

CRS server or servers, optional CRS subsystem servers such as MRCP ASR or MRCP TTS servers, and

the Unified CCE servers.

Note The optional MRCP ASR and TTS software cannot be on the same server as the CRS engine and is 3rd

party software, not Cisco software.

Unified IP IVR supports high availability failover between two CRS servers but not between a cluster of

servers. You can also deploy multiple CRS servers (with Unified IP IVR) and let Unified CCE manage

the load balancing and failover between them. If one of the IVRs fails, the Unified CCE system will

detect the failure, stop sending calls to the failed system, and instead send those calls to other Unified

IP IVRs.
