Chapter 2      Deployment Models
IPT: Multi-Site with Distributed Call Processing
Unified CCE: Unified CCE System PG
The Unified CCE System PG is not a good fit for this model because it does not support Unified CVP 
for queuing, and the IVR PIMs on the Unified CCE System PG would go unused.
Unified CCE: Unified CCE PG
The Unified CCE PG is the recommended PG for this deployment model.
Unified CCE: Distributed Unified ICM Option with Distributed Call Processing 
Model
 illustrates this deployment model.

Advantages
The primary advantage of the distributed Unified ICM option is the redundancy gained from splitting the 
Unified ICM Central Controller between two redundant sites.
