Cisco Cisco IP Contact Center Release 4.6.1 Design Guide

A single-site deployment refers to any scenario where all voice gateways, agents, desktops, phones, and 
call processing servers (Unified CM, Unified ICM/Unified CCE, and Unified IP IVR or Cisco Unified 
Customer Voice Portal (Unified CVP)) are located at the same site and have no WAN connectivity 
between any Unified CCE software modules. 

 illustrates this type of deployment using the 

System Unified CCE model.

 shows a Unified IP IVR, a Unified CM cluster, redundant System Unified CCE servers, an 

Admin Controller (Administrative Workstation) and Historical Data Server (HDS), and a direct 
connection to the PSTN from the voice gateways. The System Unified CCE server in this scenario is 
running the following major software processes:

Call Router

Logger and Database Server

Unified CCE System PG with Unified CM Peripheral Interface Manager (PIM) and Unified IP IVR 
PIM

CTI Server

CTI Object Server (CTI OS)

Optionally, Cisco Agent Desktop (CAD) servers could be co-located on the System Unified CCE 
servers as well

Optionally the Central Controller and Agent Controller (Unified CCE System PG) could be split onto 
separate servers. For information on when to install the Unified ICM Central Controller and PG on 
separate servers, refer to the chapter on
