Cisco Cisco IP Contact Center Release 4.6.1 Design Guide

This section describes deployment models for the Unified Outbound Option.

Run Unified Outbound Option on a Windows server that meets the minimum requirements specified in 
the latest version of the Hardware and System Software Specification (Bill of Materials) for Cisco 
ICM/IPCC Enterprise & Hosted Editions, available at

 shows the installation of a single dialer. The Dialer is shown to be installed on side A of the 

duplexed PG; however, this is not a requirement. The single dialer configuration provides capacity for 
96 ports. This deployment model is used when scaling and high availability are not factors.

In a simplex Agent PG deployment, only one Dialer process is supported per Agent PG and Unified CM 
cluster.

For Cisco Unified Contact Center Enterprise deployments, the Unified Outbound Option Dialer and 
Media Routing PG processes run on the same physical server as the Agent PG. For System Unified CCE 
deployments, the Dialer and Media Routing PG processes run on a separate physical server from the 
Agent PG (see 

). In a two-dialer deployment on a duplex 

PG pair, the Media Routing PG will have two PIMs because each dialer gets its own Media Routing PIM.

The connection between the Dialer and the Unified CM cluster consists of multiple Skinny Client 
Control Protocol (SCCP) sessions, one for each dialer port. The duplexed PGs (Side A and Side B) 
shown in 

 are composed of a Generic PG (with Unified CCE PIM and a Unified IP IVR PIM), 

MR PG, CTI server, and CTIOS server process. The connection between the duplexed PG and the 
Unified CM cluster is the JTAPI link.
