Sizing Considerations for Unified CCE
For the most current hardware specifications for WebView and HDS servers, refer to the latest version 
of the Hardware & System Software Specification (Bill of Materials) for Cisco ICM/IPCC Enterprise &

Additional Sizing Factors
Many variables in the Unified CCE configuration and deployment options can affect the hardware 
requirements and capacities. This section describes the major sizing variables and how they affect the 
capacity of the various Unified CCE components. In addition, 
 summarizes the sizing 
variables and their effects.
Busy Hour Call Attempts (BHCA)
The number of calls attempted during a busy hour is an important metric. As BHCA increases, there is 
an increase in the load on all Unified CCE components, most notably on Unified CM, Unified IP IVR, 
and the Unified CM PG. The capacity numbers for agents assume up to 30 calls per hour per agent. If a 
deployment requires more than 30 calls per hour per agent, it will decrease the maximum number of 
supported agents for the agent PG and should be handled on a case-by-case basis.
Agents
The number of agents is another important metric that will impact the performance of most Unified CCE 
server components, including Unified CM clusters. For the impact of agents on the performance of 
Unified CM components, see 
Average Skill Groups per Agent
The number of skill groups per agent (which is independent of the total number of skills per system) has 
significant effects on the CTI OS Server, the Agent PG, and the Unified ICM Router and Logger. Cisco 
recommends that you limit the number of skill groups per agent to 5 or fewer, when possible, and that 
you periodically remove unused skill groups so that they do not affect system performance. You can also 
manage the effects on the CTI OS server by increasing the value for the frequency of statistical updates. 
 shows examples of how the number of skill groups per agent can affect the capacity of the 
Unified CCE system. The numbers in 
 are based on the information listed in the section on 
, and it shows capacity per CTI OS instance.
