Cisco Cisco Computer Telephony Integration OS 8.5 Release Notes

Customer application’s resource usage

It is important to ensure that CPU usage does not regularly exceed 50% during 
normal operation when the system fully loaded. Since performance is affected by 
many factors including CPU capacity, it is important to monitor your system to 
determine the maximum number of agents you can support without exceeding the 
50% CPU usage limit.

If you are planning to implement an integration such as this, it is highly 
recommended that you perform laboratory testing with your application under 
conditions similar to those you expect to deploy under. Also, applications of this 
type should receive Skillgroup statistics via a separate monitor mode session 
rather than through each AgentMode session in order to reduce bandwidth and 
message processing. Please consult the CTI OS Developer’s Guide section on 
“How to Set Up a Monitor-Mode Application to Receive Skill Group Statistics”.   
It is also expected that the system running the customer application in this 
scenario will be on a server caliber system that at least meets the recommended 
hardware requirements in the Cisco IPCC PG BOM requirements.

 outlines the results of the basic testing that was performed. This is 

provided as informational only and is not intended to guarantee that you will 
achieve the same results.These tests were performed on a client system with the 
following specifications:

CPU:  2.6 GHz Intel Pentium 4

 

MEM:  1024 MB

OS:  Windows 2000 Server, SP 2

Skill Groups per Agent: 2 SkillGroups, no statistics.

Note that these tests were performed on a client system that does not meet the 
recommended hardware requirements specified in the Bill of Materials for Cisco 
Enterprise Contact Routing document at
