This chapter discusses the concepts, provisioning, and configuration of Cisco Unified Communications
Manager (Unified CM) clusters when used in a Unified CCE deployment. Unified CM clusters provide
a mechanism for distributing call processing across a converged IP network infrastructure to support
Cisco Unified Communications, facilitate redundancy, and provide feature transparency and scalability.

This chapter covers only the Unified CCE operation with Unified CM clusters and proposes reference

clarify concepts relating to Unified CCE as an application supported by the Unified CM call processing
architecture. However, the foundational concepts are not duplicated here; become familiar with them
before continuing with this chapter.

This chapter documents general best practices and scalability considerations for sizing the Unified CM
servers used with your Unified CCE deployments. Within the context of this document, scalability refers
to Unified CM server and/or cluster capacity when used in a Unified CCE deployment. For information
on sizing and choosing a gateway, refer to the gateway information in the latest version of the Cisco
Unified Communications SRND, available at

Cluster Sizing Concepts
Before attempting to size a Unified CM cluster for a Unified CCE deployment, perform the following
design tasks:
design tasks:
•
Determine the different types of call flows.
•
Determine whether Unified CVP or IP IVR will be used for call treatment, self service, and
queueing.
queueing.
•
Determine the protocols to be used.
•
Determine redundancy requirements.
•
Determine all other customer requirements for Cisco Unified Communications that will share a
Unified CM cluster with a Unified CCE deployment (such as Cisco Unified IP Phones, applications
that are not part of Unified CCE, route patterns, and so forth).
