Cisco Unified Communications Manager Deployment Models

Chapter Description

In this chapter from Implementing Cisco IP Telephony and Video, Part 1 (CIPTV1) Foundation Learning Guide (CCNP Collaboration Exam 300-070 CIPTV1), 3rd Edition, the author team introduces Cisco Unified Communications Manager (CUCM) and explores different redundancy models.

This chapter introduces the Cisco Unified Communications Manager (CUCM) deployment models and architectures that ensure redundancy and provide high availability for call processing and other services. The different redundancy models explored in this chapter can be applied to the different deployment models to provide fault tolerance for CUCM and its services.

Chapter Objectives

Upon completing this chapter, you will understand the CUCM deployment and redundancy options and be able to meet the following objectives:

  • Identify the supported CUCM deployment options.

  • Describe the characteristics of a CUCM single-site deployment, and identify the reasons for choosing this deployment option.

  • Describe the characteristics of a CUCM multisite deployment with centralized call processing, and identify the reasons for choosing this deployment option.

  • Describe the characteristics of a CUCM multisite deployment with distributed call processing, and identify the reasons for choosing this deployment option.

  • Describe the characteristics of a CUCM multisite deployment with clustering over the WAN, and identify the reasons for choosing this deployment option.

  • Describe the Cisco Collaboration Edge solution for teleworkers and remote workers

  • Explain how call-processing redundancy is provided in a CUCM cluster, and identify the requirements for different redundancy scenarios.
