System Configuration Overview

For best results when configuring a complete Cisco Unified Communications system, start with the system-level components and work toward the individual devices.

This chapter presents an overall flow, or order, for configuring the components of your Cisco Unified Communications network. It covers the following topics:

Table 3-1 lists the general steps that are involved in configuring a complete IP telephony system. If you are not using a particular feature or component, you can skip that step. You have some flexibility in the order for performing these configuration steps, and in some cases, you might have to alternate between steps or return to a given step several times to complete your configuration.
