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

Basic Configuration Flow

Table 3-1 lists the general steps 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.
