Configuring Telephony Features

---

After you install Cisco Unified IP Phones in your network, configure their network settings, and add them to Cisco Unified CallManager, you must use the Cisco Unified CallManager Administration application to configure telephony features.

This chapter provides an overview of these configuration and set-up procedures. Cisco Unified CallManager documentation provides detailed instructions for these procedures.

For suggestions about how to provide users with information about features, and what information to provide, see "Providing Information to Users Via a Website."

After you add Cisco Unified IP Phones to Cisco Unified CallManager, you can add functionality to the phones. Table 5-1 includes a list of supported telephony features, many of which you can configure using Cisco Unified CallManager Administration. The Reference column lists Cisco Unified CallManager documentation that contains configuration procedures and related information.

For more information about service parameters and the functions that they control, refer to Cisco Unified CallManager Administration Guide.
