Phone and Network Overview

Cisco Unified IP Phones enable you to communicate by using voice over a data network. To provide this
capability, the Cisco Unified IP Phones depend upon and interact with several other key Cisco Unified IP
Telephony components, including Cisco Unified Communications Manager.
This chapter focuses on the interactions between the Cisco Unified IP Phones and Cisco Unified
Communications Manager, DNS, DHCP, and TFTP servers, and switches. It also describes options for
powering phones.

Unified Communications Manager system before sending and receiving calls.
