Preparing to Install the Cisco Unified IP Phone on
Your Network
Cisco Unified IP Phones enable you to communicate using voice over a data network. To provide this
capability, the IP Phones depend upon and interact with several other key Cisco Unified IP Telephony
and network components, including Cisco Unified Communications Manager, DNS and DHCP servers,
TFTP servers, media resources, Cisco prestandard PoE, and so on.
This chapter focuses on the interactions between the Cisco Unified IP Phones 7975G, 7971G-GE,
7970G, 7965G, and 7945G and Cisco Unified Communications Manager, DNS and DHCP servers,
TFTP servers, and switches. It also describes options for powering phones.
