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 phones depend upon and interact with
several other key Cisco 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 Ph
