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 Cisco Unified IP Phones depend upon and
interact with several other key Cisco Unified IP Telephony and network
components.
This chapter focuses on the interactions between the Cisco Unified IP Phone
7960G and 7940G and Cisco Unified CallManager, DNS and DHCP servers,
TFTP servers, and switches. It als
