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 components, including
Cisco Unified Communications Manager.
This chapter focuses on the interactions between the Cisco Unified IP Phone
7961G/7961G-GE and 7941G/7941G-GE and Cisco Unified Communications
