To function in the IP telephony network, the Cisco Unified IP Phone must be
connected to a networking device, such as a Cisco Catalyst switch. You must also
register the Cisco Unified IP Phone with a Cisco Unified CallManager system
before sending and receiving calls.

Understanding How the Cisco Unified IP Phone Interacts with
Cisco Unified CallManager
Cisco Unified CallManager is an open and industry-standard call processing
system. Cisco Unified CallManager software runs on a Windows 2000 or Linux
server and sets up and tears down calls between phones, integrating traditional
PBX functionality with the corporate IP network. Cisco Unified CallManager
manages the components of the IP telephony system—the phones, access
gateways, and the resources necessary for such features as call conferencing and
route planning.
For information about configuring Cisco Unified CallManager to work with the
IP devices described in this chapter, refer to Cisco Unified CallManager
Administration Guide and Cisco Unified CallManager System Guide.
