Understanding How the Cisco IP Phone Interacts with Cisco CallManager

Cisco CallManager is an open and industry-standard call processing system.

Cisco CallManager software runs on a Windows 2000 server and sets up and tears

down calls between phones, integrating traditional PBX functionality with the

corporate IP network. CiscoCallManager 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 CiscoCallManager to work with the IP devices

described in this chapter, refer to CiscoCallManager Administration Guide and

Cisco CallManager System Guide.
