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. Cisco 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 CallManager to work with the IP devices
described in this chapter, refer to Cisco CallManager Administration Guide and
Cisco CallManager System Guide.
Note If the Cisco IP Phone model that you want to configure does not appear in the
Phone Type drop-down list in Cisco CallManager, go to the following URL and
install the latest support patch for your version of Cisco CallManager:
