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—he phones, the access gateways, and the resources necessary
for such features as call conferencing and route planning. Cisco CallManager also
provides authentication and encryption if configured for the telephony system.
For information about configuring Cisco CallManager to work with the IP devices
described in this chapter, refer to Cisco CallManager Administration Guide,
Cisco CallManager System Guide, and to Cisco IP Phone Authentication and
Encryption for Cisco CallManager 4.0(1.
