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 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, the access gateways, and the resources necessary for such features as call conferencing and route planning. Cisco Unified CallManager also provides:

•Firmware for phones

•Authentication and encryption (if configured for the telephony system)

•Configuration file and CTL file, via TFTP service

•Phone registration

•Call preservation, so that a media session continues if signaling is lost between the primary CallManager and a phone)
