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)
