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
