Usage Notes
When security is implemented,
Cisco Unified IP Phones use the TLS
protocol when securely registering
with Cisco Unified Communications
Manager.
TFTP requires a TFTP server in your
network, which can be automatically
identified from the DHCP server. If
more than one TFTP server is
running in your network, you must
manually assign a TFTP server to
each phone locally.
Cisco Unified IP Phones receive and
process UDP messages.
