The Cisco Unified IP Phones 7906G and 7911G function much like traditional
analog phones, allowing you to place and receive telephone calls. In addition to
traditional telephony features, each Cisco IP Phone includes features that enable
you to administer and monitor the phone as a network device.

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.
