Usage NotesPurposeNetwork Protocol
Phones use SRTP for media encryption.SRTP is an extension of the Real-Time
Protocol (RTP) Audio/Video Profile and
ensures the integrity of RTP and Real-Time
Control Protocol (RTCP) packets providing
authentication, integrity, and encryption of
media packets between two endpoints.
Secure Real-Time Transfer protocol
(SRTP)
Phones use TCP to connect to Cisco
Unified Communications Manager and to
access XML services.
TCP is a connection-oriented transport
protocol.
Transmission Control Protocol (TCP)
When security is implemented, phones use
the TLS protocol when securely registering
with the Cisco Unified Communications
Manager. For more information, see the
documentation for your particular Cisco
Unified Communications Manager release.
TLS is a standard protocol for securing and
authenticating communications.
Transport Layer Security (TLS)
TFTP requires a TFTP server in your
network, which can be automatically
identified from the DHCP server. If you
want a phone to use a TFTP server other
than the one specified by the DHCP server,
you must manually assign the IP address
of the TFTP server by using the Network
Setup menu on the phone.
For more information, see the
documentation for your particular Cisco
Unified Communications Manager release.
TFTP allows you to transfer files over the
network.
On the phone, TFTP enables you to obtain
a configuration file specific to the phone
type.

Cisco Unified Communications Manager Interaction
Cisco Unified Communications Manager is an open, industry-standard call processing system. Cisco Unified
Communications Manager software sets up and tears down calls between phones, integrating traditional PBX
functionality with the corporate IP network. Cisco Unified Communications Manager manages the components
of the IP telephony system, such as the phones, the access gateways, and the resources necessary for features
such as call conferencing and route planning. Cisco Unified Communications Manager also provides:
• Firmware for phones
• Certificate Trust List (CTL) and Identity Trust List (ITL) files using the TFTP and HTTP services
• Phone registration
• Call preservation, so that a media session continues if signaling is lost between the primary
Communications Manager and a phone
