Purpose
IP is a messaging protocol that
addresses and sends packets across
the network.
RTP is a standard protocol for
transporting real-time data, such as
interactive voice and video, over data
networks.
SRTP is available in addition to RTP.
SRTP adds security by encrypting
media streams during data transport.
SCCP includes a messaging set that
allows communications between call
control servers and endpoint clients
such as IP Phones. SCCP is
proprietary to Cisco Systems.
TCP is a connection-oriented
transport protocol.
TLS is a standard protocol for
securing and authenticating
communications.
Chapter 1
An Overview of the Cisco Unified IP Phone
Usage Notes
To communicate using IP, network
devices must have an assigned IP
address, subnet, and gateway.
IP addresses, subnets, and gateways
identifications are automatically
assigned if you are using the
Cisco Unified IP Phone with
Dynamic Host Configuration
Protocol (DHCP). If you are not
using DHCP, you must manually
assign these properties to each phone
locally.
Cisco Unified IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.
For SRTP to work, the phone or
phones being called must also
support SRTP or else those phones
cannot decrypt the secure media
stream.
Cisco Unified IP Phones use SCCP
for call control.
Cisco Unified IP Phones use TCP to
connect to
Cisco Unified CallManager and to
access XML services.
When security is implemented,
Cisco Unified IP Phones use the TLS
protocol when securely registering
with Cisco Unified CallManager.
