Purpose
SIP is the IETF standard for
multimedia conferencing over IP. SIP
is an ASCII-based application-layer
control protocol (defined in RFC 3261)
that can be used to establish, maintain,
and terminate calls between two or
more endpoints.
TCP is a connection-oriented transport
protocol.
TLS is a standard protocol for securing
and authenticating communications.
TFTP allows you to transfer files over
the network.
On Cisco Cius, TFTP enables you to
obtain a configuration file specific to
Cisco Cius.
UDP is a connectionless messaging
protocol for delivery of data packets.
Overview of Cisco Cius
Usage notes
Like other VoIP protocols, SIP is
designed to address the functions of
signaling and session management
within a packet telephony network.
Signaling allows call information to be
carried across network boundaries.
Session management provides the ability
to control the attributes of an end-to-end
call.
Cisco Cius uses TCP to connect to Cisco
Unified Communications Manager and
to access XML services.
Cisco Cius uses the TLS protocol after
registering with Cisco Unified
Communications Manager securely.
TFTP requires a TFTP server in your
network, that can be automatically
identified from the DHCP server. If you
want Cisco Cius to use a TFTP server
other than the one specified by the
DHCP server, you must use the Network
Configuration menu on Cisco Cius to
assign the IP address of the TFTP server
manually.
For more information, see the Cisco
TFTP chapter in the Cisco Unified
Communications Manager System
Guide.
Cisco Cius transmits and receives RTP
streams, which utilize UDP.
