Usage NotesPurposeNetwork Protocol
To communicate with 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 phone with Dynamic
Host Configuration Protocol (DHCP). If
you are not using DHCP, you must
manually assign these properties to each
phone locally.
The phones support IPv6 address. For more
information, see the documentation for your
particular Cisco Unified Communications
Manager release.
IP is a messaging protocol that addresses
and sends packets across the network.
Internet Protocol (IP)
The phone supports LLDP on the PC port.LLDP is a standardized network discovery
protocol (similar to CDP) that is supported
on some Cisco and third-party devices.
Link Layer Discovery Protocol (LLDP)
The phone supports LLDP-MED on the SW
port to communicate information such as:
• Voice VLAN configuration
• Device discovery
• Power management
• Inventory management
For more information about LLDP-MED
support, see the LLDP-MED and Cisco
Discovery Protocol white paper at this
URL:
https://www.cisco.com/en/US/tech/tk652/tk701/technologies_white_paper0900aecd804cd46d.shtml
LLDP-MED is an extension of the LLDP
standard developed for voice products.
Link Layer Discovery Protocol-Media
Endpoint Devices (LLDP-MED)
Phones use the RTP protocol to send and
receive real-time voice traffic from other
phones and gateways.
RTP is a standard protocol for transporting
real-time data, such as interactive voice and
video, over data networks.
Real-Time Transport Protocol (RTP)
RTCP is enabled by default.RTCP works in conjunction with RTP to
provide QoS data (such as jitter, latency,
and round-trip delay) on RTP streams.
Real-Time Control Protocol (RTCP)
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.
SIP is the Internet Engineering Task Force
(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.
Session Initiation Protocol (SIP)
