An Overview of the
Cisco Unified IP Phone

The Cisco Unified SIP Phone 3911 provides voice communication over an
Internet Protocol (IP) network. The IP Phone functions like a digital business
telephone, allowing you to place and receive phone calls and to access features
such as mute, hold, transfer, speed dial, and call forward. The IP Phone also
supports security features that include image and digest authentication.

The Cisco Unified SIP Phone 3911 is interoperable with RFC-3261, RFC-3264,
RFC-3264, RFC-3311, RFC 3515, and RFC-3891.

An IP Phone, like other network devices, must be configured and managed. These
phones support G.711a, G.711u, G.729(decode only), and G.729a. This manual
describes the Cisco Unified SIP Phone 3911.

What Networking Protocols Are Used?

What Networking Protocols Are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking
protocols required for voice communication.

Tab le 1-1 provides an overview of

the networking protocols supported on the Cisco Unified SIP Phone 3911.

What Networking Protocols Are Used?

1-4

Cisco Unified SIP Phone 3911 Administration Guide for Cisco Unified Communications Manager

OL-14029-01

Ta b l e 1-1 Supported Networking Protocols on the Cisco Unified IP Phone

Networking Protocol Purpose Usage Notes

Cisco Discovery
Protocol (CDP)

CDP is a device-discovery protocol
that runs on all Cisco-manufactured
equipment.

Using CDP, a device can advertise its
existence to other devices and receive
information about other devices in
the network.

The Cisco Unified IP Phone uses
CDP to communicate information
such as auxiliary VLAN ID, per port
power management details, and
Quality of Service (QoS) configuration
information with the Cisco Catalyst
switch.

Dynamic Host
Configuration Protocol
(DHCP)

DHCP dynamically allocates and
assigns an IP address to network
devices.

DHCP enables you to connect an IP
phone into the network and have it
become operational without you
needing to manually assign an IP
address or configure additional
required network parameters.

DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and a TFTP server on
each phone locally.

Cisco recommends that you use
DHCP custom option 150. With this
method, you configure the TFTP
server IP address as the option value.
For additional supported DCHP
configurations, refer Cisco Unified

Communications Manager System
Guide.

Hypertext Transfer
Protocol (HTTP)

HTTP is the standard way of
transferring information and moving
documents across the Internet and the
web.

Cisco Unified SIP Phone 3911
supports HTTP.

1-5

Cisco Unified SIP Phone 3911 Administration Guide for Cisco Unified Communications Manager

OL-14029-01

Chapter 1 An Overview of the Cisco Unified IP Phone

What Networking Protocols Are Used?

Internet Protocol (IP) IP is a messaging protocol that

addresses and sends packets across
the network.

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.

Network Time Protocol
(NTP)

NTP is a protocol that is used to
synchronize timekeeping among a set
of distributed time servers and
clients.

When you configure Network Time
Protocol (NTP) on Cisco Unified
Communications Manager
Administration, the Cisco Unified IP
phones will get the date and time
from an NTP server.

Real-Time Transport
(RTP)

RTP is a standard protocol for
transporting real-time data, such as
interactive voice and video, over data
networks.

Cisco Unified IP Phones use the RTP
protocol to send and receive
real-time voice traffic from other
phones and gateways.

Session Description
Protocol (SDP)

SDP is the portion of the SIP protocol
that determines which parameters are
available during a connection
between two endpoints. Conferences
are established using only the SDP
capabilities that are supported by all
endpoints in the conference.

SDP capabilities, such as codec
types, DTMF detection, and comfort
noise are normally configured on a
global basis by the Cisco Unified
Communications Manager or the
Media Gateway in operation. Some
SIP endpoints may allow these
parameters to be configured on the
endpoint itself.

• Configuration Menus on the Cisco Unified IP Phone, page 4-3

Session Initiation
Protocol (SIP)

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.

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.

Transmission Control
Protocol (TCP)

TCP is a connection-oriented
transport protocol.

Trivial File Transfer
Protocol (TFTP)

TFTP allows you to transfer files
over the network.

On the Cisco Unified IP Phone,
TFTP enables you to obtain a
configuration file specific to the
phone type.

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 using the Network
Configuration menu on the phone.

User Datagram Protocol
(UDP)

UDP is a connectionless messaging
protocol for delivery of data packets.

Cisco Unified IP Phones transmit
and receive RTP streams, which
utilize UDP.

What Features are Supported on the Cisco Unified SIP Phone 3911?

What Features are Supported on the Cisco Unified
SIP Phone 3911?

The Cisco Unified SIP Phone 3911 functions much like digital business phones,
allowing you to place and receive telephone calls. In addition to traditional
telephony features, the Cisco Unified IP Phone includes features that enable you
to administer and monitor the phone as a network device.

This section covers the following topics:

• Feature Overview, page 1-7

• Configuring Telephony Features, page 1-8

• Configuring Network Parameters Using the Cisco Unified IP Phone, page 1-8

• Providing Users with Feature Information, page 1-9

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call
forwarding and transferring, redialing, speed dialing, and voice messaging system
access. Cisco

Unified IP phones also provide a variety of other features. For an

overview of the telephony features that the Cisco

Unified IP Phone supports and

for tips on configuring them, see the

“Telephony Features Available for the Cisco

Unified IP Phone” section on page 5-1.

As with other network devices, you must configure Cisco Unified SIP Phone 3911
so that it can access Cisco Unified Communications Manager and the rest of the
IP network. By using DHCP, you have fewer settings to configure on a phone, but
if your network requires it, you can manually configure an IP address, TFTP
server, and subnet mask. For instructions on configuring the network settings on
the Cisco

Unified IP Phones, see Chapter 4, “Configuring Settings on the Cisco

Unified IP Phone.”

Finally, because the Cisco Unified IP Phone is a network device, you can obtain
detailed status information from it directly. This information can assist you with
troubleshooting any problems users might encounter when using their IP phones.

Installing Cisco Unified IP Phones

After you have added the phones to the Cisco Unified Communications Manager
database, you can complete the phone installation. You (or the phone users) can
install the phone at the users’s location. The Cisco Unified IP Phone Installation
Guide that ships in the box with each phone provides directions for connecting the
phone handset, cables, and other accessories.

Note Before you install a phone, even if it is new, upgrade the phone to the current

firmware image. You can find the latest firmware for the Cisco Unified Phone
3911 at http://www.cisco.com/cgi-bin/tablebuild.pl/ip-3900ser.

After the phone is connected to the network, the phone startup process begins and
the phone registers with Cisco Unified Communications Manager. To finish
installing the phone, configure the network settings on the phone depending on
whether you enable or disable DHCP service.

If you used auto-registration, you need to update the specific configuration
information for the phone such as associating the phone with a user, changing the
button table, or directory number.
