Setting Up the Cisco Unified IP Phone

This chapter includes the following topics, which help you install the Cisco Unified IP Phone 7931G on
an IP telephony network:

• Before You Begin, page 3-1

• Understanding the Cisco Unified IP Phone 7931G Components, page 3-2

• Installing the Cisco Unified IP Phone, page 3-5

• Securing the Phone with a Cable Lock, page 3-6

• Mounting the Phone to the Wall, page 3-7

• Verifying the Phone Startup Process, page 3-8

• Configuring Startup Network Settings, page 3-9

• Configuring Security on the Cisco Unified IP Phone, page 3-9

Note Before you install a Cisco Unified IP Phone, you must decide how to configure the phone in your

network. Then you can install the phone and verify its functionality. For more information, see

Chapter 2, “Preparing to Install the Cisco Unified IP Phone on Your Network.”

Before You Begin

Before installing the Cisco Unified IP Phone, review the requirements in these sections:

• Network Requirements, page 3-1

• Cisco Unified Communications Manager Configuration, page 3-2

Network Requirements

For the Cisco Unified IP Phone 7931G to successfully operate as a Cisco Unified IP Phone endpoint in
your network, your network must meet these requirements:

• Working Voice over IP (VoIP) network:

–

VoIP configured on your Cisco routers and gateways

–

Cisco Unified Communications Manager Release 4.x or higher installed in your network and
configured to handle call processing

Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7931G Components

• IP network that supports DHCP or manual assignment of IP address, gateway, and subnet mask

Note The Cisco Unified IP Phone displays the date and time from Cisco Unified Communications Manager.

If the Cisco Unified Communications Manager server is located in a different time zone than the phones,
the phones will not display the local time.

Cisco Unified Communications Manager Configuration

The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call
processing. Refer to Cisco Unified Communications Manager Administration Guide or to
context-sensitive help in the Cisco Unified Communications Manager application to ensure that
Cisco Unified Communications Manager is set up properly to manage the phone and to properly route
and process calls.

If you plan to use auto-registration, verify that it is enabled and properly configured in
Cisco Unified Communications Manager Administration before connecting any Cisco Unified IP Phone
to the network. For information about enabling and configuring auto-registration, refer to Cisco
Unified Communications Manager Administration Guide. Also, see the “Adding Phones to the Cisco

Unified Communications Manager Database” section on page 2-7.

You must use Cisco Unified Communications Manager Administration to configure and assign
telephony features to the Cisco Unified IP Phones. See the “Telephony Features Available for the Phone”

section on page 5-1 for details.

In Cisco Unified Communications Manager Administration, you can add users to the database and
associate them with specific phones. In this way, users gain access to Cisco Unified CM User Option
Pages that allow them to configure items such as call forwarding, speed dialing, and voice messaging
system options. See the “Adding Users to Cisco Unified Communications Manager” section on

page 5-18 for details.

Understanding the Cisco Unified IP Phone 7931G Components

The Cisco Unified IP Phone 7931G includes these components on the phone or as accessories for the
phone:

• Network and Access Ports, page 3-2

• Handset, page 3-3

• Speakerphone, page 3-3

• Headset, page 3-3

Network and Access Ports

3-2

The back of the Cisco Unified IP Phone includes these ports:

• Network port—Labeled 10/100 SW

• Access port—Labeled 10/100 PC

Each port supports 10/100 Mbps half- or full-duplex connections to external devices. You can use either
Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 connections.

Chapter 3 Setting Up the Cisco Unified IP Phone

Use the SW network port to connect the phone to the network. You must use a straight-through cable on
this port. The phone can also obtain inline power from a switch over this connection. See the “Providing

Power to the Phone” section on page 2-3 for details.

Use the PC access port to connect a network device, such as a computer, to the phone. You must use a
straight-through cable on this port.

Handset

The handset is designed especially for use with the Cisco Unified IP Phone 7931G. It includes a light
strip that indicates incoming calls and voice messages waiting.

To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port
on the back of the phone.

Note The handset does not support wideband audio.

Understanding the Cisco Unified IP Phone 7931G Components

Speakerphone

Headset

Note The Cisco Unified IP Phone 7931G supports wideband headsets.

By default, the speakerphone is enabled on the Cisco Unified IP Phone 7931G.

You can disable the speakerphone by using the Cisco Unified Communications Manager Administration.
To do so, choose Device > Phone and locate the phone you want to modify. In the Phone Configuration
window for the phone, check the Disable Speakerphone check box.

Although Cisco performs internal testing of third-party headsets for use with the Cisco Unified IP
Phones, Cisco does not certify or support products from headset or handset vendors.

Cisco recommends the use of good quality external devices, for example, headsets that are screened
against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of
headsets and their proximity to other devices such as mobile phones and two-way radios, some audio
noise or echo may still occur. An audible hum or buzz may be heard by either the remote party or by both
the remote party and the Cisco Unified IP Phone user. Humming or buzzing sounds can be caused by a
range of outside sources; for example, electric lights, electric motors, or PC monitors. See Using

External Devices, page 3-4 for more information.

OL-18988-01

Note In some cases, hum may be reduced or eliminated by using a local power cube or power injector.

These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are
deployed means that there is not a single headset solution that is optimal for all environments.

Cisco recommends that customers test headsets in their intended environment to determine performance
before making a purchasing decision and deploying en mass.
