Chapter 3 Setting Up the Cisco Unified IP Phone
Understanding the Cisco Unified IP Phone 7931G Components
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.
Speakerphone
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.
Headset
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.
Note
Note
The Cisco Unified IP Phone 7931G supports wideband headsets.
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.

Chapter 3 Setting Up the Cisco Unified IP Phone
Understanding the Cisco Unified IP Phone 7931G Components
Audio Quality Subjective to the User
Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound
good to the user and to the party on the far end. Sound quality is subjective and Cisco cannot guarantee
the performance of any headsets. However, a variety of headsets from leading headset manufacturers
have been reported to perform well with Cisco Unified IP Phones. See manufacturer’s sites for details.
Connecting a Headset
To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the
phone. Press the Headset button on the phone to place and answer calls using the headset.
You can use the headset with all of the features on the Cisco Unified IP Phone, including the Volume and
Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the
headset microphone.
Disabling a Headset
You can disable the headset by using the Cisco Unified Communications Manager Administration. If you
do so, you also will disable the speakerphone.
To disable the headset from Cisco Unified Communications Manager Administration, choose Device >
Phone and locate the phone that you want to modify. In the Phone Configuration window for the phone,
check the Disable Speakerphone and Headset check box.
Using External Devices
The following information applies when you use external devices with the Cisco Unified IP Phone:
Cisco recommends the use of good quality external devices that are shielded (screened) against
unwanted radio frequency (RF) and audio frequency (AF) signals.
Depending on the quality of these devices and their proximity to other devices such as mobile phones or
two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one
or more of the following actions:
•
•
•
•
•
Move the external device away from the source of the RF or AF signals.
Route the external device cables away from the source of the RF or AF signals.
Use shielded cables for the external device, or use cables with a better shield and connector.
Shorten the length of the external device cable.
Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of
external devices, cables, and connectors. The system will perform adequately when suitable devices are
attached using good quality cables and connectors.
Caution
In European Union countries, use only external headsets that are fully compliant with the EMC Directive
[89/336/EC].

Configuring Startup Network Settings
Configuring Startup Network Settings
If you are not using DHCP in your network, you must configure these network settings on the
Cisco Unified IP Phone after installing the phone on the network:
•
•
•
•
IP address
IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)
Default gateway IP address
TFTP server IP address
You also may configure the domain name and the DNS server settings, if necessary.
Collect this information and see the instructions in Chapter 4, “Configuring Settings on the Cisco
Unified IP Phone.”
Configuring Security on the Cisco Unified IP Phone
The security features protect against several threats, including threats to the identity of the phone and to
data. These features establish and maintain authenticated communication streams between the phone and
the Cisco Unified Communications Manager server, and digitally sign files before they are delivered.
For more information about the security features, see the “Understanding Security Features for Cisco
Unified IP Phones” section on page 1-11. Also, refer to Cisco Unified Communications Manager
Security Guide.
A Locally Significant Certificate (LSC) installs on phones after you perform the necessary tasks that are
associated with the Certificate Authority Proxy Function (CAPF). You can use
Cisco Unified Communications Manager Administration to configure an LSC, as described in
Cisco Unified Communications Manager Security Guide.
Alternatively, you can initiate the installation of an LSC from the Security Configuration menu on the
phone. This menu also lets you update or remove an LSC.
Before you do so, make sure that the appropriate Cisco Unified Communications Manager and the
Certificate Authority Proxy Function (CAPF) security configurations are complete:
•
•
The CTL file should have a CAPF certificate.
The CAPF certificate must exist in the /usr/local/cm/.security/certs folder in every server in the
cluster.
•
The CAPF is running and configured.
Refer to Cisco Unified Communications Manager Security Guide for more information.
Depending on how you have configured the CAPF, this procedure installs an LSC, updates an existing
LSC, or removes an existing LSC.
To configure an LSC on the phone, follow these steps:
Procedure
Step 1
Step 2
Obtain the CAPF authentication code that was set when the CAPF was configured.
From the phone, press the Applications Menu button, then choose Settings > Security Configuration.
