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:  
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  
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

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.

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].

Mounting the Phone to the Wall  
You can mount the Cisco Unified IP Phone on the wall using special brackets that are available in a  
Cisco Unified IP Phone wall mount kit. (Wall mount kits must be ordered separately from the phones.)  
You can also attach the phone to the will without a wall mount kit. In either case, you need the following  
tools and parts:  
Screwdriver  
Screws to secure the Cisco Unified IP Phone to the wall (included with the wall mount kit  
Before You Begin  
To ensure that the handset attaches securely to a wall-mounted phone, remove the handset wall hook  
from the handset rest, rotate the hook 180 degrees, and reinsert the hook. Turning the hook exposes a lip  
on which the handset catches when the phone is vertical. For an illustrated procedure, refer to Installing  
the Universal Wall Mount Kit for the Cisco Unified IP Phone at

Chapter 3 Setting Up the Cisco Unified IP Phone  
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.

The phone prompts for an authentication string.  
Enter the authentication code and press the Submit softkey.  
The phone begins to install, update, or remove the LSC, depending on how the CAPF was configured.  
During the procedure, a series of messages appears in the LSC option field in the Security Configuration  
menu so that you can monitor progress. When the procedure completes successfully, the phone will  
display Installed or Not Installed.  
The LSC install, update, or removal process can take a long time to complete. You can stop the process  
at any time by pressing the Stop softkey from the Security Configuration menu. (Settings must be  
unlocked before you can press this softkey.)  
When the phone successfully completes the installation procedure, it displays “Success.” If the phone  
displays, “Failure,” the authorization string may be incorrect or the phone may not enabled for  
upgrading. Refer to error messages generated by the CAPF and take appropriate actions.  
You can verify that an LSC is installed on the phone by pressing the Applications Menu button,  
choosing Settings > Model Information, and ensuring that the LSC setting shows Installed.
