Note
Before You Begin
Before installing the Cisco IP Phone, review the requirements in these sections:
•
Network Requirements
For the Cisco IP Phone to successfully operate as a Cisco IP Phone endpoint in your network, your network must meet the following requirements:
•
–
–
•
Cisco CallManager Configuration
The Cisco IP Phone requires Cisco CallManager to handle call processing. Refer to Cisco CallManager Administration Guide or context-sensitive help in the Cisco CallManager application to ensure that Cisco CallManager 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 CallManager before connecting any Cisco IP Phone to the network. See the "Adding Phones to the Cisco CallManager Database" section for details.
You must use Cisco CallManager to configure and assign telephony features to the Cisco IP Phones. See the "Configuring Telephony Features Using Cisco CallManager" section for details.
In Cisco CallManager, you can add users to the database and associate them with specific phones. In this way, users gain access to web pages that allow them to configure phone items such as call forwarding, speed dialing, and voice messaging system options. See the "Adding Users to Cisco CallManager" section for details.
Network and Access Ports
The back of the Cisco IP Phones models 7960G and 7940G have two RJ-45 ports labelled 10/100 SW and 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 Mbps connections. On both the network port and access port, use full-duplex mode to avoid collisions.
Use the 10/100 SW port to connect the phone to the network. You must use a straight-through cable on these ports. The phone can also obtain inline power from the Cisco Catalyst switch over these connections. See the "Providing Power to the Cisco IP Phone" section for details.
Use the 10/100 PC 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 a Cisco IP Phone. It includes a light strip that indicates incoming calls and voice messages waiting.
Headset
Although Cisco Systems performs some internal testing of third-party headsets for use with the Cisco IP Phones, Cisco does not certify or support products from headset or handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco IP Phones are deployed, there is not a single "best" solution that is optimal for all environments. Cisco recommends that customers test the headsets that work best in their environment before deploying a large number of units in their network.
In some instances, the mechanics or electronics of various headsets can cause remote parties to hear an echo of their own voice when they speak to Cisco IP Phone users.
Cisco Systems recommends the use of good quality external devices, like headsets that are 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 cell phones and two-way radios, some audio noise may still occur. See the "Using External Devices with Your Cisco IP Phone" section for more information.
The primary reason that support of a headset would be inappropriate for an installation is the potential for an audible hum. This hum can either be heard by the remote party or by both the remote party and the Cisco IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, being near electric motors, large PC monitors. In some cases, a hum experienced by a user may be reduced or eliminated by using a local power cube (CP-PWR-CUBE-2). See the "Safety and Performance" section for more information.
Subjective to the User
Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound good to the user and the party on the far end. Sound is subjective and Cisco cannot guarantee the performance of any headsets or handsets, but some of the headsets and handsets on the sites listed below have been reported to perform well on Cisco IP Phones.
Nevertheless, it is ultimately still the customer's responsibility to test this equipment in their own environment to determine suitable performance.For information about headsets, see:
Connecting a Headset
To connect a headset to the Cisco 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 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 through the Cisco CallManager Administration application. If you do so, you also will disable the speakerphone.
To disable the headset on a Cisco IP Phone models 7960G and 7940G, choose Device > Phone from the Cisco CallManager Administration application, locate the phone you want to modify, and check the Disable Speakerphone and Headset check box.
Speakerphone
By default, the speakerphone is enabled on Cisco IP Phones. However, you can disable it on Cisco IP Phone models 7960G and 7940G.
To disable the speakerphone on these models, choose Device > Phone from the Cisco CallManager Administration application, locate the phone you want to modify, and check the Disable Speakerphone check box.
Safety and Performance
The following sections include important safety and performance information that you should review before you install and use your Cisco IP Phone:
•

Using External Devices with Your Cisco IP Phone
The following information applies when you use external devices with the Cisco IP Phone.
Cisco recommends the use of good quality external devices (speakers, microphones, and headsets) 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:
•
•
•
•
•
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
Installing the Cisco IP Phone
To install the Cisco IP Phone, perform the following steps. See Figure 3-1 for a graphical overview of these steps.
Step 1

Collect this information and see "Configuring Network Settings on the Cisco IP Phone."
Configuring Security on the Cisco IP Phone
The security features protects 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 CallManager server, and digitally sign files before they are delivered.
For more information about the security features, see the "Understanding Security Features for Cisco IP Phones" section. Also, refer to Cisco CallManager Security Guide.
The security features require that a locally significant certificate (LSC) be installed on the phone. You can use Cisco CallManager Administration to configure an LSC, as described in Cisco CallManager Security Guide.
Alternatively, you can configure an LSC on the phone by performing the following steps. This procedure will install an LSC, update an existing LSC, or remove an existing LSC, depending on how you have configured the CAPF.
Before You Begin
Make sure that the appropriate Cisco CallManager and the Certificate Authority Proxy Function (CAPF) security configurations are complete:
