Before You Begin

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

Network Requirements

Cisco Unified CallManager Configuration

Safety

Network Requirements

For the Cisco Unified IP Phones 7970G/7971G-GE 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 CallManager Release 5.x or higher installed in your network and configured to handle call processing

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


Cisco Unified CallManager Configuration

The Cisco Unified IP Phone requires Cisco Unified CallManager to handle call processing. Refer to Cisco Unified CallManager Administration Guide or context-sensitive help in the Cisco Unified CallManager application to ensure that Cisco Unified 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 Unified CallManager before connecting any Cisco Unified IP Phone to the network. For information about enabling and configuring auto-registration, refer to Cisco Unified CallManager Administration Guide. Also, see the "Adding Phones to the Cisco Unified CallManager Database" section on page 2-13.

You must use Cisco Unified CallManager to configure and assign telephony features to the Cisco Unified IP Phones. See the "Telephony Features Available for the Phone" section on page 5-2 for details.

In Cisco Unified 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 items such as call forwarding, speed dialing, and voice messaging system options. See the "Adding Users to Cisco Unified CallManager" section on page 5-17 for details.

Understanding the Cisco Unified IP Phone 7970G/7971G-GE Components

The Cisco Unified IP Phone 7970G/7971G-GE includes these components on the phone or as accessories for the phone:

Network and Access Ports

Handset

Speakerphone

Headset

Network and Access Ports

The back of the Cisco Unified IP Phone 7970G/7971G-GE includes these ports:

Network port—Labeled 10/100 SW on the Cisco Unified IP Phone 7970G and 10/100/1000 SW on the Cisco Unified IP Phone 7971G-GE

Access port—Labeled 10/100 PC on the Cisco Unified IP Phone 7970G and 10/100/1000 PC on the Cisco Unified IP Phone 7971G-GE

Each port supports 10/100 or 10/100/1000 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 and 1000 Mbps connections.

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 2-4 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 a Cisco Unified IP Phone. It includes a light strip that indicates incoming calls and voice messages waiting.

Speakerphone

By default, the speakerphone is enabled on Cisco Unified IP Phones 7970G/7971G-GE.

You can disable the speakerphone through the Cisco Unified CallManager Administration application. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone Configuration web page for the phone, check the Disable Speakerphone check box.

Headset

Although Cisco Systems performs some 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. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco Unified 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 Unified IP Phone users.

Cisco Systems recommends the use of good quality 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 cell phones and two-way radios, some audio noise may still occur.

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 Unified 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-3). See the "Safety" section for more information.

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 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 Unified 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:

http://vxicorp.com/cisco

http://plantronics.com

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 through the Cisco Unified CallManager Administration application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified CallManager Administration, choose Device > Phone and locate the phone that you want to modify. In the Phone Configuration web page for the phone, check the Disable Speakerphone and Headset check box.

Using External Devices with Your Cisco Unified IP Phone

The following information applies when you use external devices with the Cisco Unified 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:

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 speakers, microphones, and headsets that are fully compliant with the EMC Directive [89/336/EC].

Installing the Cisco Unified IP Phone

You must connect the Cisco Unified IP Phone to the network and to a power source before using it. See Figure 3-1 for a graphical representation of the connections.


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



Note Before using external devices, read the "Using External Devices with Your Cisco Unified IP Phone" section for safety and performance information.

Figure 3-2 Connecting a Cable Lock to the Cisco Unified IP Phone 7970G/7971G-GE

Mounting the Phone to the Wall

You can mount the Cisco Unified IP Phone on the wall using the footstand as a mounting bracket or you can use special brackets available in a Cisco Unified IP Phone wall mount kit. (Wall mount kits must be ordered separately from the phones.) If you attach the phone to a wall using the standard footstand and not the wall mount kit, you need to supply the following tools and parts:

Screwdriver

Screws to secure the Cisco Unified IP phone to the wall

Use the following procedure to mount the phone on the wall using the standard footstand. See Figure 3-3 for a graphical overview of this procedure.

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, see Installing the Wall Mount Kit for the Cisco Unified IP Phone.


Caution Use care not to damage wires or pipes located inside the wall when securing screws to wall studs.

Procedure


Step 1 Push in the footstand adjustment button.

Step 2 Adjust the footstand so it is flat against the back of the phone.

Step 3 Insert two screws into a wall stud, matching them to the two screw holes on the back of the footstand.

Verifying the Phone Startup Process

After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by cycling through the following steps.

1. These buttons flash on and off in sequence:

Headset. (Only if the handset is off-hook when the phone powers up. In this case, hang up the handset within 3 seconds or the phone launches its secondary load instead of its primary load.)

Mute.

Speaker.

2. Some or all of the line keys flash orange.


Caution If the line keys flash red in sequence after flashing yellow, do not power down the phone until the sequence of red flashes completes. This sequence can take several minutes to complete.

3. Some or all of the line keys flash green.

Normally, this sequence takes just a few seconds. However, if the phone's Flash memory is erased or the phone load is corrupted, the sequence of green flashes will continue while the phone begins a software update procedure. If the phone performs this procedure, the following buttons light to indicate progress:

Headset—Phone is waiting for the network and completing CDP and DHCP configuration. (A DHCP server must be available in your network.)

Mute—Phone is downloading images from the TFTP server.

Speaker—Phone is writing images to its Flash memory.

4. The LCD screen displays the Cisco Systems, Inc., logo screen.

5. These messages appear as the phone starts:

Verifying load (if the phone load does not match the load on the TFTP server). If this message appears, the phone start up again and repeats step 1 through step 4 above.

Configuring IP.

Updating CTL.

Updating Locale.

Configuring CM List.

Registering.

6. The main LCD screen displays:

Current date and time

Primary directory number

Additional directory numbers and speed dial numbers, if configured

Softkeys

If the phone successfully passes through these stages, it has started up properly. If the phone does not start up properly, see the "Resolving Startup Problems" section on page 9-2.

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 mask

Default gateway IP address

TFTP server IP address

You may also configure these optional settings as necessary:

Domain name

DNS server IP address

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 CallManager 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 1-12. Also, refer to Cisco Unified CallManager Security Guide.

A Locally Significant Certificate (LSC) installs on phones after you perform the necessary tasks that are associated with the CAPF. You can use Cisco Unified CallManager Administration to configure an LSC, as described in Cisco Unified CallManager 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.

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 Begin

Make sure that the appropriate Cisco Unified CallManager 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 C:\Program Files\Cisco\Certificates folder in every server in the cluster.

The CAPF is running and configured.

Refer to Cisco Unified CallManager Security Guide for more information.


Note 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, perform the following steps.

Procedure


Step 1 Obtain the CAPF authentication string that was set when the CAPF was configured.

Step 2 From the phone, press the Settings > Security Configuration.
