Before You Begin

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

• Network Requirements, page 3-2

• Cisco Unified CallManager Configuration, page 3-2

• Safety, page 3-3

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

Chapter 3 Setting Up the Cisco Unified IP Phone

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.

Chapter 3 Setting Up the Cisco Unified IP Phone

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 5-16 for details.

Safety

Review the following warnings before installing the Cisco Unified IP Phone 7970. To see translations of these warnings, refer to the

Regulatory Compliance and Safety Information for the Cisco Unified IP Phone 7900 Series document that accompanied this device.

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning

To avoid electric shock, do not connect safety extra low voltage (SELV) circuits to telephone network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Caution Inline power circuits provide current over the cable. Use the Cisco provided cable

or a minimum 24 AWG communication cable.

The following warnings apply when you use an external power supply.

Caution Only use the proper Cisco approved external power supply. Reference the

installation manual provided with the phone.

Warning

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S. (240 VAC, 10 A international) is used on the phase conductors (all current-carrying conductors).

3-4

Warning

The device is designed to work with TN power systems.

The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.

Chapter 3 Setting Up the Cisco Unified IP Phone

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, page 3-5

• Handset, page 3-5

• Speakerphone, page 3-6

• Headset, page 3-6

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 on page 3-3 for more information.
