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. For information about enabling and configuring auto-registration, refer
to Cisco CallManager Administration Guide. Also, see the “Adding Phones to the

Cisco CallManager Database” section on page 2-5.

You must use Cisco CallManager to configure and assign telephony features tothe
Cisco IP Phones. See the “Telephony Features Available for the Phone” section

on page 5-2 for details.

Chapter 3 Setting Up the Cisco IP Phone

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 items such as call forwarding, speed dialing, and voice messaging
system options. See the “Adding Users to Cisco CallManager” section on

page 5-7 for details.

Network and Access Ports

The back of the Cisco IP Phone 7970 has a network port, labeled 10/100 SW, and
an access port, labeled 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.

Use the 10/100 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

Cisco IP Phone 7970” section on page 2-4 for details.

Use the 10/100 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.

Chapter 3 Setting Up the Cisco IP Phone

If you use external microphone or speakers, be sure to use devices that meet the
recommendations described in the “Using External Devices with Your Cisco IP

Phone” section on page 3-8.

To prevent users fromusing these external deviceswhenthe phone is using in-line
power,the ports (see Figure 3-1) have a sticker plug over them. You must remove
this sticker before using these external devices.

Additionally, the Cisco IP Phone 7970 has end-user configurable settings for
controlling the sound output to these external devices (Settings > User
Preferences > Audio Preferences). When the phone is using in-line power, the
sound settings for external devices are disabled. However, if the phone is using
external power, and you want to use external sound devices, be sure to help users
choose the appropriate settings. Details about these settings are included in the
Help available on the phone (via the ? button).

If the phone loses power, it will restart. If the external power supply is available
after the restart, the external devices remain available. If the external power
supply is unavailable and the phone switchesto in-line power,theexternal devices
are disabled, regardless of the current audio settings. When sufficient power is
provided by the external power supply, the phone will restart again and the
external devices will be available.
