Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7960G and 7940G Components

For the Cisco Unified IP Phone to successfully operate as a Cisco Unified IP Phone endpoint in your network, your network must meet the following requirements:

•Working Voice over IP (VoIP) Network:

–VoIP configured on your Cisco routers and gateways

–Cisco Unified Communications Manager 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

The Cisco Unified IP Phone displays the date and time from Cisco Unified Communications Manager. If the Cisco Unified Communications Manager server is located in a different time zone than the phones, the phones will not display the correct local time.

Cisco Unified Communications Manager Configuration

The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call processing. Refer to Cisco Unified Communications Manager Administration Guide or context-sensitive help in the Cisco Unified Communications Manager application to ensure that

Cisco Unified Communications Manager 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 Communications Manager before connecting any Cisco Unified IP Phone to the network. See the “Adding Phones to the Cisco Unified Communications Manager Database” section on page 2-7for details.

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

In Cisco Unified Communications Manager, 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 Unified Communications Manager” section on page 5-12for details.
