Understanding the Cisco Unified IP Phone Components Chapter 3 Setting Up the Cisco Unified IP Phone • 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 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 to 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. For information about enabling and configuring auto-registration, refer to Cisco Unified Communications Manager Administration Guide. Also, see the Adding Phones to the Cisco Unified Communications Manager Database, page 2-11. You must use Cisco Unified Communications Manager to configure and assign telephony features to the Cisco Unified IP Phones. See Telephony Features Available for the Phone, page 5-1 for 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 items such as call forwarding, speed dialing, and voice messaging system options. See Adding Users to Cisco Unified Communications Manager, page 5-28 for details.

Each port supports 10/100 or 10/100/1000 Mbps half- or full-duplex connections to external devices. For the Cisco Unified IP Phone 7975G, 7971G-GE, and 7970G, 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 (the Cisco Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.5 3-2 OL-23092-01
