Before You Begin Chapter 3 Installing the Cisco IP Phone Network Requirements For the Cisco IP Phone to successfully operate as a Cisco IP Phone endpoint in your network, your network must meet the following requirements: • Working VoIP Network - Voice over IP (VoIP) configured on your Cisco routers and gateways - Cisco CallManager Release 3.3 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 Cisco CallManager Configuration The Cisco IP Phone requires Cisco CallManager to handle call processing. Refer to the 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. See the "Using Auto-Registration" section on page 2-12 for details. You must use Cisco CallManager to configure and assign telephony features to the Cisco IP Phones. See the "Configuring Telephony Features Using Cisco CallManager Administration" section on page 5-2 for details. In Cisco CallManager, you can add users to the database and associate them with specific phones. By doing this, users gain access to web pages that allow them to configure phone options such as call forwarding and speed dialing. See the "Adding Users to Cisco CallManager" section on page 5-7 for details. Note If the Cisco IP Phone model that you want to configure does not appear in the Phone Type drop-down list in Cisco CallManager, go to the following URL and install the latest support patch for your version of Cisco CallManager: http://www.cisco.com/cgi-bin/tablebuild.pl/callmgr-33 Cisco IP Phone Administration Guide for Cisco CallManager 3.3, Cisco IP Phones 7902G/7905G/7912G 3-2 OL-6313-01
