Network Requirements

For the Cisco IP Phone 7970 to successfully operate as a Cisco 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 CallManager Release 3.3(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

The Cisco IP Phone determines the date and time from Cisco CallManager.

Cisco CallManager Configuration

The Cisco IP Phone requires Cisco CallManager to handle call processing. Refer to Cisco CallManager Administration Guide or context-sensitivehelp 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 to the Cisco IP Phones. See the “Telephony Features Available for the Phone” section on page 5-2for details.
