Network Requirements

For the Cisco Unified IP Phones 7970G/7971G-GE to successfully operate as a Cisco Unified IP Phone endpoint in your network, your network must meet these requirements:

•Working Voice over IP (VoIP) Network:

–VoIP configured on your Cisco routers and gateways

–Cisco Unified CallManager Release 5.x 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

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

Cisco Unified CallManager Configuration

The Cisco Unified IP Phone requires Cisco Unified CallManager to handle call processing. Refer to Cisco Unified CallManager Administration Guide or context-sensitive help in the Cisco Unified CallManager application to ensure that Cisco Unified CallManager is set up properly to manage the phone and to properly route and process calls.
