Before You Begin

Before installing the CiscoUnified IP Phone, review the requirements in these

sections:

•Network Requirements, page 3-2

•Cisco UnifiedCallManager Configuration, page 3-2

•Safety, page3-3

For the CiscoUnified 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 UnifiedCallManager 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.

The Cisco UnifiedIP Phone requires Cisco Unified CallManager to handle call

processing. Refer to Cisco Unified CallManager Administration Guide or

context-sensitive help in the CiscoUnified CallManager application to ensure

that Cisco Unified CallManager is set up properly to manage the phone and to

properly route and process calls.
