Chapter 3 Setting Up the Cisco Unified IP Phone
Before You Begin
Network Requirements
For the Cisco Unified IP Phone 7931G 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 Communications Manager Release 4.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 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 local time.
Cisco Unified Communications Manager Configuration
The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call
processing. To ensure that Cisco Unified Communications Manager is set up properly to manage the
phone and route and process calls, see the Cisco Unified Communications Manager Administration
Guide or the context-sensitive help in the Cisco Unified Communications Manager application.
If you plan to use auto-registration, verify that it is enabled and properly configured in
Cisco Unified Communications Manager Administration before connecting any Cisco Unified IP Phone
to the network. For information about enabling and configuring auto-registration, see the Cisco
Unified Communications Manager Administration Guide. Also, see Adding Phones to Cisco
Unified Communications Manager, page 2-7.
You must use Cisco Unified Communications Manager Administration to configure and assign
telephony features to the Cisco Unified IP Phones. For details, see Telephony Features Available for the
Phone, page 5-2.
In Cisco Unified Communications Manager Administration, you can add users to the database and
associate them with specific phones. In this way, users gain access to Cisco Unified CM User Option
Pages that allow them to configure items such as call forwarding, speed dialing, and voice messaging
system options. For details, see Adding Users to Cisco Unified Communications Manager, page 5-21.
