Network Requirements
For the Cisco Unified IP Phone to successfully operate as a Cisco Unified IP Phone endpoint in your network,
your network must meet these requirements:
•
Working VoIP network:
◦
VoIP configured on your Cisco routers and gateways
◦
Cisco Unified Communications Manager 4.x and later 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 Unified IP Phone displays the date and time from Cisco Unified Communications Manager.
The time displayed on the phone can differ from the Cisco Unified Communications Manager time by up
to 10 seconds. The Cisco Unified Communications Manager server does not display the local time if it is
located in a different time zone than the phones.
Note
Cisco Unified Communications Manager Setup
The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call processing. See
Cisco Unified Communications Manager Administration Guide or to context-sensitive help in the
Cisco Unified Communications Manager application to ensure that Cisco Unified Communications Manager
is set up properly to manage the phone and to properly route and process calls.
If you plan to use autoregistration, verify that it is enabled and properly configured in Cisco Unified
Communications Manager before connecting any Cisco Unified IP Phone to the network. For information
about enabling and configuring autoregistration, see Cisco Unified Communications Manager Administration
Guide.
You must use Cisco Unified Communications Manager to configure and assign telephony features to the
Cisco Unified IP Phones.
In Cisco Unified Communications Manager, you can add users to the database and associate them with specific
phones. In this way, users gain access to web pages that allow them to configure items such as call forward,
speed dial, and voice message system options.
