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
Voice over IP (VoIP) configured on your Cisco routers and gateways
Cisco Unified CallManager Release 5.0 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
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 Administration
application to ensure that Cisco Unified CallManager is set up properly to
manage the phone and to properly route and process calls.
Table 3-1 explains and provides references for many of the configuration
activities for which you use Cisco Unified CallManager Administration.
