on a phone. If your network requires it, however, you can manually configure information such as: an IP
address, TFTP server, and subnet information.
Cisco IP Phones can interact with other services and devices on your IP network to provide enhanced
functionality. For example, you can integrate Cisco Unified Communications Manager with the corporate
Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker
contact information directly from their IP phones. You can also use XML to enable users to access information
such as weather, stocks, quote of the day, and other web-based information.
Finally, because the Cisco IP Phone is a network device, you can obtain detailed status information from it
directly. This information can assist you with troubleshooting any problems users might encounter when using
their IP phones. You can also obtain statistics about an active call or firmware versions on the phone.
To function in the IP telephony network, the Cisco IP Phone must connect to a network device, such as a
Cisco Catalyst switch. You must also register the Cisco IP Phone with a Cisco Unified Communications
Manager system before sending and receiving calls.
