Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and
transferring, redialing, speed dialing, conference calling, and voice messaging system access.
Cisco Unified IP phones also provide a variety of other features. For an overview of the telephony
features that the Cisco Unified IP Phone supports and for tips on configuring them, see the
Features Available for the Cisco Unified IP Phone" section on page
As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access
Cisco Unified CM and the rest of the IP network. By using DHCP, you have fewer settings to configure
on a phone, but if your network requires it, you can manually configure an IP address, TFTP server,
subnet information, and so on. For instructions on configuring the network settings on the Cisco Unified
IP Phones, see
Cisco Unified IP Phones can interact with other services and devices on your IP network to provide
enhanced functionality. For example, you can integrate Cisco Unified CM with the corporate
Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for
co-worker 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. For
information about configuring such services, see the
page 5-17
Finally, because the Cisco Unified 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. See
