Cisco Unified Ip Phone Supported Features; Feature Overview - Cisco 7941G Administration Manual

Cisco Unified IP Phone
Cisco Unified IP Phones do not support URLs with IPv6 addresses in the URL. This affects all IP Phone
Service URLs, such as services, directories, messages, help, and any restricted web services that require the
phone to use the HTTP protocol to validate credentials with the Authentication URL. If you configure Cisco
Unified IP Phone services for Cisco Unified IP Phones, you must configure the phone and the servers that
support the phone service with IPv4 addresses.
If you configure IPv6 Only as the IP Addressing Mode for phones that are running SIP, the Cisco TFTP
service overrides the IP Addressing Mode configuration and uses IPv4 Only in the configuration file.
For more information on IPv6 deployment in your Cisco Unified Communications network, see the "Internet
Protocol Version 6 (IPv6)" chapter in the Cisco Unified Communications Manager Features and Services
Guide and Deploying IPv6 in Unified Communications Networks with Cisco Unified Communications Manager,
located at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/ipv6/ipv6srnd.html.

Cisco Unified IP Phone Supported Features

Cisco Unified IP Phones function much like a digital business phone, allowing you to place and receive phone
calls. In addition to traditional telephony features, the Cisco Unified IP Phones include features that enable
you to administer and monitor the phone as a network device.

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call forward, call transfer, redial,
speed dial, conference call, and voice message system access. Cisco Unified IP Phones also provide a variety
of other features.
With other network devices, you must configure Cisco Unified IP Phones to prepare them to access
Cisco Unified Communications Manager and the rest of the IP network. You can use DHCP to automatically
configure an IP address, TFTP server, and subnet information, or manually enter if required.
Cisco Unified IP Phones interact with other services and devices on your IP network to provide enhanced
functionality. For example, you can integrate the Cisco Unified IP Phones 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 Unified IP Phones are network devices, you can obtain detailed status information
from it directly. This information assists you with troubleshooting many problems users might encounter
when using their Cisco Unified IP Phones.
