Chapter 1 An Overview of the Cisco Unified IP Phone What Features are Supported on the Cisco Unified IP Phone 7962G and 7942G? Cisco Unified IP Phones do not support URLs with IPv6 addresses in the URL. This affects all IP Phone Service URLs, including services, directories, messages, help, and any restricted web services that require the phone to use the HTTP protocol to validate the credentials with the Authentication URL. If you configure Cisco Unified IP Phone services for Cisco 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 deploying IPv6 in your Cisco Unified Communications network, refer to Internet Protocol Version 6 (IPv6) in Cisco Unified Communications Manager Features and Services Guide and Deploying IPv6 in Unified Communications Networks with Cisco Unified Communications Manager 8.0.

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 Telephony Features Available for the Cisco Unified IP Phone, page 5-1. As 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. 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 Configuring Settings on the Cisco Unified IP Phone. Cisco Unified IP Phones can 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 OL-21011-01 Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.0 (SCCP and SIP) 1-9
