IPv6 Address Released
Before IPv6 setup options can be configured on your device, IPv6 must be enabled and configured in Cisco
Unified Communication Administration. The following device configuration fields apply to IPv6 configuration:
• IP Addressing Mode
• IP Addressing Mode Preference for Signalling
If IPv6 is enabled in the Unified cluster, the default setting for IP addressing mode is IPv4 and IPv6. In this
addressing mode, the phone will acquire and use one IPv4 address and one IPv6 address. It can use the IPv4
and the IPv6 address as required for media. The phone uses either the IPv4 or IPv6 address for call control
signalling.
For more information about IPv6, see:
• "Common Device Configuration" in Cisco Unified Communications Manager Feature and Services
Guide, "IPv6 Support in Cisco Unified Communications Devices" chapter.
• IPv6 Deployment Guide for Cisco Collaboration Systems Release 12.0, located here:

TFTP Notes
When the phone looks for the TFTP server, the phone gives precedence to manually assigned TFTP servers,
regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes
the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and
IPv4 TFTP servers. The phone looks for the TFTP server in this order:
