Limitations and Restrictions
Voice VLAN and IPv6 Limitation
If the PC attached to the PC port of the phone is using IPv6, we recommend that the PC Voice LAN access be disabled. This ensures that the PC can connect to the Voice VLAN.
Phone Behavior During Times of Network Congestion
Anything that degrades network performance can affect Cisco IP Phone voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
Administrative tasks, such as an internal port scan or security scan
Attacks that occur on your network, such as a Denial of Service attack
To reduce or eliminate any adverse effects to the phones, schedule administrative network tasks during a time when the phones are not being used or exclude the phones from testing.
Unified Communications Manager Endpoints Locale Installer
By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.
To access the Locale Installer required for a release, access http://software.cisco.com/download/navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.
For more information, see the "Locale Installer" section in the Cisco Unified Communications Operating System Administration Guide.
Note | The latest Locale Installer may not be immediately available; continue to check the website for updates. |
