Note

Failure to install the Device Package before the phone firmware upgrade may render the phones unusable.

- Features Available with Firmware Release

Features Available with Firmware Release

The following sections describe the features available with the Firmware Release.

- Call Admission Control

Call Admission Control

The Call Admission Control feature enables the user to hear a fast busy tone and see the message Not enough bandwidth on the phone LCD when the Cisco Unified Communications Manager rejects the call because of bandwidth or policy reasons.

If users see frequent Not enough bandwidth messages, the administrator may need to change the available bandwidth on the Cisco Unified Communications Manager.

Installation

Limitations and Restrictions

- Voice VLAN and IPv6 Limitation

- Phone Behavior During Times of Network Congestion

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 Click Here , 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.
