New and Changed Features

The following sections describe the features that are new or have changed in this release.


Note

Some features may require the installation of a Cisco Unified Communications Manager Device Package. Failure to install the Device Package before the phone firmware upgrade may render the phones unusable.

Features Available with the Firmware Release

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

Hunt Group Support for Conference Phones

You can configure conference phones into hunt groups in any supported Cisco Unified Communications Manager release.

Conference phone users can sign into and out of the hunt group. Users can also view the Call Queue.

Hunt Groups and Incoming Call Alerts Feature in Firmware Release 12.7(1)

You can configure your hunt groups to display either the hunt group name or hunt group number for incoming calls. This makes it easier for users to recognize and respond to group calls when logged into the queue.

By default, the pilot number displays for the incoming call. To have the group name display, enter a name in the Alerting Name field when you configure the pilot number.

This feature requires Cisco Unified Communications Manager 11.5(1)SU1 or later.

Installation

Installation Requirements

Before you install the firmware release, you must ensure that your Cisco Unified Communications Manager is running the latest device pack. After you install a device pack on the Cisco Unified Communications Manager servers in the cluster, reboot all the servers.


Warning

The Cisco IP Conference Phone 8832 PoE Injector is supported on phones running firmware release 12.0(1)SR2 and later. Confirm that the latest firmware release is installed on the Cisco Unified Communications Manager before you connect the Cisco IP Conference Phone 8832 with the PoE injector to the network.

If you are not using the latest firmware release, then your phone may downgrade to an earlier firmware release, and lose network connectivity.

Limitations and Restrictions

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect phone audio 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

Firmware Limitation of Cisco IP Conference Phone 8832 with Cisco IP Conference Phone 8832 PoE Injector

The Cisco IP Conference Phone 8832 PoE Injector is supported on phones running firmware release 12.0(1)SR2 and later. Confirm that the latest firmware release is installed on the Cisco Unified Communications Manager before you connect the Cisco IP Conference Phone 8832 with the PoE injector to the network.

If you are not using the latest firmware release, then your phone may downgrade to an earlier firmware release, and lose the network connectivity.

To recover a phone that has lost network connectivity, update Device Defaults for the Cisco IP Conference Phone 8832 to 8832-sip.12-0-1SR2-2.k3.cop.sgn or later in Cisco Unified Communications Manager Administration. Then, perform one of the following steps:

  • Force the phone to reboot from the alternate software image that supports the PoE Injector. To reboot your phone from the backup image, see Boot Up the Conference Phone from the Alternate Partition section in the Cisco IP Conference Phone 8832 Administration Guide for Cisco Unified Communications Manager.

  • Install and use the Cisco IP Conference Phone 8832 Ethernet Injector on the phone. This allows you to regain network connectivity. After the phone has upgraded to the latest firmware, you can again use the Cisco IP Conference Phone 8832 PoE Injector.

Health-Care Environment Use

This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.

Language Limitation

There is no localized Keyboard Alphanumeric Text Entry (KATE) support for the following Asian locales:

  • Chinese (China)

  • Chinese (Hong Kong)

  • Chinese (Taiwan)

  • Japanese (Japan)

  • Korean (Korea Republic)

The default English (United States) KATE is presented to the user instead.

For example, the phone screen will show text in Korean, but the 2 key on the keypad will display a b c 2 A B C.

Wireless Microphone Battery Limitation

When you press the Show detail softkey, the Cisco IP Conference Phone 8832 occasionally displays a false Bad battery warning. This issue occurs when you quickly reseat the wireless microphone 20 consecutive times or more.

To recover from this issue, perform the following steps in order:

  • Remove the microphone from the charging cradle.

  • Press the Mute button for approximately 10 seconds or until the microphone LED stops blinking white. Then, reseat the microphone on the charging cradle.

  • Restart the phone by disconnecting and reconnecting the Cisco IP Conference Phone 8832 Power Adapter.

    The Bad battery warning on the phone screen disappears and the current battery status appears. If you do not see the battery status, then the microphone battery has deteriorated and you must replace it.

Cisco Unified Communication Manager Public Keys

To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have "k3" in their name. To install a k3 cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the ciscocm.version3-keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error "The selected file is not valid" when you try to install the software package.

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 https://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 documentation for your particular Cisco Unified Communications Manager release.


Note

The latest Locale Installer may not be immediately available; continue to check the website for updates.

Cisco IP Phone Documentation Updates on Cisco Unified Communications Manager

The Cisco Unified Communications Manager Self Care Portal (Release 10.0 and later) and User Options web pages (Release 9.1 and earlier) provide links to the IP Phone user guides in PDF format. These user guides are stored on the Cisco Unified Communications Manager and are up to date when the Cisco Unified Communications Manager release is first made available to customers.

After a Cisco Unified Communications Manager release, subsequent updates to the user guides appear only on the Cisco website. The phone firmware release notes contain the applicable documentation URLs. In the web pages, updated documents display "Updated" beside the document link.


Note

The Cisco Unified Communications Manager Device Packages and the Unified Communications Manager Endpoints Locale Installer do not update the English user guides on the Cisco Unified Communications Manager.

You and your users should check the Cisco website for updated user guides and download the PDF files. You can also make the files available to your users on your company website.


Tip

You may want to bookmark the web pages for the phone models that are deployed in your company and send these URLs to your users.
