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.

Client Matter Code and Forced Authorization Code

You can configure the Cisco IP Conference Phone 8832 phone so that users must enter a billing code, or authorization code, or both codes after they dial a phone number. The billing code is called a Client Matter Code and is used for accounting or billing purposes. The authorization code, called a Forced Authorization Code, controls access to certain phone numbers.

When both a billing code and an authorization code are configured, users are first prompted for the authorization code and then the billing code.

You set up the access codes in the Cisco Unified Communications Manager. For more information, see the Administration Guide for Cisco Unified Communications Manager and IM and Presence Service.

Limitations and Restrictions

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect phone voice 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.
