Features Available with the Firmware Release

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

Cisco Headset 531 and Cisco Headset 532

The Cisco Headset 531 and Cisco Headset 532 are two headsets developed for Cisco IP Phones and devices. Cisco Headset 531 features a single earpiece, and offers lightweight comfort. The Cisco Headset 532 features two earpieces for use in a noisy environment or busy office.

The Cisco Headset 531 and 532 can be used as standard headsets on Cisco IP Phone 8800 Series. You plug the headset into the headset port using the RJ connector.

The Cisco USB Adapter is also available for use with your Cisco headsets. Designed for phones with a USB port, the adapter pairs with your headset so you can customize your bass and treble, gain, and sidetone settings. It also lets you test your headset when you first plug it in to your phone. If you switch phones, then the adapter retains your settings so you don't have to configure them twice.

The adapter makes it easy to use basic, and advanced call features. Using the headset buttons, you can place a call, or answer an incoming call. A single tap also places an active call on hold. A quick double tap, and an incoming call is sent to your voicemail account. Press and hold for 2 seconds, and a call is ended.

The Cisco USB Adapter is supported on Cisco IP Phone 8851, 8851NR, 8861, 8865, and 8865NR.

Voice Feedback

The Cisco IP Phone 8800 Series now makes it easier for people with low vision or who are blind to connect with coworkers and customers.

When enabled, Voice Feedback alerts you to incoming calls by reading out the caller ID or phone number. You can Answer, Decline, or Ignore a call by pushing the corresponding softkey twice. Voice Feedback also guides you to your phone features by alerting you when you have selected a feature. Push a softkey once and a voice reads out the feature set up for that key. Push the softkey twice, and the feature is executed.

Voice Feedback will assist you as you navigate your phone settings and screens. As you move through your phone menu, it reads out the displayed screens, the settings chosen, and the status of your different parameters. Use this feature to customize your phone.

When your phone is idle, you can enable Voice Feedback by pushing the Select button on the Navigation ring three times. If you prefer, you can also enable it from the Accessibility screen on your phone.

Voice Feedback is only available for English language users. If this feature is not available to you, then it is grayed out on your phone.

Limitations and Restrictions

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect 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

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.

On-Hook Transfer Limitation in SIP Phones

When the Cisco Unified Communications Manager Transfer On-Hook Enabled field is enabled, users might report a problem with direct call transfer in SIP phones. If the user transfers the call and immediately goes on hook before they hear the ring signal, the call may drop instead of being transferred.

The user needs to hear the ring signal so that they can be sure that the call is being routed.

Ringtone Limitation During Firmware Downgrade from Release 11.5(1)

When the phone downgrades from Firmware Release 11.5(1) to Firmware Release 11.0(1), the phone may not ring when there is an incoming call. The ringtone for the line has been deleted and must be manually set in the Settings > Ringtone menu.

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.
