Understanding the Cisco Unified IP Phone 7931G Components

Headset

Although Cisco performs internal testing of third-party headsets for use with the Cisco Unified
IP Phones, Cisco does not certify or support products from headset or handset vendors.
Cisco recommends the use of good quality external devices, for example, headsets that are screened
against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of
headsets and their proximity to other devices such as mobile phones and two-way radios, some audio
noise or echo may still occur. An audible hum or buzz may be heard by either the remote party or by
both the remote party and the Cisco Unified IP Phone user. Humming or buzzing sounds can be caused
by a range of outside sources; for example, electric lights, electric motors, or PC monitors. For more
information, see
The Cisco Unified IP Phone 7931G supports wideband headsets.
Note
Note In some cases, hum may be reduced or eliminated by using a local power cube or power injector.
These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are
deployed means that there is not a single headset solution that is optimal for all environments.
Cisco recommends that customers test headsets in their intended environment to determine performance
before making a purchasing decision and deploying en mass.

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound
good to the user and to the party on the far end. Sound quality is subjective and Cisco cannot guarantee
the performance of any headsets. However, a variety of headsets from leading headset manufacturers
have been reported to perform well with Cisco Unified IP Phones. See manufacturer's sites for details.

Connecting a Headset

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the
phone. Press the Headset button on the phone to place and answer calls using the headset.
You can use the headset with all of the features on the Cisco Unified IP Phone, including the Volume
and Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the
headset microphone.

Disabling a Headset

You can disable the headset by using the Cisco Unified Communications Manager Administration. If
you do so, you also will disable the speakerphone.
To disable the headset from Cisco Unified Communications Manager Administration, choose Device >
Phone and locate the phone that you want to modify. In the Phone Configuration window for the phone,
check the Disable Speakerphone and Headset check box.
