Headset

Although Cisco performs internal tests of third-party headsets for use with the Cisco Unified IP Phones, Cisco

does not certify or support products from headset or handset vendors.

We recommend 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 of by both the remote party and

the Cisco Unified IP Phone user. A range of outside sources can cause humming or buzzing sounds; for

example, electric lights, electric motors, or large PC monitors. For more information, see

Use, on page

In some cases, use of a local power cube or power injector may reduce or eliminate hum.

Note

These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed

mean that no single headset solution is optimal for all environments.

We recommend that customers test headsets in their intended environment to determine performance prior to

purchase and large-scale deployment.

Note

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G supports wideband headsets.

Beyond physical, mechanical, and technical performance, the audio portion of a headset must sound good to

the user and the party on the far end. Sound quality is subjective and Cisco cannot guarantee the performance

of any headsets or handsets. However, a variety headsets from leading headset manufacturers have been

reported to perform well with Cisco Unified IP Phones.
