Headset

Although Cisco Systems 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.

We recommend that 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 cell 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 large PC monitors. See

information.

In some cases, hum can be reduced or eliminated by using a local power cube or power injector.

Note

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.

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

making a purchasing decision and deploying en masse.
