Audio Quality

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.

In some cases, hum may 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.

Cisco recommends that customers test headsets in their intended environment to determine performance before

making a purchasing decision and deploying on a large scale.

Audio Quality

Beyond 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 are reported to perform

well with Cisco Unified IP Phones.
