Understanding the Cisco Unified IP Phone Components
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 Using
External Devices, page 3-5, for more information.
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.
Note The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G support wideband headsets.
Audio Quality Subjective to the User

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. See manufacturer’s
sites for details.
