Understanding the Cisco Unified IP Phone Components Chapter 3 Setting Up the Cisco Unified IP Phone 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.

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. See manufacturer's sites for details.
