Chapter 3 Setting Up the Cisco Unified IP Phone Understanding the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE Components The primary reason that support of a headset would be inappropriate for an installation is the potential for an audible hum. This hum can either be heard by the remote party or by both the remote party and the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, being near electric motors, large PC monitors. In some cases, a hum experienced by a user may be reduced or eliminated by using a local power cube. See the "Safety" section on page 3-3 for more information. Audio Quality Subjective to the User Beyond the 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 is subjective and Cisco cannot guarantee the performance of any headsets or handsets, but some of the headsets and handsets on the sites listed below have been reported to perform well on Cisco Unified IP Phones. Nevertheless, it is ultimately still the customer's responsibility to test this equipment in their own environment to determine suitable performance.
