Cisco 7941G User Manual

Headset Support
Although Cisco Systems performs limited 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.
Cisco recommends the use of good quality headsets that are screened against unwanted radio frequency (RF)
and audio frequency (AF) signals. Depending on the quality of the headsets and their proximity to other
devices such as mobile 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.
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 the 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, various headsets from leading headset manufacturers have been
reported to perform well with Cisco Unified IP Phones. For details, contact the headset manufacturer.
