Headset

Headset
You can use a wired headset with your Cisco Unified IP Phone. If you use a Cisco Unified IP Phone 7945G,
7965G, or 7975G, you can use a wireless headset with the wireless headset remote hookswitch control feature.

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 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. For details, see the headset documentation.

Phone Cable Lock

You can secure the Cisco Unified IP Phones to a desktop with a laptop cable lock. The lock connects to the
security slot on the back of the phone, and the cable can be secured to a desktop.
The security slot can accommodate a lock that is up to 20 mm wide. Compatible laptop cable locks include
the Kensington laptop cable lock and laptop cable locks from other manufacturers that can fit into the security
slot on the back of the phone.
