Third Party Headsets

Cisco performs internal testing of third-party headsets for use with Cisco IP Phones. But Cisco does not certify

or support products from headset or handset vendors. Check with the headset manufacturer to confirm whether

you can use it with your Cisco phone.

Note

The Cisco IP Phone 7811 does not support a headset.

Headsets connect to your phone using either the USB or the auxiliary port. Depending upon your headset

model, you have to adjust your phone's audio settings for the best audio experience, including the headset

sidetone setting.

If you have a third party headset, and you apply a new sidetone setting, then wait one minute and reboot the

phone so the setting is stored in flash.

The phone reduces some background noise that a headset microphone detects. You can use a noise canceling

headset to further reduce the background noise and improve the overall audio quality.

If you are considering a third part headset, we recommend the use of good quality external devices; for example,

headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending

on the quality of headsets and their proximity to other devices, such as mobile phones and two-way radios,

some audio noise or echo may still occur. Either the remote party or both the remote party and the Cisco IP

Phone user may hear an audible hum or buzz. A range of outside sources can cause humming or buzzing

sounds; for example, electric lights, electric motors, or large PC monitors.

Sometimes, use of a local power cube or power injector may reduce or eliminate hum.

Environmental and hardware inconsistencies in the locations where Cisco IP Phones are deployed mean that

no single headset solution is optimal for all environments.

We recommend that customers test headsets in the intended environment to determine performance before

making a purchasing decision to deploy on a large scale.
