• If you are listening to music through the Bluetooth source, the music pauses when you place the headset
on the base.
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.
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.
You can use only one headset at a time. The most-recently connected headset is the active headset.

Bluetooth Headsets
You can use a Bluetooth headset for your calls if your phone supports Bluetooth.
When you use Bluetooth headsets with your phone, keep in mind:
• If you have both a Bluetooth headset and a standard headset attached to the phone, only one type of
headset works at any time. When you enable one headset, the other is automatically disabled.
• If you use a USB headset, both the Bluetooth and analog headset are disabled. If you unplug the USB
headset, you need to enable the Bluetooth or standard headset.
• For optimum headset coverage, use your Bluetooth headset within 10 feet (3 meters) of the phone.
• Your phone supports the Bluetooth Handsfree Profile. If your Bluetooth headset supports these features,
you can use your headset to:
