Third Party Headsets

Number

You use the source control buttons on the base to control the active source. Each source button corresponds

with a specific connection on the multibase.

Even if you are connected to a source, the LED may not be lit. The source LED only lights when the source

is selected or has an active call. For example, you may be properly connected to a Cisco IP Phone, your PC,

and your mobile phone through Bluetooth. However, the respective source LED is only lit when it is selected,

has an active call, or has an incoming call. Press the source button to check if a source is properly connected.

The source LED flashes three times if there is no connection.

You can alternate between active call sources.

Note

Place an active call on hold before you change to a different call source. Calls on one call source aren't

automatically put on hold when you switch to a different call source.

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
