You can use a standard headset with your desk phone. Standard headsets plug into the headset jack on the
back of the phone with an RJ-type connecter.

Caution
Procedure

Connect a USB Headset
When you use USB headsets with your phone, keep in mind the following:
• You can use only one headset at a time. The most-recently connected headset is the active headset.
• If you are on an active call and unplug a USB headset, the audio path does not change automatically.
Press the Speakerphone button or pick up the handset to change the audio.
Your phone may have more than one USB port, depending upon your model. The Cisco IP Phone 8851 and
8851NR has one USB located on the side of the phone. The Cisco IP Phone 8861, 8865, and 8865NR have
two USB ports, located on the back and side of the phone.
You may have to remove the plastic cover to access the side USB ports.
