Each USB port supports a maximum of five supported and nonsupported devices that are connected to
the phone. Each device connected to the phone is included in the maximum device count. For example,
your phone can support five USB devices such as three Cisco Unified IP Color Key Expansion modules,
one hub, and one other standard USB device on the side port and five additional standard USB devices
on the back port. Many third-party USB products count as multiple USB devices, for example, a device
containing USB hub and headset can count as two USB devices. For more information, see the USB device
documentation.
Note
Bluetooth
Your phone supports Bluetooth Class 2 technology when the headsets support Bluetooth. You can add and
pair up to five Bluetooth headsets to your phone, but the last Bluetooth headset connected becomes the default
for use with the phone.

Your phone provides quick access to your phone lines, features, and call sessions:
•
Programmable feature buttons (left side): Use to view calls on a line or access features such as Speed
Dial or All Calls. These buttons are also called feature buttons.
