USB Ports
Only for Cisco IP Phone 8851.
Your phone may have one or more USB ports. Each USB port supports a maximum of five USB devices.
Each device connected to the port is included in the maximum device count.
For example, your phone can support five USB devices on the side port and five additional standard
USB devices on the back port. Many third-party USB products contain more than one USB device, and thus

Bluetooth and Your Phone
Bluetooth is supported on Cisco IP Phone 8851.
If your phone supports Bluetooth, use a Bluetooth headset and connect your mobile phone or tablet to the phone.
Bluetooth connections work best when you're within 3 to 6 feet (1 to 2 meters) from your phone, but you might be
able to be as far away as 66 feet (20 meters). The Bluetooth connection can degrade if you have a barrier (wall,
door, window), large metal object, or other electronic devices between your phone and the connected device.
To connect a mobile device or headset to your phone with Bluetooth, start by pairing the device with your phone.
You can pair up to three devices. If you try to pair more than three devices, you are prompted to delete one
device.
After the headset or mobile device is paired, the phone connects to the headset or mobile device when the
headset or mobile device is turned on.
When you pair a device, you can set the Bluetooth mode to Phone, Handsfree or Both. Phone allows you to use
only a Bluetooth headset. Handsfree allows you to use only your mobile phone. Both allows you to use both a
headset and a mobile phone.
When you use a Bluetooth headset and mobile devices with your phone, keep these things in mind:
• The last Bluetooth headset or mobile device connected with the phone is the default device that the phone
uses.
• You can have only one active connection at any time. For example, you can have a Bluetooth headset or a
mobile phone active.
• The phone supports one device of each type. For example, you cannot connect two Bluetooth headsets.
• You can connect one mobile device at any time. For example, if your Bluetooth headset is active, and you
connect a mobile phone, the Bluetooth headset disconnects.
• Your Bluetooth device will reconnect if you move back into range, or if it restarts.
