Bluetooth Wireless Headset Performance
The Cisco Unified IP Phone 9951 and 9971 support Bluetooth Class 2 technology when the headsets
support Bluetooth. Bluetooth enables low bandwidth wireless connections within a range of 30 feet
(10 meters). The best performance is in the 3 to 6 feet (1 to 2 meter) range. You can connect up to five
headsets, but only the last one connected is used as the default.
There can be potential interference issues; therefore, it is recommended that you:
• Reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large
metal objects.
• Use the Cisco Unified IP Phone on the same side of the body as the Bluetooth-enabled headset.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone,
but some barriers, such as walls or doors, and interference from other electronic devices, could affect
the connection.
