Bluetooth Wireless Headset Performance
The Cisco Unified IP Phones 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-foot (1- to 2-meter) range. You can connect up to 
five headsets, but only the last one connected is used as the default.
Because there can be potential interference issues, it is recommended that you do the following:
  •
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, can affect 
the connection.
