Wireless Headsets
You can use a wireless headset with the Cisco Unified IP Phone.
The Cisco website provides information about wireless headsets that work with your IP phone. Go to the
following URL:

See the wireless headset documentation for information about connecting the headset and using the features.
Bluetooth Wireless Headsets
The Cisco Unified IP Phones 9951 and 9971 support Bluetooth wireless headsets.
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. Bluetooth wireless technology operates in the 2.4
GHz band, which is the same as the 802.11b/g band. Interference issues can occur. Cisco recommends that
you:
• Use 802.11a that operates in the 5 GHz band.
• Reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal
objects.
The Cisco Unified IP Phone uses a shared key authentication and encryption method to connect with headsets.
The Cisco Unified IP Phone can connect with up to five headsets at a time. The last connected headset is used
as the default. Pairing is typically performed once for each headset.
After a device is paired, the Bluetooth connection is maintained as long as both devices (phone and headset)
are enabled and within range of each other. The connection typically reestablishes itself automatically if either
of the devices powers down then powers up. However, some headsets require user action to reestablish the
connection.

Potential interference issues can occur. Cisco recommends that you reduce the proximity of other 802.11b/g
devices, Bluetooth devices, microwave ovens, and large metal objects. If possible, configure other 802.11
devices to use the 802.11a channels.
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.
When headsets are more than 30 feet (10 meters) away from the Cisco Unified IP Phone, Bluetooth drops the
connection after a 15- to 20-second timeout. If the paired headset comes back into range of the Cisco Unified
