Wireless Headsets
You can use most wireless headsets with your phone. For a list of supported wireless headsets, see
http://www.cisco.com/c/en/us/products/unified-communications/uc_endpoints_accessories.html
Refer to your wireless headset documentation for information about connecting the headset and using the
features.
Bluetooth Wireless Headsets
For a list of supported headsets, see http://www.cisco.com/c/en/us/products/unified-communications/uc_
endpoints_accessories.html .
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.
Cisco IP Phones use a shared key authentication and encryption method to connect up to fifty headsets, one
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.
The Bluetooth icon indicates that Bluetooth is on, regardless of whether a device is connected or not.
Potential interference issues can occur. We recommend 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. Use 802.11a, 802.11n or 802.11ac that operates in the 5 GHz band.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone.
However, 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 IP Phone, Bluetooth drops the connection
after a 15- to 20-second timeout. If the paired headset comes back into range of the Cisco IP Phone and the
phone is not connected to another Bluetooth headset, the in-range Bluetooth headset automatically reconnects.
For certain phone types that operate in power-save modes, the user can wake up the headset by tapping on
the operational button to initiate the reconnect.
You must enable the headset and then add it as a phone accessory.
