For a list of supported headsets, see http://www.cisco.com/c/en/us/products/unified-communications/ucphone_headsets.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.
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.
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.
enable the headset and then add it as a phone accessory.
The phone supports various Handsfree Profile features that enable you to use hands-free devices (such as Bluetooth wireless headsets) to perform certain tasks without handling the phone. For example, instead of pressing Redial on the phone, users can redial a number from their Bluetooth wireless headset by following instructions from the headset manufacturer.
hands-free features apply to Bluetooth wireless headsets that are used with the
Cisco IP Phone 8851 and 8861:
Hands-free devices may differ as to feature activation. Device manufacturers may also use different terms when referring to a feature.
Only one headset type works at any given time. If you use both a Bluetooth headset and an analog headset that are attached to the phone, enabling the Bluetooth headset disables the analog headset. To enable the analog headset, disable the Bluetooth headset. Plugging a USB headset into a phone that has Bluetooth headset enabled disables both the Bluetooth and analog headset. If you unplug the USB headset, you can either enable or disable the Bluetooth headset to use the analog headset.
