Bluetooth Wireless Headsets
The Cisco Unified IP Phone 9951 and 9971 supports Bluetooth Class 2 technology for headsets that 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 range (1 to 2 meters). You can pair up to 5 headsets, but only the last
headset that was connected is used as the default.
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.
Bluetooth Wireless Headset and Cisco Unified IP Phones
The Cisco Unified IP Phones 9951 and 9971 support Bluetooth wireless headsets.
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.
The Bluetooth icon
indicates whether a device is connected.
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
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.
Handsfree Profile
Your phone supports various Handsfree Profile features that enable you to use hands-free devices (such as
Bluetooth wireless headsets) to perform certain tasks without having to handle 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.
These hands-free features apply to Bluetooth wireless headsets that are used with the Cisco Unified IP
Phone 9951 and 9971:
