Headsets
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.
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 can affect the connection. Interference from other electronic devices can
also affect performance.
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. The paired headset reconnects when it is comes back into range of the Cisco
IP Phone. For certain phone types that operate in power-save modes, you can wake up the headset by tapping
on the operational button.
Enable the headset before you add it as a phone accessory.
The phone supports various Handsfree Profile features that allow you to use devices such as Bluetooth wireless
headsets for certain tasks. For example, instead of pressing Redial on the phone, you can redial a number from
the Bluetooth wireless headset by following instructions from the headset manufacturer.
Cisco IP Phone 8811, 8841, 8851NR, and 8865NR do not support Bluetooth wireless headsets. These hands
free features apply to Bluetooth wireless headsets that are used with the Cisco IP Phone 8845, 8851, 8861
and 8865:
• Answer a call
• End a call
• Change the headset volume for a call
• Redial
• Caller ID
• Divert
• Hold and Accept
• Release and Accept
Hands free devices have different feature activation methods. Device manufacturers may also use different
terms when referring to the same feature.
Important
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
the Bluetooth headset or disable the Bluetooth headset to use the analog headset.
