Cisco DX70 and DX80  Administrator Guide
Bluetooth headset
Bluetooth headset is supported on DX70 and DX80. 
•  Bluetooth profiles supported: 
•  HFP (Hands-Free Profile)
•  A2DP (Advanced Audio Distribution Profile)
•  The headset must support both HFP and A2DP or HFP-
only. Headsets with A2DP-only is not supported.
•  Bluetooth headset is supported directly with the embedded 
Bluetooth radio or using a USB Bluetooth dongle. 
•  Multiple headsets can be paired to the video system, but only 
one can be connected at a time. 
•  The range is up to 10 m (30 ft). If you move outside the range 
when in a call, the audio will switch to the speakers on the 
video system. 
•  Most headsets have built in volume controls. When in a call, 
the volume of the headset and video system is synchronized. 
When not in a call, the volume buttons on the headset and 
video system operates independently.
Supported Bluetooth features:  
•  Answer incoming calls
•  Reject incoming calls
•  Hang up calls
•  Volume up and down
•  Some headsets have mute control. This operates 
independently from the mute control on on video system.
USB Bluetooth dongle
•  Using the USB Bluetooth dongle is advisable as it gives better 
audio quality. 
•  When using a USB Bluetooth dongle the headset is detected 
as a USB headset. 
•  There will be no synchronization of headset volume and video 
system volume when using a dongle. 
•  We have tested Jabra Link 360, Plantronics BT300 and 
Plantronics BT600; though others might work as well.
