Changing DHSG Settings in a Mitel 6900 Series Phone (Audio path)

Leitner EHS cable for Mitel phones and remote answering

Mitel phones tend to have different menus than what their manuals show for some reason. So if this isn't successful, we have had success with having their IT department (or phone people) set it to DHSG mode on the back end.


1) To enable/disable DHSG headset mode on the MITEL 6940 phone:

  • Press the “Settings” key to enter the Static Settings menu
  • Navigate to the Audio > Audio Path > Select “Headset” setting and save

Note: May need to set it to "Headset/Speaker" in order for it to work

  • Next, Navigate to Audio > Headset > DHSG and use navigation key to change setting to “Enabled”
  • Press the “Save” soft key to save your changes

Note: If Bluetooth headset is paired to this phone, it will take precedence over a USB headset. If you want a corded headset to work with this phone, you will need to deregister any Bluetooth headset.
