Lately I've been getting asked the question "what does DHSG stand for on the bottom of my Discover D900 charging base?". DHSG is a german acronym that I can't pronounce which means "wireless headset". If you look at the image below you will see DHSG and RHL (Remote Handset Lifter).
DHSG refers to the EHS (Electronic Hook Switch) standard which is used to convert a wireless headsets internal signals to a specific standard that many more recent phones support.
When you use a wireless office headset, there's only 1 of 2 accessories you would have to purchase in order to have the ability to answer or end your phone calls directly from your wireless headset. If you have a more modern phone like: Cisco, Polycom, Avaya, Snom, Siemens or Aastra, chances are they operate on the DHSG standard which allows for you to use an EHS cable with your headset and phone.
If you use some sort of Analog telephone, then most likely you would need a Handset Lifter (Follow our full blog on what is a handset lifter). This is a device that is compatible with just about every type of corded office phone on the market. A Handset Lifter is a mechanical device that uses double sided tape and mechanically lifts and lowers your handset in order to answer or end phone calls directly from your wireless office headset.
To sum everything up the DHSG standard is a protocol between specific phones and wireless office headsets that give you to ability to use an EHS cord. Ultimately, giving you the ability to answer/end your phone calls remotely with your wireless headset.
