Snom EHS Advanced 2.0


The Snom EHS (Electronic Hook Switch) Advanced 2.0 adapter provides the interface between your Snom desk phone and a compatible wireless headset. It is the modern equivalent of the mechanical handset lifter used by wireless headsets. The Snom phone can signal to the wireless headset when the phone is ringing so you can answer and hang up calls remotely, therefore there is no need for a clunky handset lifter. This is designed for maximum productivity in demanding environments.

The following headsets support the Snom EHS Advanced:


  • Compatible with the snom D3XX and D7XX series
  • Complete freedom of movement
  • Signalling of ringtone
  • Call acceptance on headset
  • Call termination on headset
  • Perfect integration of firmware
  • Compatible with Sennheiser's wireless headset range with the use of the CEHS-SP01 EHS adapter cable
  • Vendor specific EHS protocols
  • DHSG Standard
  • No additional power supply required
  • Easy to connect
