Accessories/EHS
From Snom User Wiki
EHS means Electronic Hook Switch and is a feature to enable certain wireless headsets to answers and terminate calls directly from the wireless headset device by pressing a designated key. In other words, apart from the pure speech transmission, EHS makes call acceptance possible directly at the headset. By using EHS, telephones and headsets of different manufacturers can be combined. The snom EHS solution supports both wireless headsets from GN Netcom/Jabra as well as devices from Plantronics. This requires a corresponding connector at the headset.
The snom EHS solutions consist of an EHS adapter box and necessary cables. There are two EHS adapter versions:
- (not manufactured anymore) Wireless Headset Adapter: P/N: 00001203
- (new from 02/2010): EHS Advanced: P/N: 00002362
Please choose the appropriate product from the following overview:

- NOTE:
- (snom 3xx only) To use an expansion module and a wireless-headset adapter simultaneously you need a Y cord, since both plug into the connector labeled EXT
on the back of the phone.
- You don't have to register the EHS device in the phone menu. Just connect it and restart the phone. It automatically detects the adapter.
