EHS means Electronic Hook Switch and is a feature that allows wireless headsets to accept and end calls directly by pressing a specific button. 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.

NOTE: A third party accessory is available from Sennheiser, the splitter cable connects the headset's base station to a desktop telephone and the Snom EHS box.
More information regarding the Sennheiser CEHS-SP 01 can be found here.
If you want to know which headsets have been tested for compatibility with Snom Desk Phones, please have a look at the following list: Supported Headsets
But this is not a guarantee that this headset will work perfectly with the Snom EHS adapter.
Attention: Never forget, you have to restart your Snom Desk Phone after connect the Headset with a EHS Adapter to get the Headset working.
Following series/phones currently supporting EHS Advanced:
The connection of wireless headsets, with a transmitter/charger station connected by cable to the desk phone, from third party suppliers (Jabra, Plantronics, Sennheiser) is not always done in the same way. At the moment, there are typically 3 different cases.
Case 1 (default)
Some are connected completely via the Snom EHS Advanced adapter, such as the Plantronics Savi 740, which is connected to the EHS adapter using the 3.5 jack plug (audio) provided with the EHS adapter and then connected to the EHS input of the phone using the cable shown in picture A (see below) and to the headset jack of the phone using the cable provided with the headset. This is the standard case.
Case 3
There are also cases in which an EHS adapter is already included as with the Sennheiser DW Pro 1, in which no additional EHS adapter from Snom is required. (The CEHS-CI 02 cable from Sennheiser should fit here).
Please note that the EHS connection on our phones has changed over time. Older models of the D7xx series (D710, D712, D715, D725, D745, D765) have a 4-pin flat connector, and you need the cable shown in picture D.
Newer devices have an RJ12 Western plug as shown in picture A. Here only the labeling has changed from EXT to EHS over time. The EHS input is mostly hidden behind a black square protection cap.
