Yealink EHS40 Setup - Sennheiser

This article will show you how to set up your Sennheiser DECT headset with a Yealink EHS 40 cable.

The Yealink EHS 40 cable is not compatible with Leitner headsets, for a Leitner DECT headset, we'd recommend instead the Leitner Electronic Hookswitch for Yealink Phones.

Compatibility Information

The Yealink EHS 40 is compatible with the following Yealink models:

SIP VP59, T58A, T57W, T53W, T54W, T53, T48S, T46S, T42S, T41S

NOTE: If an expansion module has been connected to the SIP- T58A, T57W, T54W, T53W, or T43 IP phone, you can connect the EHS40 to the expansion module

Set Up Instructions

What is in the box: 1 Yealink adapter box with USB cord connection, 1 Sennheiser Y-cord, 1 Plantronics Y-cord, and 1 Jabra Y-cord. For the Sennheiser set-up you will not need the Plantronics or Jabra cables.

1. Grab the Yealink adapter box and the Sennheiser Y-cord (top of the y-cord has an RJ45 and RJ9 connection, the bottom of the y-cord has an RJ45 connection).
2. Connect the bottom of the y-cord into the green PHONE port in the back of the cube
3. Connect RJ45 and RJ9 end of the y-cord into the 2 available slots in the Yealink adapter box
4. Plug the USB cord coming out of the adapter box into the USB port in the phone
5. Move Dipswitch #1 down (bottom right in back of cube) and ABC switch on A

NOTE: If the Yealink EHS 40 does not immediately give ring detection, we may need to get to the web portal and do the following:

In the Yealink phone web portal > Features > Audio > Ringer Device for Headset, then choose Use Headset & Speaker. The below picture for your reference.
