Here is the direct link for the Leitner EHS for Avaya Phones mentioned in this article

This Avaya hookswitch is designed to work alongside the RJ9 cable that comes with the Leitner wireless headsets. Set-up instructions are below.

Leitner Avaya EHS Setup

1. Head to your base unplug the power cable from the back of the base and set the RHL/DHSG button on the bottom of the Leitner charging base to RHL
2. Next get EHS cable. This is the cable with one larger end that goes through a little box. Connect the RJ45 end to the AUX jack on the back of the Leitner charging base (this is the largest jack in the center of the base). Connect the other end of this cable to the AUX jack in the back of the Avaya telephone
3. Now get the cable without the box that came with the Leitner. Connect one side of this cable to the telephone connector jack in the back of the Leitner charging base (this is the jack second to the left). Connect the other side of this cable to the headset jack of the Avaya telephone
4. Take the external microphone and plug the metal pin into the pin jack on the EHS cord box, remove the waxy paper from the microphone, then stick it to the speaker on your phone
5. Then, plug the power cable back in at the back of the base
6. Compatibility switch on the bottom of the base should be set to 1

Note 2: If you are using an Avaya 5420 and have a sidecar attached, you will not be able to plug this hookswitch into the phone, as the sidecar takes up the port we need. However, if you use the other Leitner EHS cord for Avaya phones (CAT #2339), it will work by bypassing the port that was taken up by the sidecar.
