Set up your Plantronics headset with a Snom EHS
- Grab the phone cord that came with the headset and plug the big end into the back of the headset base in the phone port, then plug the other end into the headset port of the phone
- The RJ12 cable (Part A) will plug into the EHS adapter and the EHS/EXT port on the phone
- The 3.5mm cable will plug into the EHS adapter and the other side will connect to the 3.5mm port on the headset base, right next to the phone port
- Set switch on the bottom of the headset base to A
And that should do it!
