Works as a combination of our PC35-RJ9Cisco and PC35-RJ9a adapters!
Use your headset with almost any office phone (Avaya, Cisco, Polycom and etc) - 8 settings cover most phone models
Works great with most VOIP phones with a RJ9/Rj10/Rj22 headset jack
Convert two 3.5mm plugs to single 4P4C RJ9/RJ10 headset plug
Does not work with RJ11 jack, which is wider than your headset jack (6 positions vs. 4). RJ11 jack is what is in the wall. RJ9, RJ10, RJ22 are what is on your phone handset or headset.
