Very easy to hook up, though the directions were more IKEA-like than I prefer (i.e., pictures only, no explanations). One thing that looked like a small microphone was supposed to be attached to the phone around the area of the speakerphone but from the diagram it was hard to tell if it was supposed to go on the TOP of the phone or under it. Either way there is no explanation of what it's for, and in our case it doesn't seem to matter if it's attached or not, it works either way.I'm glad not to need a mechanical lifter any more, as it was sometimes problematic.

The adapter works flawlessly with Plantronics CS540 headset allowing handsfree operation when answering calls.

For some reason after connecting this adapter my mic doesn’t work anymore and calls are static or dropping.

My 15 year old Plantronics wired binaural headset went out on me so it was time to get a new solution.I didn't think I was going to be able to find a wireless solution for my 15 year old Avaya 6416D+M phone but thanks to Plantronics very helpful compatibility guide, I discovered that the CS520 is compatible!I absolutely LOVE this thing!The quality of the audio is great and the clarity is impressive! Super easy to install and seems to charge fairly quickly.I purchased the Plantronics APV-63 EHS Adapter (Avaya) that I can answer calls by touching the button on the headset without being close to your desk. Real nice!So, I originally included a link to a very useful Plantronics compatibility page so that you can see if your phone is compatible with this headset but I was forced to remove that link. Say, Thank you Amazon!! That link was intended to help their sales not hurt them.

After extended time with Plantronics Customer Support, the issue with our headset was narrowed down to this adapter. The ability to hear the person on the other end does not work. You can hear them for awhile and then it goes quiet. Happens frequently. Wish we could get it replaced. It's too bad that won't warranty the product for even a year.

Information of how this works and should be connected is very scares on the web but was able to make it work with my phone system

Works perfectly with my company issued Avaya 9608 and Plantronics Savi 740 (WO2) headset.Pickup and hangup exactly as expected.I only connected the RJ11 connector, did not need the mic.Yes, the price is quite high, but calculated over many years of usage, several hours a day, totally worth it.Fast shipping and well packaged.
