Never miss a call again using your Discover Adapt 30 wireless headset! Add the DHS14 Electronic Hook Switch Cable with your Adapt 30 wireless headset and Polycom phone and you'll be able to answer/end calls when away from the phone up to 350 feet!
While I am not overly thrilled with the high price, it does get the job done. It is also in line with OEM cables for similar products.
It worked fine with the Polycom phone
