    Works perfect. Answer / hang up calls from a Plantronics headset.

    Works perfect. Answer / hang up calls from a Plantronics headset.
    I have a Polycom VVX310 phone and a Plantronics CS510 headset. This little cable lets you answer / hang up calls right from the Plantronics headset. Works perfect. FYI on my particular phone (Polycom VVX310) I had to enable "Plantronics Headset Mode" (per instructions) for it to work properly. This product is VASTLY superior to the physical "headset lifters" available. Highly recommended. Call quality and available max volume also increased (possibly from the stronger connection from the CS510 headset to the VVx310).
