You've already bought the headset. The problem is your IP phone doesn't natively talk to it. The EHS30 fixes that in about ten seconds. Plug the RJ12 into your IP phone's handset port, jack the 3.5mm lead into your Plantronics, Jabra or Sennheiser module, and you're answering calls from the wireless set without touching the desk unit. Incoming call rings in the earpiece. One button to hang up. No driver, no software, no IT ticket. Just a small box that makes the headset you already own work with the phone you already have
