These Shoretel phones, Toshiba phones and Allworx Paetec phones support native "load detect" (LD) therefore no HL10 handset lifter is needed. This RD-1 ring detector will provide a beep tone in your earpiece to alert you to a new call coming in. Simply press the button on your earpiece from anywhere within your range to answer/end your call.
NOTE: If you have one of the following ShoreTel (Mitel) phone models: IP480, IP480G, IP485, IP485G, IP655 you will need the APD-80 EHS cord instead of this RD-1 ring detect pod.
