This product is used to directly connect your headset to specific Avaya IP phones, including the following models: 2410, 2420, 4406, 4412, 4424, 4406D+, 4412D+, 4424D+, 4424LD+, 4610SW, 4620, 4620SW, 4621SW, 5410, 5420, 5610, 5620, 6416D+M, 6424D+M.
The Quick Disconnect (QD) capability allows the headset to detach without losing the call.
This will give you “on-hook” functionality so that you won’t have to lift your telephone handset off the receiver every time when using your Plantronics headset. Only purchase this cable in case you have one of the phone models listed. You will NOT need to purchase a Plantronics amplifier. This cord is all you need in order to connect your Plantronics H-series headset to your phone. The cord has a modular plug at one end and a QuickDisconnect at the other end which connects to any Plantronics Call Center headsets (H-Series).
