The IQ333EHS analogue (POTS) telephone offers Electronic Hookswitch (EHS) integration to suit most previous and all current and most previous models of Poly PlantronicsTM professional DECT wireless headsets*. 
*The EHS feature eliminates the need for a mechanical handset lifter: pressing the "Call" button on your headset prompts the telephone to answer the call automatically.
The PlantronicsTM On Line Indicator (OLI) is also supported by connecting the PlantronicsTM OLI to the dedicated OLI port (pictured below) on the side of the IQ333EHS. Suitable for large and small including enterprises, home workers and SMEs.
Supplied with an EHS cable (pictured below), this product is ready to connect to all DECT wireless Poly PlantronicsTM headsets* that are equipped with a 3.5mm lifter port.
