Poly 3.5mm EHS Cable (Panasonic) – Poly 84757-01 or HP 85R17AA

The Poly (formerly Plantronics) 3.5mm Electronic Hook Switch (EHS) cable part # Poly 84757-01 or HP 85R17AA communicates electronically with your desk phone giving your wireless headset call control. The 3.5mm EHS allows ring alerts to sound in your headset as well as answer and end calls remotely.

This cable eliminates the need for a HL10 handset lifter. This cable works with Panasonic desk phones and may work with additional manufacturers.
