APV-63 Electronic Hookswitch

Poly APV-63 Electronic Hook Switch (85R01AA) is a cable accessory for remotely answering and ending calls on Avaya desk phones. It connects the headset call control to the desk phone, allowing call handling without reaching for the handset.

The cable is 10.0 ft long, offering a wired connection between the phone and headset setup. The listing identifies it as a way to use electronic hookswitch control without an HL10 handset lifter. It is the APV-63 model, previously numbered 38734-11, and replaces the APV-62 EHS cable.

The listing also notes compatibility with the Plantronics On-line Indicator accessory. This makes the cable useful in a compatible office headset arrangement where call answer and end control from the headset is desired.
