Poly APT-31 EHS Cable

Poly APT-31 EHS Cable (Avaya/Tenovis)

The Poly (formerly Plantronics) APT-31 Electronic Hook Switch (EHS) Cable for remote desk phone call control (answer/end). This cable eliminates the need for a HL10 Handset Lifter. This cable works with Tenovis desk phones and may work with additional manufacturers.

Replacement Note: The APT-31 EHS cable replaces the APT-30 cable and features compatibility with the Plantronics On-line Indicator accessory.

Poly has several EHS cables, each being unique to a specific telephone and wireless product.
We strongly suggest confirming compatibility with us before purchasing.
