Avaya EHS Cables and Headset Adapters
Avaya EHS Cables for Every Desk Phone in the Range
An Avaya EHS cable carries the electronic hook-switch signal that lets a wireless headset answer your desk phone remotely — and the connector is decided by your phone model, not your headset. J100, 1600 and 9600 series handsets use HIS. The older 1400 through 9400 range uses HIC. Savi and CS500 wireless bases pair via the APV-63 adapter. Every cable here is live stock from Plantronics, Jabra and Sennheiser.

Choosing the Right Avaya EHS Cable by Phone Family
The avaya phone headset jack is either a modular RJ9 socket (HIS family, J100 through 9600 series) or an older digital HIC connector (1400 through 9400 series). EHS cables follow the same split; the phone decides the cable, and the cable decides what headset system will work. For wireless headsets on the Plantronics platform, the avaya headset adapter APV-63 or APV-66 replaces the EHS cable entirely with a wireless pairing port at the HIS socket. Match your phone series in the table before ordering.
| Phone series | Cable type | In-stock models | Function |
|---|---|---|---|
| J100, 1600, 9600 | HIS | Plantronics HIS, Jabra Link 19/20/32/33/35, Sennheiser CEHS-AV 03/05 | EHS remote answer |
| 1400, 2400, 4600, 5400, 9400 | HIC-10 | Plantronics HIC-10 | EHS remote answer |
| Savi / CS500 wireless base | APV-63 / APV-66 | Plantronics APV-63, APV-66 | Wireless pairing port (DECT/Bluetooth) |
| Any Avaya RJ9 phone | QD-to-RJ9 cord | Jabra GN1216, GN 1200 Smart Cord | Direct QD connection, no EHS |
The Plantronics APT-31 and ring-detector cable cover older analogue and digital Avaya models not in the table. The PJ-327 dual-prong adapter rounds out the range for remaining phone types. For direct-connect headsets with a QD plug, the Jabra GN1216 is the avaya phone headset adapter that reaches the RJ9 socket without an EHS module.
FAQ
Frequently Asked Questions
Avaya J100, 1600 and 9600 series phones use an HIS-socket EHS cable. Options in this collection include the Plantronics HIS cable, the Jabra Link 19, 20, 32, 33 and 35, and the Sennheiser CEHS-AV 03 and 05. All carry the hook-switch signal that enables remote answer from a paired wireless headset base.
No. Avaya EHS cables are manufacturer-specific: a Jabra Link cable connects only to a Jabra headset base, a Plantronics HIS or HIC-10 cable connects only to a Plantronics or Poly base, and a Sennheiser CEHS-AV cable connects only to a Sennheiser base. Match the cable brand to the headset brand — a cross-brand combination will not pass the hook-switch signal.
An Avaya EHS cable — such as the HIS or HIC-10 — runs between the phone's headset port and a wireless headset base, which then communicates with the headset wirelessly. An Avaya Bluetooth adapter such as the APV-63 or APV-66 also plugs into the HIS port but adds a wireless pairing interface directly, so no separate EHS cable is needed in the chain. Both enable remote answer from the headset; the adapter removes one physical cable from the desk.
