Ordering a corded headset for an Avaya phone comes down to one thing: matching the right cable to your exact phone model. The headset itself is usually the easy part — any Plantronics H-Series headset works across the board — but the cable that connects it to your specific Avaya phone varies, and getting it wrong means a headset that won't work at all.

Which cable does your Avaya phone need?
Start with any Plantronics H-Series headset, then find your phone model in the table below to identify the correct cable.
| Avaya phone model(s) | Cable needed |
|---|---|
| 46xx, 56xx, 24xx, 54xx series, 6416D+M, 6424D+M, QE4610 (e.g. IP 2410, 2420, 4610, 4620, 4621, 4622, 4625, 4630, 5410, 5420, 5610, 5620) |
Plantronics HIC cable |
| 96xx series, 1608, 1616 (e.g. IP 9620, 9630, 9640, 9650, 1608, 1616) |
Plantronics HIS cable |
| 46xx IP phones (4606, 4612, 4624) | Plantronics HIC-10 cable |
| AT&T / Lucent / Avaya Merlin Magix (4424LD+, 4424D+, 4412D+, 4406D+) | Plantronics HIC cable |

Myth
If a cable works on one Avaya Call Master model, it works on all of them.Reality
Not with the Call Master line specifically. Call Master I, II, III, and IV use the Plantronics P10 amplifier, but Call Master V and VI need an entirely different part — the Plantronics 26716-01. And Call Master V/VI phones do not support wireless headsets at all, unlike the earlier Call Master models, which can pair a Plantronics wireless headset with the PJ-327 2-prong adapter. If you have a Call Master phone, confirm exactly which generation before ordering.Wireless headsets for Avaya Call Master phones
If you have a Call Master I, II, III, or IV and want wireless instead of corded, any Plantronics wireless headset works with the Plantronics PJ-327 2-prong adapter. If you have Call Master V or VI, wireless headsets are not compatible with these phones — corded is the only option.
Connecting the headset once you have the right cable
Once you've matched your headset and the correct cable — both ends use quick-disconnect connectors — the setup is simple: the cable's modular RJ9 jack plugs directly into your Avaya phone's headset port. No amplifier is needed for phones with a dedicated headset port; the cable alone completes the connection.

Which cable do I need for my Avaya phone?
It depends on your exact model. Avaya 46xx, 56xx, 24xx, and 54xx series phones use the Plantronics HIC cable; 96xx series and 1608/1616 phones use the HIS cable; older 46xx IP phones (4606, 4612, 4624) use the HIC-10 cable. Check the full model table to confirm which cable matches your phone.
What headset works with an Avaya Call Master phone?
Any Plantronics H-Series headset works, but the connection differs by generation. Call Master I, II, III, and IV use the Plantronics P10 amplifier, or a wireless headset with the PJ-327 2-prong adapter. Call Master V and VI require a different part, the Plantronics 26716-01, and do not support wireless headsets at all.
Can I use a wireless headset with an Avaya Call Master phone?
Only with Call Master I, II, III, or IV, using any Plantronics wireless headset plus the PJ-327 2-prong adapter. Call Master V and VI phones do not support wireless headsets under any configuration — corded is the only option for those models.
Do I need an amplifier for a corded headset on an Avaya phone?
Most modern Avaya phones (46xx, 56xx, 96xx, 24xx, 54xx series) have a dedicated headset port, so a headset plus the correct bottom cable connects directly with no amplifier needed. Call Master I-IV phones are the exception, requiring the P10 amplifier instead of a direct cable connection.
The whole decision comes down to matching your exact Avaya phone model to its cable — get that right and any Plantronics H-Series headset connects directly through the RJ9 headset port. Still not sure which cable your phone needs? Call our team at 877-999-3838 and we'll confirm it in a minute.
