Poly APP-51 EHS Cable (Poly/Polycom)

The Poly (formerly Plantronics) APP-51 Electronic Hook Switch (EHS) cable communicates electronically with your desk phone giving your wireless headset call control. The APP-51 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 Poly (formerly Polycom) desk phones and may work with additional manufacturers.

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

10 reviews for Poly APP-51 EHS Cable

  1. CBcpc –

    the first cable I got was defective and they replaced it in 2 days

  2. Edie –

    This Electronic Hook Switch eliminates the need for a clunky handset lifter. It provides a professional capability to a small business for a very affordable price. I would highly recommend this to give any small business a big business feel!

  3. Pam –

    To answer and hang up without being at your phone, this is a must have.

  4. ThatChr1s –

    Very simple review because it works just like it says it should. Very easy to install between the headset and the Polycom phone.

    No issues. Just a great product.

  5. Fred –

    Works great in connecting my Platronics headset to my new Polycom phone.

  6. Audie –

    Our office staff is so happy we purchased this cable. We can easily answer our phones if we are away from our desk, and it made our jobs much easier.

  7. John –

    Product works for purpose indicated.

    I purchased wrong item, and Headsets Direct helped me get it straightened out. Allowed the return of wrong item and replaced with the correct one. All done very quickly, efficiently and at no expense.

    I am pleased with their knowledge and service.

  8. Marty –

    These cables really helped our Receptionists so the headset button automatically opens the line. It really saved them some steps in answering calls.

  9. slight problem –

    Everything about this cable was great, except the VVX201 model phone I have has the headset jack and phone jack are not in the same place and the cables that form the Y were too short to make the connection. An inch longer on either one would have done it. We had to buy another cable to make it reach. I think the VVX201 is the only polycom model that has the headphone jack not in line with the other connections on the base of the phone, so this is probably isolated to just that model. We called plantronics and even the person on the help desk was surprised by that. With the adapter, everything is great.

  10. KM –

    Very happy with my purchase. Easy to use and works great. I highly recommend this.
