Box Contains APP-51 Cable Review: Great bit of kit - Great bit of kit that allows me to answer calls remotely between my VVX411 & Savi headset. Not cheap and should really be built into the base station for my headset, but it's not me paying for it so I'm not bothered (just got to try and tidy up all the extra cables). Next day delivery was great and I've no complaints! Review: Works perfectly - Made my Plantronics Savi 740 headset work seamlessly with a Polycom VVX400 VOIP Phone, essentially means I can answer calls away from my desk without the need of pressing the answer button on the phone every time it rings. Seems expensive but its essential. ## Features - Electronic Hook Switch Cable for remote desk phone call control (answer/end).

Issues like the call fading out where you can no longer hear the other person.** A: YES, I use Plantronics headsets and these cables at work and it is a common issue (globally) for some APP-51 adapters with the certain HW-Release like 02/16 A41.02 or 07/18. We get Echo-Issue, calls fading and dropping completely. The only solution to this that proved efficient is a different HW Release. **Q: Will this work with a polycom vvx201 phone?** A: It works on my polycom vx310 phone. **Q: Will this work with a vvx250?** A: Hello! Yes, it is compatible. If you have any further questions, feel free to contact our Customer Care Team at: 800-985-9815. **Q: Is this ( plantronics ehs 38439-11 ehs app-51 hook switch landline) is the correct adaptor for a plantronics cs530? i have a cisco 7975 phone. thanks** A: Thank you for your question. This cable is ONLY for POLYCOM phones. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great bit of kit *by T***E on 27 September 2024* Great bit of kit that allows me to answer calls remotely between my VVX411 & Savi headset.
