Has anyone had this cable go bad after a year or so? Issues like the call fading out where you can no longer hear the other person.

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.

Will this work with a polycom vvx201 phone?

It works on my polycom vx310 phone.

Will this work with a vvx250?

Hello! Yes, it is compatible. If you have any further questions, feel free to contact our Customer Care Team at: 800-985-9815.

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!

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.

This is apparently the right EHS for my phone but the headset still drops out every 60s.

Connect Savi 740 headset to Poly CCX600

Paired a Plantronics Savi 740 to new Poly CCX 600 phone and now can answer and hang up remotely. After a few days of use however I got a lot of complaints that audio quality was poor. I am guessing this is because this routed audio through the old analogue channel. I plugged another headset into the phone via USB so the digital input and the sound was perfect. Something to be aware of!
