Yealink Phones with Plantronics Headset issues

[ImpulseElliot]

Recently I have been having a lot of complaints about headset issues with Yealink phones and Plantronics headsets. The most common complaint is that the headset completely stops working requiring a the attached phone to be rebooted completely which fixes the headset for a period of 1-15ish days.

This issue has seemed to happen for T48S, T48U, T57W and T56A Yealink phones. All headsets are Plantronics connected via Plantronics APU76 cables, however I have recently switched some of these out to test using a Yealink EHS40 cable. This is across 5 different 3CX instances over the last few months

All 3CX systems are currently version 16.0.8.9. Phone firmware is all up to date, I have rolled phones back to some slightly earlier versions for testing but seem to have the same issues.

I am a bit unsure of where to go with these options, I am waiting to see how the phones and headsets go over the next week or two using the EHS40 cables but otherwise I am unsure any help would be appreciated.

Hi Elliot,

Thanks for sharing your findings with the community. As for help, you might have better luck contacting the manufacturers directly (ie. Plantronics, and afterwards Yealink if needed). They are more likely to have some better insights on the subject.
