Issue with headsets, calls are spontaneously ended

[sanderv85]

Hello,

Some of my customers are having strange problems.
It seems that sometimes the phone/headset is automatically connecting.
This results in call that are abruptly ended of answered.
Also when nobody is touching the phone or headset it does this.

It happens with different combinations Yealink phones or headset brand.
For instance Yealink T46U/Plantronics W8220T/EHS40 or Yealink T46S/Jabra 920/EHS36.

I have tried updating the phones/headsets/ehs, replaced switches/routers etc.

Do other people experience the same strange problems and maybe have a solution?

Thanks in advance.

Kind regards Sander
