Plantronics CS540 / T48S, headset button won’t hang up call properly

[Jhabers]

We recently moved over our phone system from free PBX to 3CX. I had a working set up with my T48S phone and a Plantronics CS 540 headset. Once we upgraded to 3CX everything works on the headset except when I go to hang up a call from the button on the side of the headset the base clicks a few times but it will not hang up the call. If I push it again it will click again and hang up the phone. Anyone experience this?

I have tried with multiple plantronics headsets and all get the same results. I have swapped out all cables. The only item I haven’t tried to swap was the EHS36. This was all working however before moving to 3CX

Hi,

You need to report this to Plantronics since you are using a 3rd party solution. They might be able to assist you.

Look up their documentation, they might already have information on this.

3CX does not provide any support when it comes to peripherals, so the best thing do do in such cases is to contact the manufacturer directly or check their support pages.

I ended up installing the previous firmware for the phone and it fixed the issue. Must be a big in the latest firmware.
