Headsets cannot answer/end Teams phone call

[uwige845]

Hello community,

i have a Voyager Legend UC, Voyager 4300 UC and Calisto 5300. They appear to have the same issue.

When the device is connected to the laptop (Windows 10) with the dongle (BT300 or BT600), all softphone functions work fine, including volume +/- and mute. The mute is also synced with MS Teams. But I can never pick up or end MS Teams phone calls. When Teams is ringing, and I press the Teams button on the device, it will prompt with "answering call", but it doesn't actually pick up. I've called Poly Support but they could only assume it's a PC compatibility issue without any solution. Has anyone encountered this issue?

I have also several small issues with a Poly Focus II headset with Office BAse.

We have approx 200 devices and all experiencing small issues.

Auto answer not always working. (50% of the time)

Button not always working.

Office base doens't end the call although call is ended in Teams with the result that you have several issues the next time someone call.

Poly helpdesk doesn 't take us serious and does nothing....
