Fix Yealink Phone Headset Not Working Despite Correct Connection

Hey guys, quick question. I have a Yealink phone, we are trying to use a headset. It works in another phone, same brand,same model, but not in this one. Is there any configuration or something? we already tried to reboot the phone, no luck. When she press the headset button, she can't hear anything.

what type of headsets? Yealink model?

yes

probably connected to the wrong port. its a dummy device, no settings needed. confirm they connected it to the correct port on the phone

It's plugged in into the correct one, the one that has the headset logo 🫤

And it's a brand new phone

did you try a firmware update for the phone?

did you request a pic to confirm that?

also, on the phone itself you have to press the button to switch to the headset

Yes, she knows how to use them

We already tried with that headset button

assuming everything is plugged in correctly, its the issue with the phone.
