#### **My headset is listed, but the buttons (answer & hang up) do not work:**
Here you will find known solutions to the problem:
**Cause:** Built-in Bluetooth of the computer/laptop or any Bluetooth-USB dongle is being used\
**Solution:** Use the original Jabra Link 380 dongle or a cable connection with USB-C
**Cause**: The headset is controlled by another VoIP/SIP app such as Teams/Discord\
**Solution**: close the other application, then try the headset buttons again
**Cause 1:** MacOS/Win BT Jabra headset connected via Bluetooth\
**Solution 1:** Plug in MacOS/Win BT USB Link 380/390 and connect the BT headset via it\
**Cause 2:** Linux + any headset\
**Solution 2:** unknown

#### **My headset is not listed, does it still work?**
The voice transmission will work with any headset.\
There may be limitations for the headset buttons / base buttons for answering/rejecting calls, hold. In this case, users can then answer the call via the app + mouse click.\
If the headset buttons work or do not work for a specific headset model, we are happy to update the list. You are welcome to do so via the [contact form](https://help.sipgate.de/hc/de/requests/new?ticket_form_id=55321&_gl=1*t9ijn9*_gcl_au*MjA0NTg3NzM0NC4xNzU3MDU1MzY5#anfrage) contact us on our website.
#### **My headset buttons don't work, how can that be changed?**
You can report the adjustment for button support for headset manufacturers + models here
\
We then collect the demand and check how we can adapt button support from current HID to the respective manufacturer's protocol.
#### **Known bugs and solutions**
Error: Headset not detected / headset buttons do not work
**Cause**:\
Built-in Bluetooth of the computer/laptop or any Bluetooth-USB dongle is being used but headset buttons do not work\
**Solution**:\
Use the original Jabra Link 380 dongle or a cable connection with USB-C
Error: Microphone does not work despite being selected
**Cause**: Headset is in audio playback mode\
**Solution**: Flip out the microphone boom once or select Headset twice and change selection to “Headset Communication Device”
Error: Headset with jack connector: microphone recording very quiet
**Cause**: jack microphone headset digital (laptop microphone) is selected\
**Solution**: select jack microphone headset stereo (headset microphone)
Error: Headset buttons do not work
**Cause 1.1**: In the sipgate app ➔ Settings ➔ Audio, check whether headset function keys are active\
whether HID device selection may be empty\
whether HID device selection: a headset icon is visible behind the headset
\
**Solution 1.1:**\
Enable headset function keys in audio settings\
HID devices: select headset; if selection is empty: make sure a headset icon is visible behind the headset
\
**Cause 1.2**:\
\- if the headset icon behind the headset is missing, HID was not recognized\
\- alternative BT adapter instead of manufacturer BT adapter: e.g. Link 380/390\
\- Linux cannot do HID\
\- MacOS: USB-C and/or BT often cannot do HID
\
**Solution 1.2**:\
\- MacOS/Win: use the manufacturer's USB BT adapter\
\- MacOS/Win: try USB-C and BT to see when/where HID is recognized\
\- Linux: unknown\
\- report manufacturer + model + button support here as a request: [App | sipgate](https://feedback.sipgate.de/b/app)\
**Workaround 1.2**: answer call via keyboard / mouse
