Microphone problem on windows 10 and 3cx client 15.5.12227.5

[Valerio]

My company uses 3CX PBX and we have some problems with Jabra microphone on Windows 10 Pro and 3CX client 15.5.12227.5. Sometimes when we make/receive a call microphone doesn't work. It seems that this problem happens on first call after 3CX client has started (usually when we startup pc in the morning).
Jabra micr works properly with all the other applications installed on PC (like Skype).
Have you some suggestions?
Thanks in advanced

Try following the steps in the guide below to allow usage of your Microphone by applications installed on your PC:

I verify privacy settings but 3CX client app doesn't appear in the list where I can set allow/disallow access to microphone.

This is what usually happens:
1) Start 3CX client
2) Make an external call --> microphone doesn't working
3) Call an extension (internal call) --> microphone works!
4) Make an external call --> now microphone works!

... After first call to an extension, I can call also external number.

Have you installed Jabra Direct and updated firmware etc on the headset?

We have had issues somewhat like this, but it was resolved by setting 3CX as the preferred softphone in Jabra Direct.

I've installed Jabra Direct, I've updated firmware and I set 3CX as preferred softphone but I have always the same problem (I test this many days).
When I turn on my pc, jabra direct and 3CX client start automatically but when I make the first call Jabra micr doesn't work (nobody hear me). Then after many seconds also micr start to work.
This problem happens also to my colleagues.
