Web client says "trying" then hangs up.

When trying to dial from chrome web client in windows 10 it says "trying" for about 10 seconds then hangs up. This is happening while phone is selected, if we select web client then it works well.

Also, do calls from and to the specific IP Phone (the one linked to the webclient) work okay?
